I am currently working on a button design that requires a crown on its top surface, see pic below. The highest point is 0.30 MM, ideally from its x-sectional center of gravity. What is the best way to:

1. locate the C.G.

2. model the dome for its top surface.

Creo 2.0 attached.

0. make extrude solid

1. get CG from mass properties

2. locate CSYS with CG parameters

3. create point .03" above over CG

4. intersect desired dome curve

5. generate edge sketches (2)

6. create boundary blend and manipulate the joining points.

7. create surface from top surface

8. merge surfaces

9. solidify

Steps 7-8 made for cleaner edges.

Probably 10 more ways to do this but that's what I did.

sorry, missed the 0.3mm... Some more tweaks on this one.

Hello, you could also consider using some old pro-e features burried deep down in the software, Radius dome & Section dome. There is a config option allow_anatomic_features which allow the use of these, but they are still hidden. You can access them by searching in the top right hand corner for commands that are not in the ribbon. They might not give you the required geometry, but they are an option all the same.
