Dear Mr Diehl, Mr Ay or anyone who could help me.

Today I wanted to create stress isometric drawings from my Caesar II Project with the build in isogen and everything looks great except for the length of the Tees. Isogen is creating Tee-Sizes that are way lower than in ASME B16.9.
Example:
Tee 6" X 6"NS
Leg length 14 mm - instead of 143 mm

Please can someone explain why this is happening and how I can resolve that issue.

Thank you very much.

Just for clarification:

Caesar II Model:


diameter of header pipe: 914 mm
tee length needs to be: 673 mm (ASME B16.9)

Isogen from Caesar II is building this stress-isometric:




first tee length: 200 mm
second tee length: 100 mm

Why is there this error - where is isogen getting the information for the tees from? How can I get rid of this error?
Please could anyone help me with this.
Thank you very much.

Just a guess - try calling out a tee type in CAESAR II. Your image shows, now, that you do not have a tee identified: "SIF/TEE Type =".

You can also edit the PCF.

Dear Mr Diehl,

thank you very much for answering.
I checked now if the problem is that I didn't place in a Type, but I did - then I thought ok maybe my installation is wrong so I installed everything new but the problem still exists.

Mr. Diehl for me it is quite strange that I chose a Type for the Tee and in Isogen there is no type selected.

Maybe you have an idea why this problem exists.

Thank you.

Well, it was just a guess.
I just ran a quick model where I have two branch connections; one is labeled as a welding tee and the other undefined in CAESAR II. My ISOGEN plot shows both as welding tees and neither one has specific tee dimensions as shown in your original picture.
If you open that PCF file you will see a line beginning with SKEY after the group of lines defining the tee (END-POINTs, CENTRE-POINT, BRANCH1-POINT). In ,y model, both tees were identified (SKEY) as TEBW. This is a butt weld tee. If that SKEY does not appear in your PCF file, add it.

Thank you so much Mr. Diehl.

Really appreciate that.
