The final (and the most tricky) step is the conversion from STL to CAD format and here FreeCAD can help. Both STEP and IGES are worthless as far as conveying any information past the dumb solid. Then the STL model has to be post-processed and again there are a few interesting free programs with Meshmixer and MeshLab being likely the best ones. ![]() ![]() My favorite one is 3DSlicer but I've also heard about Seg3D. Fortunately, there are some powerful open-source solutions. This is a quick demo of how to install and get started with Mesh enabler add-on for Inventor. The biggest issues were related to the fact that the conversion of STL file to CAD model leaves a lot of unnecessary surfaces We discussed this topic recently here: Ī lot depends on the software used to obtain 3D model (STL) from DICOM data. I have tried some Add-Ins like Sycodes STLImport and Sycodes software called Mesh To Solid to get those mesh files open and I can open those 'converted' files in Inventor, but those are only some kind of surfaces called Composite or Surface which consist of tiny triangles. STL) to editable B-Rep feature objects (for Inventor 2022-2016, subsc.) Download the file and open it in the respective application, or copy it as instructed (true). I used to do such DICOM (or 3D scan) -> CAD model conversion in the past, before I knew FreeCAD and had to use the Mesh Enabler plug-in in Inventor which appeared to be the only solution available for students. Inventor Mesh Enabler - convert 3D meshes (e.g. ![]() This topic is quite complex and difficult to realize properly, especially without very advanced commercial software.
