import model from revit and modify

[Anonymous]

Hi,

I am new to Plant 3D, I know basic level of AutoCAD and CIVIL 3 D. My new job requires me to import a REVIT model into Plant 3D and make some modification to the Pump station model- In terms of adding new pipes  and extending the existing pipes. Could anyone suggest the best way to go aboout it?

Quite coincidentally, over the past few days I have had several enquiries from AutoCAD Plant 3D users about the best way to reference a Revit model into a Plant 3D project.

Unfortunately, AutoCAD Plant 3D does not support the direct import of .rvt files. So, to reference a Revit model into Plant 3D, it must first be exported to an AutoCAD .dwg file.

Now, the .dwg file export from Revit may be configured to export detail in 1 of 3 formats: polymesh, ACIS solids or AutoCAD Architectural objects. However, of the 3 formats, ACIS solids is the only format that produces fully detailed Orthographic drawings in Plant 3D; but it also produces the largest file size too. Polymesh is a smaller file size and ARCH objects produce the smallest file size but each of these show inconsistant detail in Orthographic drawings.

So, from a modelling perspective, ARCH objects are the most lightweight, but looking at the deliverables, ACIS solids enable you to produce fully detailed Orthos. Don't forget too, that the ACIS solid drawing must be inserted as an attachment if you want it detailed in the Ortho.

Also don't forget that AutoCAD will now overlay Navisworks files, so you could go from Revit to Navisworks, then to AutoCAD.

As for modifying the actual Revit model, its not gonna happen. It just won't do it. Either do it in Revit or not.
