Baglet: I am assuming you need to split the pattern on a horizontal line, corresponding with the colored areas on the legs?
Easiest way to do it inside MD would be to
1) add points along the seam-lines at the place you want to split the pattern,
2) save the garment at that stage,
3) move the 2d patterns of the pants to another area of the 2d workspace for easy differentiation.
4) use File>Add garment to bring in a duplicate copy of the pants; (it’s 2d pattern pieces will be in the original spot), [both pants will be in position and overlapping in the 3d workspace—less simulation work needed!].
5) In the pattern window; on one set of pants, select and delete everything below the points you added, and on the other, select and delete everything above that set; (which removes the unneeded overlapping portions),
6) sew the top and bottoms together, (and any side seam that got messed up by the deletion…it happens sometimes, sometimes not).
Using the internal lines *would* force the polys to line up along that line, so they could be more easily spotted for manual selection in a 3dmesh editor program, if you are more familiar with that work-flow.

Been busy with work the last month or so, and next month will be even more stressful. Luckily I have a week off coming up to de-pressurize and do some creation! I’ll get back to those turbans ASAP!
Here’s what I was started on before things got crazy at work; draping the cloth:
