It is really quite painful to route tubes and pipes with the current UI workflow of using the space bar to flip the directional arrows at each and every routing point, only to have that same directional arrow suddenly flip opposite in the fraction of a second before you mouse click to enter your selection. This is lethal, in that once you select a routing point, there is no "flip direction" command afterward that would quickly remedy this issue. So the only option left for the design engineer is to delete that particular pipe run and start all over again. TIME CONSUMING!!! Even using the point snap and directional snap selections has no noticeable effect on keeping Inventor from suddenly switching the directional arrow opposite just as the user mouse clicks on a given routing point. This has got to be fixed soon, or else just get rid of the pipe & tube add-on. It is virtually useless as it anyway with this ridiculous behavior.
