Forum thread

• Original thread: [Feature Request] No. 6439 - DICOM to CAD workbench

Idea description

Ability to import DICOM files with CAD data (STL/STEP), extract data in to FreeCAD to further modify for whatever purpose. This idea was inspired by multiple forum threads and some social media interactions:

• How to build a Jaw (forum thread)
• mesh to surface, how to do? (forum thread)
• stl to solid, works and not, why? (forum thread)
• https://twitter.com/FreeCADNews/status/1496504162560925698
• Contributing to Orthanc (FreeCAD is mentioned on this page)

This ticket has several parts to it:

1. it's related to Allow editing of multiple sketches at the same time #5580 which is a feature request to have more than 2 or more viewports open simultaneously
2. the ability to parse out CAD data from DICOM files (this is also possible through some open source toolchain like
   2a. Use Orthanc server API to pull CAD data out of DICOM and import directly in to FC
   2b. Use MITK in some form or fashion as above
   2c. Use workflows discussed on this page

Anything else?

Other projects of interest:

• Ginkgo CADx (LGPLv3) is an advanced DICOM viewer and dicomizer that can also be used to convert png, jpeg, bmp, pdf, tiff to DICOM files. Project is abandoned.

Just wanted to keep y'all in the loop on this (feel free to unsubscribe, or I can remove you if you deem that necessary). But we're hoping to collaborate if possible.

@jodogne keep us in the loop, if you don't mind, about orthanc features oriented in the direction of this ticket.

It would be good to know if there are any Blender/Inkscape/Gimp/MeshLab etc... devs that would be interested in collaborating?

@jodogne How's progress on orthanc going ?

@jodogne How's progress on orthanc going ?

I will supervise a student that will (among other) work on the Encapsulated STL IOD during academic year 2022-2023 in the context of his Master's thesis at UCLouvain.

Great news! Any implications on a orthanc->freecad workflow ?

We'll see, this will depend upon the student's progress.

There's a patch for GIMP to port the existing plugin to Grassroots DICOM (GDCM) library. But it's from a new contributor, I don't know him at all. And I'm not sure what collaboration would look like. Thoughts?
