Pipeflow animation macro for Inventor

This video demonstrates my pipeflow macro i build for Autodesk Inventor to visualise a flow in a pipe system. Just for presentation purposes. It was written in VBA, all parts are native Inventor. The entire route, direction, speed and color a customizable. I made this as a final exam for my ACE Mechanical Designer study at CAD College Nijmegen (TEC).
