Subdivision modelling is a new area for Vectorworks. It was introduced it Vectorworks 2016 and it will allow Vectorworks to create extremely complex smooth curving shapes.
Subdivision services have been around for some time as a computer technology, but not implemented in computer programs very often. The subdivision surfacing techniques employed by Vectorworks have been developed by Pixar Inc. and Vectorworks are using their system.
“subdivision surfaces are polygon mesh surfaces generated from a base mesh object through an iterative process that smooths the mesh while increasing its density” www.holmes3d.net/graphics/subdivision/
Because this is a new technology for many Vectorworks users it it may seem unusual in the way that you edit a subdivision surface. in the chapter on basic concepts I will explain this new technology and how you can edit objects.
