New bolting 'unable to evaluate' error

Have you checked that the flange (and/or nozzle) SCOM giving you problem is pointing to a DTSE containing a DATA element with its dkey attribute set to BDIA?

I'm getting a bolt error I've not seen before and I was wondering if any of you guys could shed some light on what is happening and why.

Catalogue error for component FLANGE 1 of BRANCH /ACE1105-20-01/B1 , catalogue primitive BLTP /ND-16RF-8-20-1 -
unable to evaluate RPRO BDIA
BDIA = 0.0 for bolt number 8 of BTSET /ND-16RF-8-20

Isometric bolt extraction is working on ANSI flanges but failing on the metric ones

The project default is Imperial and the lines from the boltspec are as follows.

Now the BLTPs are identical between the nozzle and the flange and have attributes as follows

Attributes
Name /ND-16RF-8-20-8
Type BLTP
Lock false
Owner /ND-16RF-8-20
Description unset
Number 8
Bdiameter ( ATTRIB RPRO BDIA )
Btype BOLT
Bthkness ( ATTRIB RPRO FLTH )

I've tried hard coding in the BDIA but then I just get a mismatch in BDIA attributes error, which doesn't mean that much because due the project set up I can't edit the nozzles to have the same BTSE.


Any ideas guys??

Try to navigate to those SCOMs and on the command line type Q  BDIA OF BLTP 1 OF BLRF NUM 1 OF CATR
It should give you as expected the bolt diameter.
If not...that's the problem.......hopefully :-)
It could be that some  of your BTSE doesn't have BLTP elements underneath?

I've got a DTSE that references the BDIA on the flange and Nozzle as per the following expression

( BDIA OF BLTP 1 OF BLRF NUM 1 OF CATR  )

Data type NULL, default 0

The property area of the form is populated with a definition of NULL and a No. set to a parameter value not on the SCOM

Here is where it gets confusing for me

They were the same, but that's when I got the unable to evaluate ATTRIB RPRO BDIA error mentioned at the start of this post.

I tried updating the flange BLTP's with a figure rather than an expression and now the Flange returns

Bdiameter ( 20 mm )

and the Nozzle returns

Bdiameter ( ATTRIB RPRO BDIA )

Now I've got it working to an extent if I override the nozzle BDIA with a specific figure (which is pretty much as Aveva supplied in the Master Pipe Catalogue) but I have concerns that this may come back to haunt me as a number of projects foreign in the master db for nozzle specs.
