Yes, very similar. However there is still room for improvement. Maybe Disney found a solution to make cleaner models, leading to a 3d-print ready solution. With 123D you need to spend time on cleaning the mesh.
Gahh! 9 out of 10 times, software made in academia has cool features but awful code/structure/packaging/younameit. In this case, the Linux (!) tarball contains Windows binaries and a handwritten Makefile that is not able to compile even the first source file. What a pity.
ps. this seems to be an open source version of 123D http://insight3d.sourceforge.net/ Interesting, but havent used it yet
