Are situations with 1,2,3... bubbles.
I parameterized everything in sketch,also the length will be modify and what i want in plus is to add bubble or take out.
I managed to put parameters for bubble radius, diameter, length,I did not succeed to add or subtract more bubbles
- number of bubbles (can be 1,2,3,....n)
- overall length (starting from 50mm to 300,400mm)
- pitch (can be different from case to case)
- bubble radius (can be different from case to case)
- groove radius(can be different from case to case)
- outside diameter(can be different from case to case)
Bellow you can see two situations
Still not enough information, but here is a different approach to your problem: First, make one "bubble" and then use a Pattern for the others. Then add a Fillet where the Pattern intersects the center shaft.
The Parameters: (first 3 are inputs, and other 2 are calculated)
I hope this is enough to get you started based on your definitions.
*This method does NOT work with only 1 bubble since it uses a Pattern
*Two Planes are only to verify the overall length
*The Assembly command allows using a Fillet where Body.2 intersects Shaft.1
