Thanks mpm990, Jörg and Haidu for yours answers! :-)

I'm totally agree with mpm990: working with global values is more efficient than working with folies. I'm creating others smartparts, like doors and windows, and the writing of the code considering folies is really long and tedious. In the wishlist, could be interesting to organize the looooooong code scripting, by substructuring like a tree structure, using text colour, etc...

As Jörg wrote some posts ago, he explain that they are working about the refresh of the Smartpart like doors, etc.. Also could be interesting that the smartparts automatically refresh when it change any global parameter, like the "Drawing type set" (Zeichnunstyp) o "Reference Scale" (BezugsmaBstab).

In essence, it would be very interesting that the Smartparts make at least the same as the Smart Symbols (Makros).

About QUESTION 3 ---------------------------------
Haidu, I have some questions about polylines (sorry, my questions will be very basic!)
QUESTION 3B In the first script you wrote:

put 0,0,15,
1,0,15,
1,1,15,
0,1,1000
poly2_ num_sp/3,1+2+4,get(num_sp)

The value 15, whats this value?
And the num_sp, is the value 15?

About the odd commands ---------------------------------
Sorry, I haven't information about sect_fill and SECT_PATTERN commands. Perhaps Jörg can explain something about it.

Thanks!
Xavi

Hi all! after a week off, I'm back here!
Thanks Haidu for your answers! :-)
I'm not a programmer, and there are plenty of commands that have not yet tried. Now I'm starting to master the commands Poly_ and Poly2_, creating polylines with arcs using the status code, and other commands like PUT, GET, USE, num_sp.
I had to search and read Archicad GDL documentation (documentation with many examples) but it would be impossible for me without these documentation (and without the help of this forum), because there aren't enough deep documentation about SmartParts.

The next step is to learn and correctly use the commands Hatching and Pattern. Be prepared, I'm sure I will have many questions to do! :-)

Mmmm.... how I can fill a polyline with a pattern? I'm trying it but I can't. This is my smartpart script :-)

DEFINE PATTERN "tramita" 40 , 1 , 0 , 1 , 1 , 0 , 0 , 2 , 0 , 0
PATTERN tramita
POLY 4 , 0 , 0 , REF_X , 0 , REF_X , REF_Y , 0 , REF_Y

Thanks a lot!
Xavi

Thanks Thomas, you are right! Now works ok :-)

There is some confusion on how to use "" in various commands of the Smartparts, in the second rows. For example, when you define a Hatching or Pattern, the sample script is:

DEFINE PATTERN "trama" 40 , 1 , 0 , 1 , 1 , 0 , 0 , 2 , 0 , 0
PATTERN "trama"
POLY2 4 ,7, 0 , 0 , REF_X , 0 , REF_X , REF_Y , 0 , REF_Y

But, when you define a Text, it's no necessary to use "". like the next sample script:

DEFINE STYLE "text_100" arial , 0.35 , 8 , 1
STYLE text_100
TEXT2 REF_X / 2 , 0.005 , STR ( "%.2" , REF_X ) + "x" + STR ( "%.2" , REF_Y )

------------------------------------------

And now, another question. If I define a Pattern Parameter, with the name fill_patt and value 40, how would be the script? I'm trying this, but it doesn't work:

PATTERN Fill_Patt
POLY2 4 , 0 + 2 + 4 , 0 , 0 , REF_X , 0 , REF_X , REF_Y , 0 , REF_Y
