ROTSTEP questions

[N. W. Perry]

REL seems to be relative against the base rotation, so it's not progressive.

ADD (according the mlcad docs) should be adding to the current xyz angles, but in LDCad I multiply the current rotation with a newly constructed rotation using the given angles.. This because I don't keep track of the angles outside the step meta.

That seems to make sense. I think this is the intended behavior of ADD, even if it has unintended consequences. It's supposed to add the given rotation to the current view—NOT necessarily the view given in the previous ROTSTEP. (Because you might rotate the view manually, and then you go to the next step…)
