“Every block of stone has a statue inside it and it is the task of the sculptor to discover it.”- Michelangelo
When you create a curve, you enable it to have the potential to be extruded out into space. Michelangelo understood this process very early on and with it was able to draw the initial carving curves on his raw materials. This basic idea behind extrusions is a critical principle to being able to create forms and, more importantly, come back and edit them. Have questions? Leave them in the comments below!
