I need either an app or web based program to get the entry of pipe connection in a round structure and generate drawing. Basically from the math perspective you may use the centre of structure (circle) as reference point and the pipe can be drawn based on the angle and size of pipe from entry data. the software may already existed in offline configuration but I want to make that online, I currently have spreadsheet that foes the same but I want to make it online program. Please let me know your thought. I am located in western Canada.
