For 3D modeling, I've still not found a replacement for Fusion 360. It does appear that there are products like shapr3d that are interesting for some basic conceptualization, but, there aren't things like, say, a sheet of default variables you can use to restrict your design to. It seems like these tools are for some rough sketching, but, the intent is probably to move the concepts into a desktop CAD system. This makes me wonder how big the iPad software market really is in comparison. It seems "tethered" to other platforms.
