mitering tubes at angles

[dewme5]

below is copied over from the drawing forum. I posted it in the wrong forum and I am moving it here.

I'm not sure what way I should be going at this. I'm trying to
understand the way to intersect tubes. With design-engine's help, I've
been able to create fish mouths. What's wrong now, seems so simple
that I don't understand why I'm having such a hard time.

I
am trying to intersect two tubes at 90deg with a straight 45deg cut on
each end. In the picture attached, I need the 3 tubes separate. Right
now, I sketched the shape, and then >insert >sweep >thin
protrusion.

I've tried using the same method for the fishmouth,
using an offset, and then solidify, and I can not get it to work
successfully.

If I could create a long sweep, and then just
move the sections to seperate files using a skeleton, that would be
great, but I don't know the right direction to look in, or I'm sure a
search would have given me what I need.

I have a skeleton model giving the center lines of a tubular chassis for a vehicle. With so many tubes, using the easiest method possible to intersect the tubes to allow for future adjustments is needed. I believe I have the fish mouth joints covered. What I am having trouble with, are the mitered ends. When I use the skeleton model for centerlines, the tubes obviously end where the skeleton ends. In the case of a 90 degree angle, the tubes do not connect on the outside (in my current method), without doing a length adjustment in a VSS, which creates it's own problems when later trying to trim to a surface, because there are now multiple surfaces created.

If in the future, I need to change the 90 to a 60 degree angle, I would like the ends of the tubes to regenerate from 45 deg to 30 deg.

To have the exturde endat 45 degrees, place an axis at the end point of the tube centerline and a datum plane through the axis and at an angle of 45 degrees. Select the extrude to selected point, curve, plane or surface option and select the datum plane.

My approach would be to position Datum planes in an Assembly at the Mitred joints and then extruding the tube to the datum planes. I do not have proe open now. But I suppose that would be my approach to the problem.

That does work Thank you.
