There seems to be a lot of piping designers out there that are great at using 3D modeling software but are missing Pipe design basics. I’m trying to come up with a list of 3D modeling do’s and don’t that is not really software specific that I can pass on to junior/intermediate designers.

Here are just a few items that frustrate me:

• Modeled lines with inconsistent specs and line numbers that do not match the P&ID
• Equipment not shown in the correct elevation. Lack of coordination between Civil an Piping
• Valve hand wheels rotated at oddball angles e.g. 4” 300# gate valve hand wheel rotated 56 degrees
• Valve actuators modeled incorrectly, causing clashes later on. (even though the cuts sheets are available)
• Placing equipment in oddball coordinates /reference dims. e.g. 5’-2 1/16″

Please share your frustrations and ideas.
