The second example shows a case more similar to yours, in which the pipes are drawn in an elevation view.As you can see in the video, the Endpoint Osnap detects the endpoints of the CAD link, but when you need to go up or down, the endpoint won't be available because those points are at another elevation, but if you change the elevation, now the endpoints will be available again. dwg file linked into a Revit model, used as a base to make pipes tracing over the CAD link. The first sample shows a generic group of 3d lines in different directions, an AutoCAD.
topics including orthographic, isometric and oblique projections. This brief video shows two different examples: Graphics + Autocad Engineering Graphics and Design A Textbook of Machine Drawing. If you are going to work with Revit MEP, you don't need to start in AutoCAD and then link to Revit. Works with inch, millimeter or feet drawing units. Is there any way that I can then use this to 'snap' pipe fittings to so that I don't have to specify individual points and % inclines of pipe slope?You can, but you don't need to. 2D piping symbols, isometric piping symbols and P&ID symbols in one complete package. Just to clarify I have attached the Iso that I drew in ACAD showing that I did draw it at the correct angles not just 'flat'.
