Multi material GDL objects in sections

Sam Karli — Sun, 04 Sep 2016 18:23:26 GMT

Hi,
when I make a GDL object from objects with multiple materials (layered wall / slab, object made by Profile Manager), object's material (fill) will become homogeneous in sections.

Is it possible to have it to retain its multiple materials/fills?

i tried this and then checked the generated GDL script.
It seems that you are right, there is some bug in the generated script which causes all skins to be displayed in section with the same section fill.
This is incorrect because the data and section fill parameters are there in the GDL Object, only the commands that set the section fills to the proper values are incorrect.
So I will report this to GRAPHISOFT.

Before a 3d entity that has to be presented with custom fill You have to define sect_fill.

Actually, in the example I checked the script was using the SECT_ATTRS GDL command, which I guess is a more modern way of setting Section attributes in GDL.

Thanks,
hopefully will there be a hotfix for that, the ArciCAD SE should get it as well.

Interestingly enough, it's not a 'serious' internal bug, it's just the generated gdl script that has the same materials for all the layers, etc in its sect_attrs definitions.

When the sect_attrs are handled correctly (and the group-engroup-killgroup stuff removed), the result is correct.

Obviously ac works as follows:
-creates (two or more) solids
-adds them through (quite too many) solid edge operations
-and the result is, because of the seo, ist a homogeneous material. If the seos are blocked and the sect_attrs are handled correctly, the result is ok.
