The following 10 steps show how obtain a scallop sea-shell (or something similar to it!):
- Add axis - Add lines like this (use front view):z __ ... | ... __ .__| |__| +---x |__| |__.
-130 .... 0 .... 130
- Invoke the extrude req: to length 200 scale x 0.5 sections 10 - Add a primitive tube: radius 120 - Scale down the tube: 70% only y (shift-y) - Adjust the tube position to cut the extruded shape like this: _________ / \ /\ /\ top view /__\_______/__\
| | cutted cutted
- Select extruded shape then tube and slice them - Delete resulting objs except the 2 'planes' ('planes' should be part.2 and part.3): _________ part.2 /---------\
and this top view _________ / \ part.3 / \ \_ _/ ---------
- Select first part.2 and then part.3, join them - Invoke mold req and conform to sphere: sphere radius 100 object radius 320
