How to make a odd-shaped "bowl" or how to make a concave face on an odd shape

alec.w.penland — Tue, 07 May 2019 03:49:46 GMT

Looking to turn my object into the attached picture. I can't figure out how to smoothly loft into the face. It's supposed to be .83mm deep at it's deepest point.

I am waiting til after the loft to fillet all the edges.

Whether there are flat points in the middle or not is unknown, just looking to make it relative.

Hi,

just to show the principle, the example was created in < 5 minutes.

concave face

An optimization can be carried out e.g. by a different division of the areas.

I like this method. The only thing I would differently is to Modify -> Replace Face instead of the split body. But that's just personal taste I guess.

Here is my method. I used a couple of lines to define the depression, but you can do it with whatever you think will create the shape that you want. I apologize for the length. I should have been able to do it in half the time, but I had a few short distractions in my office while making the recording.

For example, you could instead use an offset for the Patch's inner rail. It might be a little more uniform this way.

Hi Alec,

here is the button with concave face:
concave face (sculpted)

You can still optimize the shape by activating and editing the sculpting face.

Guenther, would it be possible to do this parametrically? Doing concave using forms like this could be very useful for me if I could have a parameter for the concave depth that I could change in the Parameters menu.

Thanks for the solution, BTW it seems that I see you helping on every forum post I see around here.

Thanks!

No. T-Splines (forms) at this time are purely direct modeled objects.
