Hi William,
just some thoughts about the subject:
- There's no perfect solution, being all together the fastest, the most accurate and the better to handle.
- Junichi's isometric shapes are the fastest way to draw isometrics
- If you don't need pipe lengths and accurate numbers of bends, then you may look at the P&ID solution from Visio (professional).
- Biggest time savings will be realised be setting up a database based configurator for components. Chosing the components is much more time consuming than the drawing itself.
- You could model your pipework in 3D and create from these models isometrics and bill of materials, but that is very expensive and quite slow.
And last but not least, draw your own shapes, that's faster.
Cheers, Yacine.
