Hi Mad Hatter, welcome to MoI!

Could you please post the 3DM file with your shapes in it as an attachment so I could examine your actual model?

It's very difficult to figure out what could be going wrong with only a typed-in text description rather than being able to examine the actual shapes.

There are some requirements that need to be fulfilled in order to get endcaps - stuff like the opening needs to be planar, and the rail curve needs to be closed.

Maybe your rail curve is not closed, if you could post it that would be one of the things that I would check.

Yeah that's the kind of thing that will happen if you are working with open surfaces rather than closed solids.

It tends to be easier to work with solids instead because then when you do booleans on the solid the results will be solid pieces as well.

Well, I'll be working soon on an updated one for v2 but there is a user manual for v1 already - just push the Help button to see it, or also it is available online here:
http://moi3d.com/1.0/docs/moi_help.htm

The PDF is the same user manual (minus the video tutorials) but arranged into one single document if you want to print it out.
