objects errors

[Anonymous]

Hi everybody, I have for some time now, problems with some objects in the 3d window, such as the curtain wall. I usually don't have problems in drawing them but when I make a perspective or axonometry I got some strange error messages (attached), it also happens with some other object wich I was not able to determine
could someone tell me how to fix it or at least explain what is the problem so I could fix it.

By the way, I can still get my 3d model done telling it to continue on the error message prompt. Go wonder?

Hi AlchiCAD

The 2D and the 3D of an object are not completely linked. You can perfectly a 2d View which works fine and a 3D view full of error. Sometimes, some dimensional parameters than you input can 'create' 3D errors like the yours "polygon is degenerated" indicate than a part —or more in your case— of your object have a bad definition for archicad.

Try to change parameters to see if the errors are still here.

This could be caused by something such as setting a dimension too small to generate part of the model. The GDL programmer should write code to check for this, but it is not always easy to predict all the possible sources for error.

An example would be setting the height of a door transom to less than twice the thickness of the jamb. The transom sash could end up with zero or negative dimensions. The exact cause and nature of the error(s) will vary (widely) with different parts.
