Your own 3D parametric modeler.
FreeCAD is an open-source parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters.

Working around the topo naming problem isn't that big of a deal, for the most part, once you get the hang of it - often it's just a matter of reattaching sketches to the correct face, for example, and using parametric tables helps a lot as well.
To put it another way - I wouldn't avoid FreeCAD/Ondsel just because of this. And if it really, really is an issue, try a 0.22 dev build of FreeCAD for the interim.
With a complex assembly with 20 fillets it can take a half hour to reassign them all. There is no alternative or workaround and you need fillets for structural integrity in many cases.
It is definitely a big deal. For bigger designs you simply can't wait until the design is fully, 100% tuned and done at the very end to add fillets and chams which is the general "suggested workaround."
I made a complete flight stick in freecad. It was really hell having to rebuild every cham and fillet the model 4-5 times after a small change needed from printing the prototype that changed 1 edge and freecad now decided that a good replacement for the edge 200 chamfer is edge 13 on the other side of the model.
