how to edit 2 parts at the same time in assembly ? I want to extrude a surface from 1st part to the other part(2nd part), and I can only edit one. Thanks for help
You can not edit two parts at the same time, what it sounds like is you need to create a new part in the assy.
Edit one of the Parts within the Assembly. When creating the Extruded Boss/Base, select "Up to Surface" from the End Condition drop-down, and you should be able to select the surface of the second Part.
That's what I have by creating the Extruded Boss/Base, selecting "Up to Surface" I want to connent these 2 parts in assembly
In your extrude choose to select a 'direction vector' and then choose an axis that runs down the tube (the temporary axis would be fine and then you won't have to create one).
This should join these two pipes together.
