Route line question

Hi all:

Using SW2007 SP5. I am adding route lines to an exploded assembly
that contains cylindrical parts welded to a flat plate that is
featureless. I would like for the route lines to terminate where the
axis of the cylinder intersects the flat face. However, the Route
line tool extends the line to the point on the flat face that I click,
jogging along other axes as necessary. I have checked the help, and
tried clearing the Along XYZ option, but have not found a way to get
this to work. My workaround has been to manually stretch the route
line until it looks like it touches the face. This works, but is time
consuming. What am I missing?

Thanks in advance,
John.

 

Don't pick the face. Pick the edge of the cylinder.

 

You can edit route lines just like any other 3D sketch. That means
you can also add constraints. You can make the route line endpoint
coincident with the end face of the fastener.
