Dynamic component: Circle segment by component options (dialog box)

Hello everybody,

on the left there is the SketchUp working model in standard color. It is a dynamic model! I tried to modify
the model for to have in result the right (yellow) model as a functional dynamic model.
After a few days without a working result I would like to ask if someone could help me with my sketchup model on the right (yellow). The biggest problem is to receive an empty area in the middle of the circle.

I would like to change all dimensions with double bracket () by a dialog box.
So in result thickness of material, angle and so on can be changed and flange moves
according the angle given.

Any help is welcome! Thank you!

(Sorry about my weak language. I am native german speaker.)

Best regards

Bernhard

Right!
Simply duplicating the left dynamic model in order to get an outer radius and an inner radius can be done quickly. But then I did not succeed in deleting the inner cake section and at the same time getting the front of the pipe section closed! But Sketchup is evolving and certainly won’t want to lag behind other CAD programs … I hope so much for a solution.
