I am making a point suction device for a lab environment.
The device consists of a number of pipes assembled by some elbow joints, and a start bushing and some various ends.
I have made it so that it follow a path giving the length and the angles of the entire device. in all joints is an elbow joint.
The elbow joint is a round cup and the pipes are sticking into this. I haven't made any holes for the pipes in the joints as this would unnecessarily complicate things a whole lot.
To handle the pipes Z position (the pipes is offset to each other by a little more than the double of their radius). I have made a macro that put the pipe alternately on each side of the path,by checking if the segment is even or uneven.
Now to the problem.
Since the elbow joints are round, I need to stick the pipes into the joints center, - otherwise there will be gaps. I have set the bevel to none - so that it doesn't extend the pipes, which especially will be bad where the angle between the pipes is very narrow.
I have given the pipes padding values for left and right, so that they extend into the elbow joint . BUT it doesn't do it at the end segments and the distance into the elbow joint varies???!!!
What do I do wrong and are there a way to get around this?
I have attached some screendumps so you can see my setup.
If you look at the front view - you can see the problem with the pipes.
