Autocad has had a third party pattern making add-on for a long time, since early 90's (I used it a bunch of times, but no longer have it) and autocad does 3d meshes too (that's what I use at work about 80% of the time)

Even without pattern making add on's, autocad has spline modeling and extrusions and booleans so it's not all that hard to make a clothing mesh.  It's not the most productive way of making clothing meshes, but it can be done.
