PROJECT2{??} and SEO ?

gaba — Wed, 24 Jun 2026 20:57:13 GMT

Can any variation or setting of the PROJECT2{??} function show the results of an SEO operation on a GDL object in a 2D plan?

Operating system used: Windows 10

Not that I know of.

Project2 is simply showing what was scripted in the 3D script.

The 3D script has no idea of how the object is being affected by an SEO, just that is is being affected by an SEO.

All you can do is determine if an SEO is taking place and offer an alternative script which the Project2 could show.

But the alternative script is what you tell it to do, not what is actually happening with the SEO.

Does that make sense?

Barry.

in general, SEO's don't translate through to plan view, regardless of which tool is used. I think because the SEO trimming body does not actually 'trim' the element. The geometry still exists above/below/inside the target element(s); it just doesn't show (until you select the elements).
so a plan view of an object using project2 is still showing the projection of the 'hidden' portions of the object.

Not an answer but maybe useful or related, depending what you need the SEO to do.
1. If you need to see the true projection with the cut, you can create a plan 3D document
2. Finalise the operation - convert to morph
3. Project2{4} has an option of cutplane and you can set its height
4. SEO inside GDL with SUBGROUP command but this means operator needs to be part of the object
