Boolean Problem

 09 September 2012 velarde Graphic Designer   portfolio Fernando Velarde Branding Strategy & Design Monterrey, Mexico Boolean Problem Hello Everybody: Hope someone can point me in the right direction to fix this. 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

Thanks! __________________ Fernando J. Velarde www.velarde.com share quote

 09 September 2012 vid2k2 Expert When you lathe / revolve the cap you should create an outline so that thickness is built into the shape. 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. Edit: Detailed lid __________________ David iMac 3.06 ghz Intel Core 2 Duo / 16 GB / OS 10.13.4 / C4D StudioR12 / CS6 Last edited by vid2k2 : 09 September 2012 at 03:59 PM. share quote
