What is the protocol for extruding objects along paths. I cannot find any user-friendly assistance in the manual. I am not used to the CAD geometry approach as I have more experience with the older Finite Element packages, where the geometry was constructed then meshed. Extrusion, mirroring etc were intuitive.
Also, I constructed a nurbs path in the shape of a wheel section, and constructed what I thought was going to be a separate nurbs circle, perpendicular to the plane of the wheel section, running through one end of the section path. When I tried to perform the extrusion, using E, and transform rotate, there appeared to be no control over the transformation re axis. When I selected the nurbs circle, I found that it had merged with the wheel section. 1) How do I separate them, and 2) Can I perform the extrusion using this method?
I am using v2.76 on a fairly quick XP SP3 32bit 3.3GHz Pentium 2 core and a GeForce 6200, with adequate ram and hdd.
