Operating system: Win 10 64 Bit Slicer version: 4.7 Nightly Background: Undercuts are important in dental CAD because for two rigidly mating objects (for example teeth and an appliance), a path of insertion is necessary or else the parts will bind. This is also useful in many other applications …

This sounds like a good approach. You may use Crop Volume module (even from your own module, programmatically) to create a reference volume with any size, axis directions (you can rotate the ROI by applying a transform to it), and any resolution. You may use Segmentations module to convert between …

Thanks for the update. Nice progress. A couple of suggestions: It seems that you use some very old template for your extension. Download the latest nightly build of Slicer (it works well and there are many bugfixes and improvements compared to the latest stable version) and use its Extension Wizar…

Re: Extension Wizard. I have been following tutorial from Sonia Pujol and Steve Pieper for my Module Template. I will use the wizard and re-package once I get the initial workflow Re Git: Absolutely. Most of my projects are github repos. In fact I just used Gist to get a quick show and tell …

I used the Extension Wizard to generate cmakelists.txt, a png file. I have uploaded project to a github directory. It is up to date with current code as seen in the video below. https://github.com/patmo141/SlicerModelUndercuts Initial workflow is very close! I seem to have a problem with …

It looks really nice! I think the only step you miss is calling modelLabelMap.Modified() after you’ve modified the modelLabelMap voxels using numpy (around line 175).

Another small suggestion: instead of switching between Segmentations and Models modules to show/hide segments and models and export segment to model - you can use the Data module for all this. Click on the eye icon to show/hide a node. Right-click on a segmentation node to export to model.

[image] patmo141: I used the Extension Wizard to generate cmakelists.txt, a png file Use the Extension wizard to create a complete skeleton for your extension and your module (adding just a CMakeListst.txt is not enough; you’ll need a separate subdirectory for your module, within that a Resou…
