That's true. And it's because most of it is based on common sense. Like trimming for instance. You can select everything, then you just pick whatever you want to discard. Mirror, rotate, scale, they're all pretty straightforward. Amapi Pro has its strengts, but I can't seem to really get comfortable with its line tools. I can't even do simple line trimmings the way Moi does it. BTW, is there a stretch tool in Moi? ;-)
You can scale in just one direction by doing Transform / Scale / Scale 1d.
That will be a type of stretch along the direction you pick. Let me know if you meant something different.
Once you have joined together surfaces, they don't tend to be very stretchy or squishable because it tends to be easy for the shared edges between different surfaces to pull apart from one another if I allowed for any type of random squishing of those types of things.
