I have some confusion with the “Move” tool within Rhino and why it is causing a mesh that initially has no problems to suddenly generate a mesh with 20 extremely short edges.
For a bit more detail about my process, I import an .STL model of a coronary stent with 610108 polygons, 633319 vertices into Rhino. An initial mesh check from the Mesh repair wizard tool says “This is a good mesh”. There is no degenerate faces, non-manifold edges, naked edges, etc.
Next, I create a multiple point object in space, followed by a polyline that runs through the points (red line in the images below). An axis is also generated for the stent model. The move tool is used to align an end point of the stent axis with an end point of the polyline. The mesh object moves to the correct location, however, after further inspection with the mesh repair wizard, I am given an error saying “this is a bad mesh” and “Mesh has 20 extremely short edges”. The number of polygons and edges remains the same as the initial mesh.
Any thoughts as to why this might be happening? I am hoping to rotate the stent to better align with the polyline and then perform a flow along curve to bend the stent.
I greatly appreciate any advice or ideas of how to correct/avoid this obstacle.
