New to using 3D slicer and have followed the cardiac segmentation video and had a question regarding export of the segments into STL. It seems that when one goes to export each segment as a model they are exported as there own segment (meaning 8 stl files for 8 segments). Is there anyway to combine …

Operating system:Windows 7 Slicer version:Slicer4.9.0 Expected behavior: stl file for the merged model Actual behavior:error in merging the two segment model Hi, I am working with Slicer4.9.0. I want to generate stl for a sample having two regions. I could generate stl for both regions individ…

[image] Anis: I am working with Slicer4.9.0. Use latest stable version (Slicer-4.10.1) or later. [image] Anis: Gmsh which I use for further mesh refinement You can use SegmentMesher extension to create high-quality multi-material meshes directly in Slicer. [image] Anis: I don’t h…

Hi Andras, I want to use gmsh within slicer. The problem I am having is I am unable to view the vtk files generated by using gmsh and meshio. Also another problem is that I create a surface model node. how can I use this surface model node as input to gmsh. any suggestions? Also if I use the segm…

[image] Saima: if I use the segment mesher I found it generates a mesh from label maps but the mesh is not refined. thats Why I now jumped to gmsh. Any suggestions? What do you mean by “not refined”? By default mesh generation is set up to be very quick and generate a course mesh. You can adj…

Sorry I mean fine mesh. How can I get a fine mesh using segment mesher with only one label map. Thank you Regards, Saima Safdar

See this tutorial: https://github.com/lassoan/SlicerSegmentMesher#tutorial . Near the end there is a step to create a finer mesh.

Hi Andras, I checked with multiple values for scale but it always give me a mesh with some external elements which are not in the label map in segmentation. [image] For example see in the fig above. the label map is ok but mesh is not ok. why am i getting the mesh like this and not exactly what …

You can add a box-shaped segment around the brain (e.g., using Scissors effect, with appropriate masking settings). You can then extract sub-meshes by thresholding based on material ID cell scalar.

Latest nightly version of Slicer has a dedicated file export feature. You have the option of saving as merged STL (all segments merged into a single mesh) or OBJ (single file, segments are different objects). See details here:
