Solid subtract not working?

Anonymous — Fri, 06 May 2016 14:13:34 GMT

Am using Autocad 2016.

A book I am reading says to use Solid subtract to delete blocks from the walls at the door locations.

I tried this but nothing gets deleted. Why is this?

Thank you for your help.

Subtract a BOX it can do; but a BLOCK, no it can't.

Sorry, I meant to say Box, not Block.

Attach your drawing so someone can test it.

Hi @Anonymous,

You are using surfaces instead of soild walls, so you must subtract box/block from both sides of wall or create your 3D walls use Polysolid command in the solid tab of ribbon.

You still beginner @Anonymous I advice you to learn some courses in 3D.

This is the Polysolid

I succesfully drew Polysolids.

But when I delete the boxes, no holes remain. It just disappears.

Attach file here that exhibits this behavior.
