Why is Allplan running so slow?
Check the following points:
1. Current version
Make sure you work with the current Allplan version.
- Do the following or ask your system administrator to do this:
Open Allplan and click the ‘?’ icon in the upper right-hand corner. Click ‘Update Allplan’.
Select 'Find now'. If Allplan finds updates or hotfixes, download the installation packages.
- Deactivate the virus scanner while your are installing updates or hotfixes. This might require administrator privileges. Contact your system administrator if you have problems.
- Right-click the Allplan icon on the desktop. A shortcut menu opens.
Select ‘Run as administrator’ and click ‘Yes’ to confirm the following message.
As a result, Windows security settings do not block the installation.
2. System requirements:
Check the hardware and software required for your Allplan computer.
2.a)Download and run the system test.
Check the notes.
2.b)Check the Allplan system requirements:
2.c)You can find information about graphics cards at
2.d)You can find server operating systems you can use for the central file storage of Allplan at
3. Hotline tools:
Start the Services application, open the ‘Service’ menu and select ‘Hotline Tools’. To save your settings, select the following tools.
- savestd: Saves user defaults.
- savereg: Saves CAD registry settings.
Start the Services application, open the ‘Service’ menu and select the following ‘Hotline Tools’:
- cleanup: Initializes the display.
- cleanstd: Resets CAD defaults.
- cleanreg: Resets CAD registry settings.
Check whether this has solved the problems.
If this is not so, restore the settings you just saved. To do this, start the Services application, open the ‘Service’ menu and select the following ‘Hotline Tools’:
- reststd: Restores saved user defaults.
- restreg: Restores CAD registry settings.
4. Color scheme selected in Allplan:
Start Allplan, open the ‘View’ menu, point to ‘Toolbars’ and select ‘Customize User Interface’. Open the ‘Customize’ tab and set ‘Color scheme and icon design’ to ‘Windows’.
5. Check the availability of all projects that are not online (if you use Workgroup Manager):
Start Allplan, open the ‘File’ menu and select ‘New Project, Open Project’. Deactivate ‘Check availability of all offline projects’.
6. Virus scanner
Check whether an anti-virus program is running in the background of the computer or server.
If so, reduce protection to "programs only".
Scanning "all files" can take a long time, considerably slowing down your computer when you switch between projects or exit the program.
You can exclude the Allplan installation folders from real-time scanning.When you start the Services application, you can see a list of the folders to be excluded.
You can find more information at
Changes in the settings of the virus scanner only come into effect when you re-start the computer.
7. Aero desktop effects
Deactivate the Aero desktop effects of Windows.
To do this, open the Control Panel, select ‘Ease of Access’ and go to the ‘Make things on the screen easier to see’ area.
Select the ‘Turn off all unnecessary animations (when possible)’ option.
8. Name resolution on the network
If Allplan takes several minutes to start, name resolution on the network may not work.
To check this, do the following:
Right-click the Windows Start Button, select ‘Run’, type in ‘cmd’, click OK, type in ‘Nslookup’ and press ENTER.
Go to the line following the > character, type in the name of the Allplan data server and press ENTER.
The reply starts with the name and address of the server providing name resolution.
You can find the name and address of the Allplan data server in the second group.
If problems occur, contact your network administrator and ask him or her to configure name resolution correctly.
9. Speed of Allplan projects
Check whether some Allplan projects are slower than other Allplan projects.
Start with the empty project and check whether it is slow too.
After this, select any other Allplan project.
If it is only the current project that is slow, the problem may be caused by the data of the current project.
In this case, the data of this project must be analyzed in detail.
Contact technical support.
10. Network: checking out Allplan using Workgroup Manager
If you use Allplan with Workgroup Manager, you can check whether the problems are caused by the network. To do this, check out the workstation with the project in question and use the project on the local Allplan workstation.
You can find detailed information on checking out an Allplan workstation using Workgroup Manager in the
Services application. Open the ‘Help’ and select ‘Workgroup Manager’.
After you have checked out the workstation, Allplan no longer accesses the central file storage of the server.
If this has solved the problems, they are caused by the network. In this case, the network must be checked in detail.
Contact your network administrator and ask him or her to do this.
If the project is still slow, the problem may be caused by the data of the current project.
In this case, the data of this project must be analyzed in detail.
Contact technical support.
11. Log files and system information files
If all the points above do not solve the problems, technical support requires more system information about the computer running Allplan.
- So, we would be grateful if you could send us a support request (Allplan Hotinfo with Allplan logging).
To create a support request, start the Services application, open the ‘Service’ menu and select ‘Create support request (Hotinfo)’.
Several dialog boxes open. Select ‘Technical Support Allplan’ and ‘Enquiry with Allplan logging’. Enter all the data required. Finally, click ‘Finish’.
Another dialog box opens, prompting you to start Allplan. Click the ‘Start Allplan’ button.
Allplan starts, logging all processes.
Try to reproduce the problem as exactly as possible.
Exit Allplan as soon as possible, reducing the data in the log file to a minimum.
Then click ‘Next’ to generate the support request with the log file.
You can find more information about Hotinfo at
- To analyze the Windows system environment, we would ask you to send us the logs created by Windows Event Viewer of your computer.
To start Windows Event Viewer, right-click the Windows Start Button, select ‘Run’ and type in ‘eventvwr.msc’.
You can also type in ‘Event Viewer’ in the search box of Windows. This displays the link file to the Windows event logs.
Using Event Viewer, create *.evtx files for the application log and the system log in the ‘Windows Logs’ area and for the ‘Administrative Events’ log in the ‘Custom Views’ area.
Please send us the files.
How can I work from home with Allplan without a direct LAN connection to a common file storage folder?
1. Working from home with direct access to the central data
If you want to work together on projects, you can use Allplan Share, Allplan’s cloud solution, to work with Allplan without a LAN connection to the central file storage folder. This is only possible if Allplan is installed as a standalone version on a computer without access to a central file storage folder; otherwise, Allplan does not start. If the computer is part of a workgroup installation, the computer must be checked out and used outside the LAN (like a standalone workstation). Data access is via cloud services.
This is only possible if you use Allplan Share for cloud storage.
Working with Allplan Share is just as simple as working at a standalone workstation. You and several other users can access and edit a project at the same time.
To get more information on Allplan Share, use the following link or contact your sales partner:
You can also find further information on Allplan Connect; use the following link:
VPN is not useful for common project storage.
Allplan exchanges many files with the data server. VPN uses advanced encryption, which considerably slows down data transfer.
A connection via VPN is not approved for Allplan because data might get damaged even if the connection is interrupted only briefly. In addition, working over the internet is extremely slow if the internet connection is not fast enough (at least 100 Mbit).
Allplan does not support a VPN connection with IPv6; Allplan detects only IPv4.
Make sure that the VPN connection does not switch to sleep mode.
Please note that we cannot provide support for this constellation.
2. Working from home without access to the central file storage (working locally):
2.1 Allplan with workgroup manager:
If workgroup manager is included in your license, you can check out a computer or laptop with projects from the workgroup environment. You can then work from home without access to the server. The projects on the computer or laptop that is checked out are locked for the CAD users on the network. These users see the comment you entered when you checked out the computer.
You can find instructions at
When you use a license server, you can get the license via a VPN connection or borrow the license beforehand:
2.2 Allplan without workgroup manager:
Using the office computer
If you have neither workgroup manager nor network access, you must uninstall Allplan and install it again by specifying the local paths. To work with a project, you must back it up and then import it to the local installation.
Using a new (private) computer
If you want to use a new computer to work from home, you must return the license at the office computer and then use this license to install Allplan on the new computer.
We recommend that you do not mix data from the office computer and the private computer. Merging data later involves considerable time and effort.
Use the following link to find out how to transfer projects:
I just installed an upgrade. How can I convert all the projects at once?
Back up all the projects beforehand!
Do the following:
- Exit Allplan on all workstations.
- Only when working with Workgroup Manager:
Log in as the Allplan administrator (sysadm).
- Start the Services application.
- Only when working with Workgroup Manager:
Make sure all the computers where projects are located are up and running.
To check this, select:
Services application -> Workgroup Manager -> Information -> Display Project List(the second column displays the computer where the project is located).
- Go to the computer where you want to convert the data and set the drawing file size to the maximum value:
Services application->Service ->Hotline Tools->docsize ->512 (or 1024, if available) ->OK
After data conversion, you can set the drawing file size back to the initial value.
- Start converting the data (use the computer where you have changed the drawing file size):
Services application ->Service ->Hotline Tools -> datwaprjs: convert data of all projects
If you reply "Yes" at the following two prompts, the program will convert the data of all projects.
The time it takes to convert the data depends on various factors:
- Number of projects
- Size of each project
- Performance of the computer converting the data
- Network performance
It is possible to start data conversion from several workstations at the same time.
Allplan from version 2011
Parts of Allplan 2011 have been reprogrammed and are completely new. Allplan uses a graphics library, which has been developed especially for CAD programs and visualization tasks. Depending on the data type and application, the display speed of Allplan is much higher than that of earlier versions, and refresh operations are considerably shorter. What's more, you can create hidden line images in real time.
This new technology is not a one-to-one implementation of the software-based solution in the previous version. Instead, a hardware-based approach is used. When it comes to data processing, the graphics card takes on much of the work. The different behavior of these two technologies that may occur in some parts is inherent. Therefore, the resulting display and refresh operations may differ slightly from what you are used to.
General graphics card requirements for Allplan
To fully exploit hardware acceleration capabilities, you require an Open GL 2.0 and DirectX10 (chip-based) compatible graphics card with 512 MB or more memory. Although Windows XP does not support DirectX10, Allplan only requires the chip-based support of the graphics card to manage the graphics library. OpenGL 2.0 is used in 2D and in visualization windows. These changes employ the latest technology in graphic display, so selecting a capable graphics card, and using the proper drivers is essential.
For more information on graphics card specifications, go to:
Professional graphics cards versus Consumer-Level cards
Graphic card manufacturers typically have different product lines targeted for "gamers" and "professional users". While the hardware setup is very similar in case of both cards, there are key differences in their firmware and driver. "Consumer-Level cards" (such as Nvidia GeForce and AMD/ATI Radeon) are optimized for 3D games and technologically designed for DirectX10, as speed is more important than image quality.
Typically a 3D model in a game contains a low number of polygons with textures applied to them, while in CAD applications polygon count is high, and the image quality of wireframe models or shaded models is more important than navigation speed. Also, professional cards' memory usage is optimized for using multiple application windows, while in gaming this is not relevant.
Another key difference between the two product lines is the way they are delivered and supported. Professional cards (such as Nvidia Quadro and AMD/ATI FireGL/PRO) are built according to the video chip manufacturer's references, so you can always be sure that the driver delivered by the video chip manufacturer (such as Nvidia or AMD/ATI) fits your card.
The manufacturers of Consumer-Level cards (such as ASUS, Sapphire, Gigabyte, PNY and so on) may diverge from the chip manufacturer's references, so their drivers may not be compatible with the chip manufacturer's reference driver. Also, the product life cycle and driver release cycles are much shorter in case of gaming cards, usually 6 months up to 1 year at most and a 1-year warranty period maximum.
Example: comparison of graphics cards
Professional graphics cards / workstation
Professional graphics cards versus Consumer-Level cards
Professional graphics cards differ considerably from "Consumer-Level cards" for private users with regard to specific market segments with special requirements:
- Extensive application tests and certifications with CAD providers
- Optimized and advanced support for API as well as further developments
- Longer product life cycles and availability
- Direct product support
- Longer warranty period
Nemetschek Allplan GmbH cooperates with Nvidia und AMD to test graphics card drivers for the Nvidia FX Quadro/ Quadro and AMD/ATI FireGL/ Fire Pro series. These product lines are tested, certified and recommended for Allplan by Nemetschek Allplan Systems GmbH.
For more information on certified graphics cards, go to:
There are four different categories and areas:
|Graphics card||Application||Quality tests||Status|
|Gaming graphics cards||3D Games||Tested / not tested||Not recommended|
|Professional graphics cards||3D basis||Certified and recommended||End of life|
|Professional graphics cards||3D performance||Certified and recommended||End of life|
|Professional graphics cards||3D high performance||Certified and recommended||End of life|
Recommended graphics cards for laptops (Windows)
For reasons detailed above, we cannot recommend any specific card and driver combination for laptops. However, there are professional graphics cards available for high-end laptops such as NVidia FX Quadro & Quadro NVidia "M" or AMD/ATI FireGL & FirePro "Mobility".
These graphics cards are just as good as their desktop counterparts.
Laptops with Consumer-Level cards have been tested only briefly and cannot be recommended. We have had bad experience with on-board Intel graphics cards.
Graphics cards drivers for Apple Macintosh
Since Macs come with a default graphics card (on-board or gaming), and the drivers are bundled with system updates, we cannot recommend a specific card.
Graphics cards for MacOsX 10.6 (Leopard) or later and Boot Camp support Open GL 2.0 and DirectX10. Currently, there is only one series that is equipped with a professional graphics card: Mac Pro with NVidia FX4800 for Mac.
Notes for Allplan and Macintosh:
- There is no provision for a direct installation under Macintosh.
- Access to Windows must be straight from the Boot Camp installation.
- For performance reasons, Parallels Desktop cannot be used in conjunction with Nemetschek Allplan.
We kindly ask you to understand that Nemetschek Allplan cannot provide support for Boot Camp installations.
Installing graphics cards drivers (Windows)
Graphics cards only work properly if they have a hardware provider supplied driver (not system built-in driver) installed correctly. It may happen that remnants of a previous installation interfere with the current driver installation. If you experience display issues with the drivers listed below, please "clean-install" the driver again. "Clean-install" means removing all previous driver files before installing a new driver. Unfortunately, a simple uninstall may not efficiently remove all components of a driver. There are tools that can do it, like ATI's cat uninstaller or third-party tools like driver cleaner or driver cleaner pro 1.5.
Graphics card drivers for laptops (Windows)
In most cases, graphic card drivers for laptops are supplied by the laptop manufacturer, and graphic card provider supplied drivers will not install on laptops. This makes it practically impossible for us to test laptop graphics cards. If you are experiencing display issues with your laptop, and your supplier does not offer you a driver update, you might try - at your own risk - to tweak a desktop driver to work on your laptop. Note that this is obviously not encouraged by your laptop supplier.
Which server or server operating system can be used for data storage of Allplan.
Since Allplan 2018 we recommend Windows Server 2016 as the server operating system for pure data storage and since Allplan 2019 also Windows Server 2019, since Allplan 2022 Windows Server 2022.
When selecting the server operating system, please also take into account the interaction with the client operating systems used.
For Windows Server 2012 R2, the "development phase" (fixing bug fixes, etc.) was discontinued in 2018.
However, Microsoft will continue to provide extended support (closing security gaps) until 10.10.2023.
The same applies in this respect for the Windows 8.1 operating system used in the same period.
Due to this fact, it cannot be ruled out that the further development of the Windows 10 operating system and the "technological standstill" of Windows Server 2012 R2 could lead to discrepancies when combining these operating systems at some point.
However, Microsoft should be able to guarantee compatibility for the operating systems used in the future.
Windows Server 2016 - Windows 10
Windows Server 2019 - Windows 10
Windows Server 2022 - Windows 10 and Windows 11 respectively.
If Allplan is also to be installed on the server operating system (e.g. Citrix), the corresponding release in the system requirements must be observed. For Allplan 2016/2017 this is e.g: Windows Server 2012 R2. For higher Allplan versions this is e.g: Windows Server 2016.
General information about the system requirements here:
Notes on NAS systems:
NAS server are not generally recommended. Because the product variety and quality is very diverse, no effective quality control can take place. We can give no guarantee about operability. In the past we had performance or stability problems, false representations up to the loss of data in some cases.
This phenomenon occurs most in NAS systems of the lower price segment, which have not installed sufficiently fast hardware. If nevertheless a NAS system is to be used we recommend generally a high-performance hardware and the use of the operating system "Windows Storage Server 2012".Download PDF FAQ_EN_Server_operating_system_for_the_data_storage_...
Which graphics cards are recommended for Allplan?
Follow this link to see a list of the AMD/ATI & NVidia graphics cards manufacturers that are CERTIFIED FOR ALLPLAN.
We have tested the OpenGL functionality and the animation performance of various Allplan modules with specially prepared data with each of the cards available.
The tested drivers can be found on the homepage of the individual manufacturer. The driver versions that were used in the tests are included in the tables so that you can compare the data. However, we strongly recommend that you always installthe current driver of the manufacturer.
It is a good idea to check your system using the system tool you can find on our homepage:
Allplan 2011 was revised completely for accelerated graphical representation.
To guarantee full performance support for Allplan 2011 and later, please check that your graphics cards meet the hardware requirements for DirectX 10 & OpenGL 2.0 (chip-based). In addition, you need to install the current drivers. Allplan will automatically switch to the conventional drawing method when it starts and finds old graphics cards that do not meet the requirements stated above.
For more information on graphics card specifications, go to
We kindly ask you to understand that products of other manufacturers that are not mentioned have not been tested and therefore cannot be recommended.

1)System requirementsfor Allplan Share
Allplan Version 2018 or higher
Network infrastructure required
A 20-Mbit/s Internet connection for downloading and uploading data
At least a 50-Mbit/s Internet connection for downloading and uploading data
You have two options to buy the Allplan Share option.
1. You can visit the Allplan Shop at ‘shop.allplan.com’.
Allplan Options -> Allplan Share
a. Specify how many licenses you want to buy and add the Allplan Share option to the cart.
b. Follow the instructions displayed and buy the Allplan Share option.
After you have bought the Allplan Share option, the licenses will be assigned to your Bimplus team. You can manage these licenses using ‘My Account’ - ‘Subscriptions and Users’.
2. You can contact the Allplan sales partner in your area.
3) Assigning licenses
Regardless of how you buy the Allplan Share option, you can manage the Allplan Share licenses in the Allplan Shop. Go to the ‘Subscriptions and Users’ area. As an alternative, you can also manage the licenses on the Bimplus portal. Here, go to the ‘Team members’ area.
Allplan Shop - ‘Subscriptions and Users’
1. Log in to the Allplan Shop and open ‘My Account’.
2. Click ‘Subscriptions and Users’ to see your licenses.
3. Select the Allplan Share option on the tab.
4. You can assign one or more Allplan Share licenses to team members. To do this, select the user in the list and assign the license by selecting the check box. You can remove the license at any time by clearing the check box.
If the list does not include the user to whom you want to assign a license, click ‘Invite new Bimplus team member’, enter the email address of the new team member and select a role.
As soon as the new team member has accepted the invitation, you can find this person in the list.
4) Using Allplan Share
To use the Allplan Share option, you require Allplan 2018. The Workgroup Manager option is not necessary.
Starting a project
You have three options to start an Allplan Share project:
1. You can create a new project and save it on Bimplus by setting the location to BIMPLUS. To create a Bimplus project with Allplan Share content, you require ‘Bimplus team owner’ or ‘Bimplus team admin’ privileges.
2. You can copy an existing Allplan project to Bimplus by selecting ‘Copy to’. You can then share this project with other project partners. This does not affect the source project.
3. You can move an existing Allplan project to Bimplus by selecting ‘Move to’. This moves the source project to Bimplus. As a result, this project is no longer available on the local computer or local network.
5) Managing users and assigning users to the project
Allplan Share is a cloud-based solution. Therefore, Allplan Share uses the Bimplus user management for project collaboration. As a result, Allplan Share is independent of local user management systems like Workgroup Manager.
After you have copied or moved an existing Allplan project to Bimplus, you must reassign the users to this project. Otherwise, they cannot access this project.
To define the project members, use the Bimplus project administration. In addition, you must invite new project members to the Bimplus project.
If these Bimplus project members are to use the Allplan Share option too, you must assign an Allplan Share license to each member in advance (as described in ‘3) Assigning licenses’).
How can I speed up installation and the process of opening dialog boxes in Allplan?
Change a setting on the Control Panel:
Start -> Control Panel -> Internet Options -> (Advanced tab) -> Settings -> Security -> Check for publisher's certificate revocation -> clear this check box -> OK
Allplan is certified for Microsoft Windows 7 and has the "Compatible with Windows 7" logo. This certificate guarantees higher security and reliability but requires special programming such as signing DLLs.
When these components are accessed, the program checks whether the publisher's certificate is still valid.
This requires that the relevant computer is connected to the Internet. If this is not so, you can switch this option off.
This boosts performance.
Why does the "a connection to the Internet could not be established while checking certificates" message appear when I start Allplan?
The relevant computer cannot check the certificates.
According to a setting in the computer's Internet Options, certificates are checked by default.
If this check fails as, for example, the computer cannot connect to the Internet, some Allplan windows can take a long time to open.
If you have performance problems when opening dialog boxes in Allplan, clear the "Check for publisher's certificate revocation"option.
To do this, select "Start -> Control Panel -> Internet Options -> Advanced -> Security". All you need to do is clear the relevant check box.
The certificates' validity is checked for Allplan program files.
Certificates are used to confirm the authenticity and integrity of programs.
Why does Allplan become slower and slower while I’m working?
This might be caused by the Firebird database system installed on the computer.
The service of the Firebird Guardian - buhlMB database might cause Allplan to become slower and slower.
Enter “system configuration” in the search box in the lower-left corner. Switch to the “Services” tab.
Stop this service if you are not using the database application right now.
In a certain case, the performance of Allplan was considerably impaired only after a certain period of about 90 minutes after startup. It did not make a difference whether Allplan was directly used after startup or only later.
