Method for creatin symbol in pdms though Autocad

Sorry....what so difficult?
If I have understood you want to create a new user defined Isodraft symbol....am I correct?
You have the GUI that allows you to create leave, arrive, tee and spindle points. Then straight lines.
How much complicated is the symbol you need create?
Could you please post a picture?

Ok. I will wait for your picture.....
Anyway....you can make a big symbol in Draft. You can draw your 8 with many straight lines.
Then when you will export it in a symbol file you can scale it and make it smaller.
In Isodraft it will look perfect! Believe me! :-)

Thanks. I understand. I confirm you that you have to draw the two arcs by using many little straight lines.
Try and let me know....

Have you created your turbulent flow controller as an INST or PCOM?
Then you have to choose an appropriate Base Skey.
EXFL if a Flange one.
Can you please clarify? And can you post some pictures please?
