Noob question: How to model a jagged cone
I want to show you a technique I used recently in one of my models - Pi fruit bowl. It's quite simple.
First I extrude a cylinder, then wrap text or line and finally cut-revolve it in the desired shape - e.g. bowl, glass, cone.
Here is a step by step guide and the SW 2014 file.
I hope it's helpful.
Surface extrude a cylinder with a desired diameter (200 mm in my case)
Wrap a sketch around the cylinder. The sketch has to be closed contour. The only dimension here is an equation for the length of a circle pi (3,14)*diameter or pi*200 mm in my case. The cylinder is now divided in two parts (top and bottom)
Surface Offset the bottom part with 0 mm, then thicken it 20-30 mm.
Do a revolve cut with the shown sketch. You can change the angle and thickness of the model as you like.
Add fillets, engrave text and etc.
Here is the final version of my model with the feature tree shown.
