Hi, I am wondering if anyone has been able to implement a square/cube brush for “Paint” in “Segmentation Editor”. Thanks.

You can kind of already do this using the scissors tool. Use “Fill Inside”, “Rectangle”, and “Symmetric”, and pick how “thick” you want the painted area to be.

I have wanted in the past a cylindrical brush and it would be great if its shape could geodesically warp an existing segment

You can do a cylindrical operation using scissors with symmetric as well, and even draw arbitrary shapes.

I’m not sure what you mean by “geodesically warp an existing segment”.

I have requested this before because I was used to Mimics having both circle and square!
