Not sphere shaped lowering?

chriss_ko

Hi *,

I need some help with a lowering into a part. Excuse my bad English, I do not know all 3D desighn related terms in English, but I will try my best.

I have a body, (flat, squared 5mm thick,) I need now a lowering in that body which needs to be sphere(ish) shaped but with different angels and dimensions in the two axes. So I can not create a ball and substitute it from the part. And ideas how I can create a lowering which is not perfectly round?

You see that X1|2 and Y1|2 has a different height on Z too. So I need a kind of a mesh which lays on the Y and X points. The body should direct to left when you look at my picture. I can share the doc if needed but I think that has no value.

I bit background: I want to glue a 3D printed part to the back at my curved monitor to place some things on it. Tee monitor is curved on the back into Z and X. (Yes X and Y in my drawing)

Andy ideas? 

Cheers, Chriss

Have you considered creating a set of constrained reference points (measured from the back of you monitor housing) and put a spline through them?

Hi, I would sweep a surface. The profile would be the curvature (x1/x2) and the path would be the curvature y1/y2 (or the other way round). This should create the profile you want.

I have, indeed.. But I do not have and idea how I can conenct the splines than to make a surface out of it.

make sure you constrain (pierce) the two splines. like here...
