Both programs were developed to work on high end consumer laptops, which meant being able to work on IBM PC and therefore DOS.
Those programs also were likely 2D in their initial versions in the 1980’s. They were also competing against human drafting, which was considered to be industry standard at the time.
Cost and ease of use were likely more important than other potential users of 3D software, so they went with DOS and made the transition to Windows.
