3d plant vs revit?

Can someone give me a quick rundown on the difference? There may not be a quick way of doing it, but not sure where to start with working in 3d.  Any help will be greatly appreciated. Thanks

Very quick version: AP3D is the piping, Revit is the building.  Vastly different programs due to the differences in industry e.g. piping is very hard science/engineering oriented where pretty comes second (or later) to other considerations; buildings are prettier but there's a lot of fidgety details needed to handle that.

so if I am doing structural and mechanical on a project, would I use both programs?  Are they interactive to where I can make the bldg in revit and then move it to Plant to finish the piping? Still confused on how they might work together. Thanks

Its not unusual for different departments to be using different programs based on their own needs.  For example, we've had projects with piping in CADWorx, structural in ProSteel, grade from Civil3D, and vendor equipment models from CATIA.  This is where Navisworks comes in - it allows all sorts of 3D models to be loaded together in context for coordination.

 

The real problems come from trying to generate ortho drawings.  You can't reference Revit Structural models directly into other program (not currently AFAIK, but that may change in the future).  For generating ortho drawings you need to get the structural model exported to a useable format but then any last minute changes might be missed so proper coordination is essential.  Other programs such as ProSteel which work directly inside DWG can make use of object enablers which makes things a little easier but still requires some forethought.

I believe current thinking:

 

Create preliminary structure in plant3d, run preliminary piping in plant3d.

Export plant3d structure as sdnf file.

Import sdnf into revit (may need to map member sizes).

Send from revit to robot for nodal struc engineer review and mofification.

Bring modified skeleton back into revit (revit updates model with robot changes)

Link Revit structure file into ASD for adding end connections / special details etc.

replace plant3d structure with ASD file (either as basic stick or with full detail depending on project size/requirments)

Rework piping to suit actual structure adding supports and extra structural steel to support the supports, this extra structure can then be sent back the structural team for adding to the live model.

run ISO's, review, Issue for construction.

wow....that sounds a bit more difficult that developing a few plans/sections!  Is it really more efficient?

Tools such as Revit are optimized for their given audience - not so good at piping (try generating piping iso's) but extremely good at building design.  Your structural designers will probably cry if they have to use a piping design tool to do building design work (keep those tears handy - they help ward off evil account execs 😄 ).  The trade-off is in the additional coordination required.

Could you Please help me to figure out the one below?

I do have to model and detail a complete project which involves Steel Structures & RCC Building, Piping and Equipments.
I have tools like Advance Steel, Revit, Plant3D, Inventor and Navisworks.

Please let me know the start point in developing the models and integration between the tools to generate output as desired.

 

Thanks

Plant3D <-XREF-> Advance Steel

Advance Steel <-Import/Export-> Revit

Inventor -ADSK Export-> Plant3D

Plant3D -Insert-> Inventor

Revit -Export to DWG / Export to AS (Depending on what you're doing) -> Plant3D

Plant3D -Export DWG-> Revit

Plant3D Structure -Export-> Advance Steel

Everything -> Navisworks

 

Depends on what you're doing, it might be a <-two way-> street, or a -one way-> function

What we have done is the Structure was done in Revit, imported to a dwg file.

Then using the dwg file as an xref using a datum point we created our piping dwg's, pulling each type of pipe out (ie; steam/condensate, NG, Sanitary etcd;) then using an master file xref all them into one master Plant 3D file.

This creates a smaller file which also allows multiple users to access the main model at one time and making the files smaller and easier to manipulate.

If the structure changes the Revit must update there dwg file and this will update in your model.
