Hi!
At first I need to say that I'm a newie on this software, I work as concept designer/modeler and I'm familiar with other software packages.
I have search any similar thread without results, if it exists would be great to have the link here ;)
I'm having some random error with boolean difference, doing the same operation as you can see in the attachment.
I'm using the same resource to create surface details, and doing the same operation that worked some steps ago(with the same objects) it doesn't work after.
I've tried to boolean diff with simpler source objects and looks like the big geometry(the one I'm adding surface details) doesn't allow to do anymore boolean diff operations(diff only creates holes where I can see inside geometry).
Sorry about my crappy english :S
