Hello! I’m very sorry if this problem has already been resolved, but I didn’t manage to find the answer. I need to draw (generate?) a large plane that passes through the three points (markups) as depicted in this photoshopped example: [Slicer] Thank you very much for your help!

You can create a plane polydata using VTK and set it as polydata of a model node. Probably 6-8 lines of Python code. Check out Slicer script repository for examples. https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository#Set_slice_position_and_orientation_from_3_markup_fiducials There a…

Did you resolve it and I am very interesting for that even I can do it easily in Mimics

It’s very easy to define a plane using markups (the linked example shows how to create a sphere based on markups). The question is what to do with it once you have it. Just display the plane, or cut models with it, or use it as a reference for measurements, …?

what I went to do usually in Mimics just to cut a model, define a point or a midline for my model. I think it is important we can extend the plane created by three makeups

Thank you very much for the prompt answer! The code with shpere looks perfect in this situation, except I don’t have enough coding experience to modify it myself. If you could advise me on how to change figure from the spehere to the plane (rectangle?) and define two additional coordinate points fro…

[image] George: and look at the diseased arterial segment - if it is situated above or below the plane. Would something like in the attachement be sufficient ? It’s much simpler to do for locating a diseased artery. Your use case context is yet not clear. [Screenshot]

Hi, I’d be interested to know how to cut a model above a plane defined by markup. thank you

I’ve added a short example to the script repository that positions the red slice viewer to fit on first 3 points of F markup fiducial list: Documentation/Nightly/ScriptRepository - Slicer Wiki You can clip a model using a slice view’s plane using EasyClip extension . If you segment the structure us…

Hi and thanks for the code. I tried it and it’s very usefull to segment just one side of the skull and make the model Finally what I’d like to obtain is the mirror of this model but when I use the mirror in surface toolbox I can’t choose the mirror plane that I whant (the same than for the segment…
