Question:

  • Why can't I create elements?
  • Why can't I move a drawing?
  • Why are elements not created correctly?
  • Why does the program crash when I import a DXF file from the land registry office?
  • Why is the outline of a circumscribed area not detected correctly?
  • Why can't I calculate shadows?
  • Why are elements not displayed correctly in animation?
  • Why are parts of dimension text missing?
  • Why do the contents of the screen suddenly rotate?
  • Why can't I get a preview when I move or copy elements?
  • Why are areas not calculated correctly?




Finding the reason for these problems:

Check whether an offset is set in the project settings (File -> New Project, Open Project-> select the project and open the shortcut menu -> Properties; Allplan 2009 and earlier: Tools -> Options ->Advanced Draft -> Settings). If there are offset coordinates, clear the check box.

Select Tools -> Measure(->)Coordinates.
Click in the middle of the drawing in plan view.
If there are very large values (for example, x/y/z greater than 5000 m), you have found the reason for these problems.

The system has problems calculating and displaying data with very large coordinates. The more data you have with very large coordinates, the greater this effect.



Solution:

  • Click Tools -> Options... -> Desktop environment -> Generaland select Optimize working with large coordinates(Allplan 2009 and earlier: Tools -> Options -> Global Options -> Miscellaneous tab -> Optimize working with large coordinates). After this you must restart Allplan. Otherwise, this setting has no effect.

This is a user setting you must define separately for each user.

  • Usually, the best solution is to move the data towards the Allplan origin. Use the "Move" tool. When Allplan prompts you to specify the target point ("To point"), select Global point in the dialog line. You can find detailed information in the help for Allplan. Look for the Global pointtopic.



Note:

If the data are still not displayed correctly, do the following:
Exit Allplan -> Services application-> Service -> Hotline Tools-> cleanup -> start Allplan.

Question:

When I create a hidden line image of an isometric view (Viewmenu -> View-> Front Left, Southwest Isometric Viewor any other isometric view), Allplan does not use the original dimensions so that the resulting lengths are distorted.
How can I make sure that Allplan creates the hidden line image based on the actual dimensions?



Background information:

In accordance with DIN, an isometric view is calculated as follows:
Allplan chooses the projection plane and the axes so that all the axes are shortened equally = axonometric projection of an isometric view.
This is the case when all the angles are the same: 120 degrees. The result is an equilateral triangle. Each side is shortened by two-thirds or 0.8165. However, the edges parallel to the axes are usually not shortened.

Isometric view:


Angle of the coordinate axes:
x axis: 30 degrees to the horizontal
y axis: 30 degrees to the horizontal

Shortening:
x : y : z = 1 : 1 : 1 (using a factor of 0.8165)



Solution:

When calculating an isometric view, Allplan shortens all directions by the same value (x:y:z = 1:1:1), using a factor of 0.8165.
All you need to do is resize the result in the destination drawing file by the corresponding factor (1.22475) in the x and y directions. After this, all the edges are displayed at their actual size and can be dimensioned.
