Hi Kixum,

Well I have been trying out the  "Boolean" manouvre in my quest to make a hole in the car side..........Yep...   am now ready for some of your Magical weird tips.lol

But what I found ( and everybody knows this already I suppose ) is that booleans seem to work fine with Primitives....drop a cube through a plane perfect square....a cylinder through a sphere  leaves neat hole. Even create text drop through a cube same nice cut or engrave

 The only exception I found was trying to cut through the side of a cylinder with text.....this it didnot like..it performed the cut but it left several artifacs along the way.as you can see above.

How do you clean up this ?

and make your uv maps fresh over.

Cheers Blueblott
