Ive been a user of "Cubify Invent" which I believe is a condensded version of an Alibre Product that 3D systems packaged with their range of 3D printers. At the time, early 2015 I purchased it for $70. Unfortuantly they disconntinued Invent and Cubify Design (which allowed creation of assemblies, also compatible with alibre file types) so I missed out on upgrading to the software which could handle assemblies. Then I discovered Atom 3D which looked exactly the same as Cubify Invent, except Atom can do assemblies. However after using Atom Im finding more and more basic features which are missing. Features that a $70 program has but a $350 program doesn't.... Ive attached photos of the features I can't seem to locate on Atom 3D Can anybody tell me if they exist ? Photos are taken off of the 'Invent' program. Biggest point for me at the moment is being able to use only 1 type of arc. Are these things planned to be inculded in any upcoming updates ?
