I need a AutoCAD Recap expert – pipes.

I need someone to import an XYZ point cloud file of a pipeline into RECAP and give it a surface. This is the host pipe. Then find centerline. Then create a smaller cross section version of the shape and pull a length (say 8 ft) of it through the host pipe.
I am trying to do something like this, called virtual mandrel. Where you pull a pipe through another pipe and look for interferences: https://redzone.com/nr/virtual-mandrel-increasing-roi-with-lidar-inspection/
