Workflow: Lip and groove for 3d printing?

Hi. I was wondering about how to go about creating this in Zbrush. Say I have a torso for a character that is just a shell.

This is what I’m after: https://hawkridgesys.com/media/content/blog/lipgroove1.png

One way is to split the body into two halves so that there is a clean polyloop along the split faces on either side. The use the Zmodeler brush to insert an edgeloop down the middle of the polyloop and Qmesh to push/pull the respective loops on each of the two bodies to make the rabbet joint.

The difficult part might be getting the clean polyloop after splitting the body in half. Slice Curve followed by Zmodeler : Edge Action Bridge Two Holes might give the desired result. Might need a little clean up in tightly curving areas where a 1:1 mapping of outer and inner polygons doesn’t exist.

Another possibility it to duplicate the model and use the Knife Curve brush to cut away one half of the model. It will leave a clean face on the cut face. Then create an edge down this face with the ZModeler Slice brush or with the Slice Curve brush. QMesh on one of the sliced face to the desired height. Then boolean subtract this half from the full model to leave two pieces with the desire rabbet joint.

Good Luck.

Hi and thank you.
Sorry, I forgot about this for two years!
But I just got back into it and trying some things now.
The slice curve does give me a solid cut with polygroups that I can zremesh and it will give me a clean loop around. Sadly though, I can’t replicate this cut on the other half as it will just remove the other half.
I’ve tried a few things with live boolean, and probably will go with that.

Thanks so much for your suggestions. and sorry for the late reply.
