Old Bolting Method

Dear Experts

I am trying to Create a Bolt spec and wanted to bolt details in Isometric extraction.
I created a Bolt Spec and given a Bolt spec reference to Pipe Spec, but still I can't see bolt details while extracting the ISO.

Here I followed the steps to create Bolt Details as below:
Just give me feed back where I went wrong

[COLOR=#0000ff]Step Wise:
1: NEW BLTA / NSB.BOLTS
2. NEW BLIS / NSB.#300.STUD
3. NEW SBOL / NSB.SBDD
  Edit the Attributes as below mentioned
 
  Nstdblength Nulref -Nstdblength /M12
  Bitems unset - Bitems NUT WASH WASH NUT
  Btlength unset -Bitlength 20 2 2 20

4. NEW LTAB /NSB.LTAB
5. NEW DTAB /NSB.M12
  Attributes to be edited as below
  Btlength unset  - Blength (50 60 70 80 90 100)

6. Go to SBOL, and edit the attribute as below mentioned
  Nstdblength nulref - NSB.M12
 
 
7. Go to Category "Flange"
  create new BTSE
  Here Bthickness parameter should be updated as, Falnge thickness Param , which we defined during Flange cata
 
8. Under BTSE, create BLTP, name as NSB.1
  Attributes to be edited as below
  NUMBER 0  - Number 1
  Bdiameter - Bdiameter 12
  Btype unset - Btype BOLT
  Then stay at BLTP . 1
  Create N No. of BLTP as per Bolt No.
 
9. Then go to FLANGE (Scom), need to Set Blrfarray as same BTSE name

10. bolt spec to be generated.

11. Go to Pipe Spec, select one,
  Attributes to be edited as below:
  BLTMETHOD - NEW
  BSPEC - /NSB.#300.STUD.BOLT.SPEC (bolt spec name)[/COLOR]

First this is a NEW method but not OLD as in topic name.
Then not seeing your bolting spec it is hard to say what is wrong

post bolt spec please

Above steps were during training session I made. And this training held in 2006. and I was just using existing cats.
Just for a change I was trying to do my own, I could not.

Any experts Can help me

Hi Ruav,
Thanks Men, I got the solution, while spec creation, I given a wrong name for BLTREF.

If somebody is new for Bolting they can still follow the above steps.
