Defining Extrusion Geometry in GDL code

jakubc7 — Thu, 07 Mar 2019 03:35:54 GMT

I am trying to create an object which is an extrusion of a profile (too complex to define manually with user input code).
Is there a way to implement 2D geometry (from polyline or fill) and use within a 3D GLD code of PRISM_ (or something more suitable).
I tried making a wall and/or column with a complex profile and "dragging" it into 3D code but that spits out very complex code which is unmanageable. I was hoping I could drag the fill or poly code coordinates and use them to define my _PRISM geometry?
I attempted this (using code from 2D poly or fill) in the past but never had success. Does anyone know a good way of achieving this?

You can reference Complex Profiles in GDL and extrude those. There is a thread from when this was introduced and it contains a link to the example object.

You can use the x & y co-ordinates from a POLY2, but you may have to watch the masking value or status code when you use them with a 3D shape.

For example in 2D

poly2_       6,      7, 
                   0,            0,      1, 
                   1,            0,      1, 
                   1,            1,      1, 
                 0.5,            1,    900, 
                   0,          180,   4001, 
                   0,            0,      1

but in 3D

prism_       6,      1.0, 
                   0,            0,      15, 
                   1,            0,      15, 
                   1,            1,      15-2, 
                 0.5,            1,    900, 
                   0,          180,   4015-2, 
                   0,            0,      -1
