Sculpting Questions...

No.1: How to sculpt in a straight line?
No.2: Can the “Brush Circle” be “on” a model like zbrush?
No.3: How can I cut a hole?
Please answer my questions, I’m dying for answers…

No.1: How to sculpt in a straight line?
Smooth Stroke option or use a texture with mask brush to specify a straight line

No.2: Can the “Brush Circle” be “on” a model like zbrush?
No way

No.3: How can I cut a hole?
Boolean modifier

On his GSOC 2011, Jason Wilkins on a follow up to Nicholas Bishop GSOC 2010 had impleemented the “brush on surface” function, along many other usefull things.

Unfortunately it never made it into Blender releases. We can only hope one day those lost features will.

Thanks for the answers (especiallyRichard…), but, why not implemented? What’s the problem? It would be really great, it’s a bit of confusing now :(…
