You guys do know that Autodesk is a company, right? Comparing Blender to "Autodesk" is like comparing Gimp to "Adobe" - doesn't make sense. Autodesk has many softwares for modelling. Blender could be compared to Autodesk 3ds Max. SolidWorks could be compared to AutoCAD. Autodesk also has advanced modelling software, like Mudbox (comparable to Z-Brush, and with results that could never be achieved with Blender or SolidWorks). Not to mention Softimage and Maya. Blender is, indeed, an outstanding software. But since he didn't specify which Autodesk software he is using, it's hard to say he is wrong about working with it. That brings it to another subject, though. The developer's brag about using "Autodesk 2013" is very concerning. Autodesk's 2013-2014 build is terrible, and not telling us which software is being used points to a very amateurish approach. So, sumghai, your "LEGO" analogy is very accurate, specially in this occasion. I'll try to help him, though. But I don't think we'll make much progress.
