Hi Niru C,
This contribution is devoted to the visualisation of 3D images. For your problem, I would suggest trying my other contributions geom3d (#24484) and geom2d (#7844), in particular functions intersectPlaneMesh, and polygonLength.

Slicer for exploring 3D images (grayscale, color or vectorial) through planar or 3D slices.
I have this 3D point-cloud which I made into a triangulation mesh (~4500 points) using the ball-pivot algorithm. I want to find the perimeter of an outline formed from intersection of this 3D mesh and a plane parallel to XY plane say at different Z values. Can I do this in this program ? What will be your suggestion?
