When you say you want to construct the hole, do you mean you want to model the threads? You can create a 3" NPT thread using the hole wizard and add a drilled hole on top of it. This will only have cosmetic threads but that should be sufficient for making manufacturing drawings. If you are planning on 3D printing or something then you would need to actually model the threads. If that is the case please clarify and we can give more details.
okay, thanks for your help.
I appreciate it!
