Is there any CAD gui vertex editing in MMA whatsoever?
ie. can mouse be used for vertex editing or mesh bending in 2D or 3D within MMA front-end? Is there any add-on that does simple editing (note: that is not a $2000 expensive addon i can't fund)?
System Modeler (i can't afford it) may - might - but I cannot tell from product writeup if it has a CAD interface included.
(There are big suites like sketchup, but it seems like MMA's Import/Export from these are barely supported (I might be wrong), and definitely don't export well (cannot a whole plot3d with mult. objects - maybe 1 Graphics3D obj can export at best). I'm unsure what need those are if one could do the more basic CAD editing in MMA front-end. Something like sketchup is big to install and use even if free - thus I'm avoiding.)
