The 18th Release of ParaSolid
Some CAD vendors use their own home-grown solids modeling kernel, like think3 and Autodesk. Most use a kernel from Dassault Systemes (Spatial ACIS) or UGS (ParaSolid). It's good to see what's in the new release of a kernel, because then you know what to expect in a future release of the MCAD software you use.
New in ParaSolid v18:
- Finer user control in local editing.
- More ways to thicken, taper, and emboss.
- Enhanced blending and filleting in tightly-curved regions.
- Localized behavior for hidden line removal and sectioning.
- Improvements to data tracking, rollback efficiency, and partition management.
I have yet to use a modeler that makes use of the Parasolid kernel, besides Unigraphics, where the surface and solid tools feel truly integrated.
I don't believe, and have not for some time, that if a company wants to build a hybrid modeler that using Parasolid is the way to go.
What I would like to know more about is the CATIA CAA kernel.
Perhaps SpaceClaim will use it for their new product?

Autodesk's solid modeling kernel is home grown?
Not exactly. So far as I know, it's ACIS with a few changes. Hard to say how many changes, though. Unlike Spatial and UGS, Autodesk does not document the native file format for their kernel.
