I emailed you. Clara.io looks wicked! Also, it looks like it was a lot of hard work to write. Parasolid, Acis and ShapeManager have a lot in common because they all originate from the same Romulus family tree in Cambridge, United Kingdom. Parasolid is probably the most widely used in serious high-end CAD because it is used in SolidWorks, NX and SolidEdge. Replaying history based feature models is a very hostile evolutionary environment for a b-rep modeling kernel, so Parasolid is battle hardened in a way that would be hard for Open CASCADE say to match. If you are moving into CAD, then OnShape (VC funded cloud based MCAD by the founders of SolidWorks) might by a competitor. Do you know what they will use for their in the browser kernel? Unless they are roundtripping everything to Parasolid/Acis in the cloud like Lagoa (http://www.worldcadaccess.com/blog/2014/04/logoa-going-from-simple-rendering-to-cloud-based-cad.html http://www.worldcadaccess.com/blog/2014/04/logoa-going-from-...) that is. At the minimum, an in-the-browser sketcher would be good for cloud MCAD. I have thoughts, but not enough energy, strength and time right now to write one of those ... Edit: grammar
