Can you give me three different methods to generate a solid cylinder using catia?

1. Revolve of a rectangle sketch

2. Extrusion a circle sketch

3. Knitting of surfaces of surface revolute and planar side surfaces to form a solid.

Hello, there is a forth method using imagine and shape module in CATIA (this is else than revolving a line about a center, extrusion of a circle or stitching surface revolutes with top and bottom planner surface of the shape of a circle.) 

You can check a video illustrating this here, I love it : http://www.youtube.com/watch?v=5_qw_ne-Caw 

Enjoy :)

a) Extrude a circle

b) Revolve a rectangle

c) Extude a Rectangle. Give fillet on all4 edges with R=(width)/2

1. Create cross section circular profile and extrude it's length.

2. Revolve a rectangular profile

1.By using Shaft operation

2.By Using Pad operatoin on circular closed profile

3.By using any raw solid model we can create cylindrical profile from it by pocket operation

1- Extrude 

2- Revolve

3- Extude then fillet
