Hi Blair and thanks for your reply. The suggestion you posted is exactly how I do it (my file bakup is named BAK instead of 2017). But it feels like my question gets misinterpreted.
I do NOT want i add a custom property to the piping runs assembly. I want to add a custom property to the subassembly run and routes created within the piping runs.iam. Could you please test and verify the below steps to see if we get different results.
1. Open piping runs.iam
2. Add custom iProperty named "TEST" and change bom Structure to Normal.
3. Save your changes.
4. Create a new standard assembly and save it.
5. Create a new Tube and Pipe assembly from the environments tab. Keep the default names.
6. Exit the tube and pipe run and the tube and pipe environment.
7. open iproperties for the Run01 assembly (NOT the Tube & Pipe Runs assembly)
8. Do you find the TEST custom iproperty inside the Run01 assembly? (Yes, the TEST property gets added to the Tube and Pipe runs but not the Run01)
If your property has been added to the Run01 then something is wrong with my setup or brain.
If not, how do i add a custom iproperty (and change defauld bom structure) to the Runs i create?
Thanks /J
