Modify custom properties for iParts and iAssemblies members
Inventor users only
As stated by official Autodesk documentation (https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/Cannot-change-iProperties-and-parameters-in-iPart-members-using-code-starting-with-Inventor-2023-2.html), starting with Inventor 2023.2, iPart and iAssembly member files cannot be changed with code. Changing parameters and iProperties is no longer possible.
This is as designed. iParts and iAssemblies should be changed only by modifying the table in the factory file.
The possibility to change iPart and iAssembly members with code was disabled intentionally.
At today the limitaion is experienced with open files only.
Modification of the data through the RMB→Edit Revision/Data... is still effective.
