I have an existing part that I made using my standard methods. Now I want to remove material from the top surface to make it more streamlined. However, the only way I can think to generate this geometry is to use the flex command. This is not an option because it would destroy my model tree.

Below is the goal surface.
How can I mimic that surface by removing material from a boss extrude that is already in the flexed shape?


Thanks for taking a look.

Why do you say that the flex feature destroys your model tree?

Create a 3D sketch with two guidelines for a swept cut. Better to create the shape direct with a lofted boss.

In my real part I have a lot of other features that are constructed on top of a boss extrude. If I were to replace the boss with the flex then all those features would need to be redone. If there were an easy way to apply it at the end of the tree that would be awesome.

3d sketches always screw me over, I will give it a try.

Another option would be to create a surface defining your top face and using Boss-Extrude with Up to Surface end condition.

This model would work well with Sheet Metal features...

I ended up going with a combo of your suggestions. I used a 3d sketch to create a surface sweep and then a cut with surface. The result looks great. Thanks everyone for your ideas.
