CGTalk Boolean Problem

I'm trying to model a coffee cup with lid and I'm having problem with the lid part. Bigger version here I created a revolve object as the main volume for the lid. And just wanted to carve away 2 holes with a boolean operation. But I'm not getting a good result. The Negative/hole part is a loft NURBS and the Main volume is a revolve object. When I render I'm loosing the vertical walls. I created a simpler version with a cylinder to test my idea and it works ok there. Any idea why I'm not getting the expected result? Thanks in advance. __________________ Fernando J. Velarde www.velarde.com share quote

You would need to perform the boole on a closed volume. __________________ The views expressed in this post are by no means the opinion of those making the post or of any one person in particular. share quote

Hello Patrick.

Thanks for the quick response. I believe it is closed. I have a bottom. Or am I misunderstanding what you mean?

Thanks!

Then, when you boole the cutout there will be thickness and solidity. OR, If you want the shelf opening, put the same texture on the boole object so it renders the inner profile.
