Hello everyone, I’m trying to reduce the spacing using cropped volume in order to create very thin walls with a uniform thickness, but the spacing of the cropped volume is again at 0.2826 mm. So it makes no difference whether I use cropped volume or not. With a required wall thickness of 0.2 mm, t…

I have right-clicked on Model and clicked on Convert model to segmentation node, but I can’t cut with the scissors [model segmentation]

Yo don’t convert this thin-shell model to segmentation node. You cannot represent this thin smooth shell as a binary labelmap. If you could, then you would have chosen option B. Instead, you need to do the conversion to shell as a very last step of the segment editing. After that, you can only edit …

Hello Mr. Lasso, after I had inserted the Python codes from your script, the yellow model got. I have hidden the inside of the model and obtained the desired image in the 2-D representation. Now it’s time to cut the ends. Which module is the best way to do this? I would like to know how to save the…

Hello Mr. Lasso, I was looking for a suitable example to explain the Dynamic Modeler a bit more precisely. I came across this video: [3D Slicer: Dynamic Modeler - Parametric Surface Editing for Biomedical Applications] Do I need to put MarkupsPlane as in this video? In your screenshot…

Yes, you need to specify a cutting plane to cut the mesh. I would recommend to use a markups plane, defined by clicking 3 points around the vessel tip (you can adjust position/orientation by enabling interaction handles).

I have now added a markups plane on both ends but only the model can be hidden. [plane cut (2)] [plane cut (3)]

Can you please tell me how to save the new model as STL. Do I need to convert it first? [stl file]

See how to save data in the documentation: https://slicer.readthedocs.io/en/latest/user_guide/data_loading_and_saving.html#non-dicom-data

Dear Mr Lasso, I have tried to apply the principle with the Markup Planes to more complex vessel models with several openings, but I have the problem that the cut plane is not limited to the red field/window, but runs completely through the axis and cuts out other segments I need. ( see figure) […

With a single plane, tip of the other vessel segment is clipped:

By adding a second plane and choosing intersection operation, we can prevent second clipping:
