Hello Hoang, 

In SpaceClaim, you can change the coordinate system for the cross section by using the Move tool. There is an Anchor option with the Move tool that helps position it on the new coordinate system and align its axes with that system.

Please refer the article In SpaceClaim, how can I orient the Move Tool to my new coordinate system so that I can move objects according to the new coordinates? - Ansys Knowledge for more infromation. 

Cylindrical coordinate system is not possible currently.
