Create PDM Attributes

The PDM ATTS sample program reads an existing data file, finds the first product in it and adds some sample PDM attributes like a release date, owner, and an approval. This is an excellent starting point for programs that add non-geometric information to STEP files.

The program does the following:

• Reads a STEP file and finds the first product. The file is a simple piece part so it only has one. If you would like to extend it to work with assemblies, the WALK_ASSEMBLY sample shows how to find your way around a STEP assembly tree.

• Create data for a sample person ("Tom Jones"), an organization ("Robot Fish, Inc.") and todays date.
• Assign Tom Jones as the product owner

• Assign an approval for the product version, with today as the sign-off date, and approved by Tom Jones.

• Assign today as the release date for the product version.

This program adds the attributes and saves the result as a STEP Part 21 file called "output_file.stp". This is a text file, so you can look at it with a text editor or the STEP Part 21 file browser to see how the information is represented.
