Creating a User Coordinate System using Inventor API

[Anonymous]

I am working on an Inventor API. I am  a rookie in this field. I want to create a UCS in the active assembly document with the help of my API. I am using C# as programming language. And I am building this API for Inventor 2010. Please suggest a method to do that knowing the transformation matrix.

The UCS creation API was exposed since Inventor 2011.

I would still be interested in an answer to this question. I would like to use VBA to create multiple UCS's within a part file via an excel table. Any help for getting started?

I'm fairly sure I can get the data in from excel, but have landed on this post a few times trying to find what methods to call for creating a UCS inside Inventor 2012.

Thanks for the help!

Thanks! That's exactly what I was looking for. I didn't know to search for the UserCoordinateSystems Object.
