Best way to export Archicad model in GDL

[Mario Sacco]

I'm trying again to understand if there is a better method to export geometry from Archicad in GDl.

The general problem is for slab with rounded edges. I would like to have the possibilities to control the resolution in 3d. 

If you export a slab in GDL 2d The code recognize the rounded edges:

poly2_b{5}      17,      1,      0,      3,      1,      0, 
                   0,            0,            1,            0,            0,            1,            0, 
                 0.1,            0,      1, 
                 0.4,            0,      1, 
                 0.4,          0.1,    900, 
                   0,           90,   4001, 
                 0.5,          0.1,      1, 
                 0.5,          0.8,      1, 
                 0.4,          0.8,    900, 
                   0,           90,   4001, 
                 0.4,          0.9,      1, 
                 0.1,          0.9,      1, 
                 0.1,          0.8,    900, 
                   0,           90,   4001, 
                   0,          0.8,      1, 
                   0,          0.1,      1, 
                 0.1,          0.1,    900, 
                   0,           90,   4001, 
                 0.1,            0,      1

If you export a slab in GDL 3d the code doesn't recognize the rounded edges:

Anybody have found a method to solve this issue?

Another issue is the possibility to create vertical slab and con vert them

You have no control how Archicad converts elements to the 3D script.

However, you could use the co-ordinates from the 2D script in a PRISM_ command in the 3D script.

Just add '15+64' for the masking values.

prism_      17,      1,      
                 0.1,            0,      15+64, 
                 0.4,            0,      15+64, 
                 0.4,          0.1,    900, 
                   0,           90,   4015+64, 
                 0.5,          0.1,      15+64, 
                 0.5,          0.8,      15+64, 
                 0.4,          0.8,    900, 
                   0,           90,   4015+64, 
                 0.4,          0.9,      15+64, 
                 0.1,          0.9,      15+64, 
                 0.1,          0.8,    900, 
                   0,           90,   4015+64, 
                   0,          0.8,      15+64, 
                   0,          0.1,      15+64, 
                 0.1,          0.1,    900, 
                   0,           90,   4015+64, 
                 0.1,            0,      -1

Thank you @Barry Kelly 

Modify 2d to 3d is the method that I generally I use.
