GDL object and Graphic Override

TJR — Tue, 31 Dec 2024 16:12:48 GMT

Hi, everyone.

When I work on urban plan studies we normally use fills to draw the plots, buildings etc. and then give these Element-ID's to be able to override de buildings colour for specific plan views. building type etc etc. And after we have the 2D plan we model a basic 3D plan too.

So i was thinking about making an GDL object where it has a plot and building volume in 2D/3D in one go.

Now I seem to have hit a roadblock that seems like I can't give for example the building(gray fill) a unique ID or property which I can override with graphic override. It will always override the whole object?

Is it correct that this is not possible within a GDL object or is there a way to make this happen?

Thanks!

Why not use a slab instead of a fill? And there you can solve your two subsequent points: 1. having a 3D model at hand, once you draw the site plan 2. having the ability to make use of graphic overrides.

It may be slightly more time-consuming upfront (once you set up everything) but at least, for me, the reward/effort ratio makes it worthwhile.

It is possible if you make your 2d object out of 3 different fill types: draft fill, cutfill and building material fill:

You'll have to make 3 overrides, one for each fill type:

Override draftfill:

Override cutfill

Override buildingmaterial fill

The object without and with the graphic overrides:
