How to make a cuboid tube between two points

Community

When I use Segment Editor, I can make a tube through Draw tube, but what should I do if I need to make a cuboid tube between two points?

Can you draw a sketch of what exactly you would like to achieve?

There are many options how to achieve this. For example, using Markups to model module:

Would you prefer to draw a segmentation or just display a tool trajectory?

I’m just curious, Why do you need rectangular cross-section? All the drills, catheters, etc. have circular cross section.

All the tools for creating such tool guides fully automatically (using a small Python scripted module) is already available in Slicer.

To create a model, probably the easiest is to create the stick first, for example by running this command:

slicer.modules.createmodels.logic().CreateCube(20,30,120)

then apply a transform to position it, and import it into the segmentation.

You can find examples for most operations in the script repository.
