Hi guys,

I want to create a relation between the tube and the dilator so that when I insert the dilator (3.5mm diameter) inside the tube (3mm internal diameter and 4mm outer), the internal 3mm diameter expands gradually to 3.5 and the outer to 4.5.

I already set a relation of 0.5mm distance on the tube.

How do I make that connection between the dilator and the tube so it expands what I "drag" it inside (while touching I mean)?

Thanks!
