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/
Introduction to Subdivision Surfaces
Controlling Subdivision Surfaces
The basic concept of a subdivision surface is the cage. This cage controls the extent of your subdivision surface and it has all the controls to allow you to manipulate it. If your subdivision object is not selected it will not have the cage visible. As soon as you select the subdivision surface, you will see a bounding box. If you double-click on the subdivision surface, you will be able to see the cage.
