Those Inventor users familiar with virtual parts, will know that they are extremely useful for adding information to an assembly, that you may not otherwise model (for example grease or glue).
Virtual parts will appear in your model browser, and on your Bill of Materials. While these can be created manually, I thought that I would share a method of creating them on the fly, using iLogic.
I've adapted a bit of code from the Inventor API blog (link in the code below) to work in iLogic and to also run a couple of checks for us before creating the virtual part, the overall process is pretty simple.
The Code below starts by checking that you are in an assembly file. If the rule is run from a part file, you are given a warning, and the rule will exit.
If you are in an assembly, you are prompted for a name, this will be used for the virtual part.
If you specify a name that has already been used to create a virtual part, you are given an error message and the rule will exit.
If the name you specify has not been used before, the iLogic code will create you a new virtual part with that name.
The animated GIF above shows the code in action.
Enjoy!
