Hello everyone. I'm new to the forum and fairly new to inventor. I'm detailing steel parts for large tanks that is done in a structural steel shop. I've figured out there is a linking ability with the parts to the bill of materials(BOM). So far I have found that I can link some of the iproperties to the bill of materials and I just found out about the custom tab, which I think is going to be a big help. I have used the custom tab to link a few things.

I want to make this as automated as possible so I am doing little work manually with the BOM. One thing I am wondering is if there is syntax that can be written to calculate the length in the parts Iproperties, so if I were to change the part it would automatically change in the BOM in an assembly drawing. I'm not sure how I need to go about this or if its possible.

If you have questions on what I'm trying to explain please let me know. I'm having a hard time explaining. Any help is appreciated.

Thanks
