I guess a noobie question, if so please point me towards where I can find enlightenment :

While drawing the routing of a pipe when one makes an angle for a bend (may it be 90° - 45° or whatever the situation warrants) the 3D sketch creates virtual sharp points. This points usually end up underneath the dimension line of the bend.

The question : Is there a way to prevent those points to be moved?

1) Sometimes when the pipes are angled in reference to the x-y and z plane as well as to each other it would be convinient to use those points instead of having to create 'construction lines' or additional planes.

2) even if just to be able to place a dimension between, let's say, a pipe route part in the x-y plane and a pipe route in the x-z plane without making extra planes or lines

3) I would suspect that having a virtual point that doesn't seem to be constrained by the sketch would be cause more problems. Am I looking at it wrongly or do others have an issue with it as well but just learnt to life with it?
