BOLT LEN different on PIPE Level and BRANCH Level.

Material totalling and calculation is based on itemcodes.

Try flagging this:

Hi Corrado.

The bolting began to show when I UNSET a UDA that was created to show the PSPEC of components in the MTO, a client request.

But I now get multiple extraneous bolts.

I made a copy of my options file and turned on the Multiple Descriptions/Itemcode flag as you suggested but get an 'Options file error (47,15).'

How do I turn off the extraneous bolts?

I think you have some issue with your bolts catalogue/specification.

Why don't you open a Case (Tickect) with Aveva Support?

...

Will do...Thanks for the advice Corrado!

This was the reply for AVEVA tech support. Kudous to Omar Alani.

This specification contains only elements with the BTYP STUP. There are no elements with the BTYPEs WASH or NUT.

However, there are no WASH and NUT element in the bolt spec. So Isodraft can't find the correct information. Instead it is showing the detail and material text for the STUD. 

You need to add the definition for washers and nuts in you bolt catalog as well as all required catalogue components, detail text, and material text.
