Can't Preview wall in Type Properties

[dfriesen]

I have a Basic wall type that won't allow me to use the Preview function when in the Type Properties or Edit Assembly dialogs. The Preview button is there, but nothing happens when I hit it. Other walls in the project Preview just fine, but even if I copy/paste the problem wall to a new project, it still cannot be previewed.

Thinking there may be too many layers (10), I've tried deleting layers of the wall, down to a single layer, but no luck.

Any advice?

Try re-creating it, from a compound wall that previews correctly.

Yep, that's what I'm resorting to now. Might have just been corrupted somehow.

Sample height was the problem. Changed from 16 to something bigger, and it works fine.
