AutoCAD 2015 (Vanilla) had a great plugin that would let you select parts of a pointcloud, and it would recognize cylinders and create solids. Well it's not available after 2015. But in 2017 there is a new Autodesk tool PCEXTRACTCENTERLINE ! when you use it, you can see it recognizes the cylinder and creates a centerline. I am sure there isn't a way in VBA (what I am most comfortable with) But is there a way I can use PCEXTRACTCENTERLINE in .net to leave the cylinder that autocad temporary creates? see attached photo (transparent purple)
You might try creating a DrawableOverrule targeting the Solid3d class, and see what pops up in WorldDraw() and ViewportDraw(). If you find the cylinder, you may be able to Clone() it.
