Flat plane over x-y-z (not x-y only)

roland_demmerich

Hello, everyone,

I currently have a problem with my drawing and haven't been able to find a solution for days.

The problem is: My 3D printer cannot print the part like this.

I would therefore like to have a flat surface on the corner so that I can "lay it flat on the printer".

Unfortunately, I didn't find any help level or something similar - I'm really grateful for every hint.

I hope the picture explains it a little better.

The red area should lie flat on my printer.

But I just don't manage to define an "auxiliary plane" (?) with 45° to then remove it.

Onshape doesn't have a built-in corner chamfer. However, there are lots of ways to construct one. Here are several examples. There might also be some custom Featurescripts floating around that will do this for you.

1. Chamfer adjacent edges then delete the unwanted edge chamfers faces to leave just the corner.
2. Loft cut between a sketched line and point.
3. If you have a cubic shape (which you do), you can create a parallel plane using 3 points and then use a split/delete or extruded cut.
4. Create a plane using line-angle (angle = atan(sqrt(2)) and then use a split/delete or extruded cut.

Found this Featurescript written by @Jake_Rosenfeld a couple years ago.
