Inventor 2017: iLogic Quick BOM Export

By Clint Brown

Have you ever wanted to quickly export your Inventor Bill of Materials (BoM) using iLogic?

Look no further, I have adapted some code from the Inventor API samples to export an Inventor Assembly BoM, the code checks that you are in an Inventor Assembly file (.iam) and then exports a Structured BoM (All Levels) to the "C:\temp\"  location.

The location that the BoM is published to can be edited by simply editing the "oPath" below. I have added commentary on the code below, and included the code for exporting a "Parts Only" BoM as well (this is commented out).

    Hi! Thanks for this code! I tried to implement to Inventor 2017 but I get an error message. Can you tell me what I do wrong?

    Hi Martin

    There are 2 possible reasons. The code has not been copied and pasted perfectly (something is missing or has moved). Or you are not running it from an Assembly file. To help ensure that the code is easy to copy and paste into a Rule, I have attached the code in a text file to the article, this should make it a bit easier to use.

    Good luck

    Hi Clint

    Instead of editing the output path in oPATH, can i get a code to popup a window to select path.
