Ultra Lightweight 3D Models.

Do detail components "sweep" along invisible model lines?

That's the basic idea...

For a chair that gets pushed under a desk, you probably need lines front to back as well...

Interesting... for a chair and table, I'd simply set the height of the invisible line for the table higher than the invisible line for the chair... I'm trying to think of where that would be less successful.

hmm.. If I draw an invisible line 1' tall then set the BOTTOM of my Primary Range to 1'-1" the detail component appears totally black in my project. I guess the answer is, don't set the BOTTOM of your Primary Range higher than the invisible line extends.

You can also add in details for front and side views. If you had a vertical line on the back of a desk and push a chair partway under which used a line at the front of the chair - then the table would be in front of the chair rather than seeing the chair in front of the table in elevation.

Ahh, excellent. Thanks for the tip.

Why are we spending so much effort to make a 2D symbol. Should the problem be refocused on to Revit's graphic engine?

File size?
This is a non-issue. See my Division -10,000- 3D toilets below? The Revit project is 1.2 megs (the entire RFA).
Performance?
When you turn off the toilets Revit is as snappy as ever. It's only when they are visible does Revit start to lag. 2D toilets are slightly better - but not much.
Appearance?
Yes. Ugly potato shaped toilet with unacceptable plan / elevation representation.
What if you had more control how Revit renders a 3D element, similar to a Toon shader in 3D MAX, a symbol may not be necessary.
