I tried to view the attached file that contain only lines in the https://3dviewer.net/ , but it did not take it … it looks like it needs more than lines … 3D objects …
Thank You Morteza … yes I had to create pipes which are 3D solids and then be able to see the solid entities in 3D … appreciate your feedback … Thank You
