Do you want to write an API or use the existing API to automate SolidWorks? I assume that you want the latter. There are a couple of links, in the FAQ section of this forum, that have source code samples. There are also a bunch of threads on this site that include sample code. If you have any specific questions, just post them here. There are plenty of members that can help you out. DimensionalSolutions@Core.com
