SOLIDWORKS Property Tab Builder 2016

Property Tab Builder is a stand-alone utility you use to create a customized interface for entering properties into SOLIDWORKS files.
The tabs you create with Property Tab Builder appear in the SOLIDWORKS interface on the Custom Properties tab in the Task Pane. You create different tab templates for parts, assemblies, and drawings.
