Greetings, I'm just finally taking time to sit down with 3D Coat since buying it last December and not only am I finding it to be an incredibly worthwhile purchase, I think it will take over as my main modeling application. My initial desire for 3D Coat was for 3D printing/rapid prototyping. I found one thread on Scale but I just want to make sure I understand the workflow correctly. I'm having trouble creating primitives with specific dimensions. For example, if I want to create a cylinder with a 2mm diameter and drill that through a model for a screw hole, how do I specify that? Or, am I doing this process wrong? Should I create my base mesh(es) in my traditional modeling application, then bring that into 3D Coat for additional detailing, boolean operations, and retopo, then back out? If this is the answer that's definitely suitable, I'm just trying to figure out the most effective process. Thank you.
