Thinking about doing a LDCad 1.7 version

Looks like it was the same group vs. submodel problem. I can recreate the problem by selecting just the first helper part, and the group; it calculates the angle using the two parts in the group as getRef(2) and getRef(3), ignoring the second helper part.

Ah I forgot about groups in my little test scenario, you can fix that by using getLineCount() / getLine() instead of the ref variants.
