Hi everyone. Thanks in advance for your help, this forum has been one of the best I've seen anywhere in getting help.

I've been working on my spaceframe design. I first drew the frame as "line drawing" using a 3D sketch, and then used the "structural member" tool to create my tube members. The structural member tool nicely joins the tubes together into beautiful joints by notching/detailing the ends of each tube to fit each other. But if I create more tubes/structural members as separate features then it doesn't do this, the tubes just end with a straight cut.

You can see what I mean here, where the left image shows a notched tube. The tubes were created as one feature and Solidworks notched the ends. The right image shows a tube that I added later as a separate feature and now it's not details.

In the above drawings it's not a big issue, but other times the result is terrible, like here:

What's the easiest way of solving this? I only need to fix the terrible joints. I tried creating all my members of the spaceframe as a single feature, but that won't allow me to have tubes of differing profiles, so no good.
