Cannot cut into body without a large distance

[zghan2005]

Why am I unable to cut into this body unless i use a large distance?

At -10mm it seems to cut directly through the body

But at -1mm it tries to create a new body. And yes I've tried manually changing the operation to "Cut" and it said there's no body that intersects to cut.

 

 I'm 99% sure that the sketch is made directly on the surface of the body. Or maybe I'm wrong, what should I do here? I've attached my project file.

There is no rectangular profile in that file.

The triangle works as expected.

Might help...

If you try to put a rectangle anywhere on the surface in the "Texts" sketch or create a new sketch directly on it, you should see the same issue.

Hi,

If you create a body with “Boundary Fill” you can also add the desired extrusion.
Perhaps    @Phil.E  could explain why this is the case.

Sorry I don't follow, will creating a body with boundary fill somehow allow me to cut into this body? How would I do that?

My ultimate goal is to put a bunch of text around the circle, by cutting into the body and then extruding it again to embed it into the disc, allowing me to assign a different color in my 3d printing software.

So will this solution work for text too?

I can make the cut, only if I push it past 4mm

Short of 4mm the operation finds no body to cut.

Suspect it is the converted mesh body.  Quicker to make it from scratch.

@Phil.E one for the bucket. (OP file)

Might help...

I'm not sure how to make this from scratch, I need it to have the same exact dimensions and ridges on the inside since this is one part of a larger build.

In the screencast I have limited the process to a section in order to shorten the computing time.

This is a strange one. It only fails when the cut starts on the converted mesh body, and only the body. If a sketch shape is partially on the body, and partially in space, it behaves as expected entirely. Once the extrude passes into space at 4mm depth it computes correctly.

This appears to be a problem with the converted mesh body because it doesn't do this with scratch built solids. (report FUS-163892)
