Revit Collaboration


Recommended Posts

I think it depends on how you define collaborate and what your expectations are.  I routinely import Revit bldgs for reference in my site, but I am not fooling with the bldgs themselves.  I imagine workflows of interior designers or various engineering disciplines working in Vectorworks with a Revit architect would have particular challenge truly collaborating on a “live” model, but I could be wrong.

 

My workflow is to create a reference file to hold the Revit import and then reference that into my site model.  Subsequent updates to the architectural model is then easy to update.  My work heading to architects for collab generally stay within the dwg and pdf realm instead of IFC, etc workflows.

Hello @PatStanford

 

yes I have some recommendations and suggestions.

 

a good BEP helps.

 

But the main issue is the Revit user themselves.

 

if they know what they are doing with Revit and can give and receive IFC, it is fairly straightforward.

 

like model setup there are rules when it comes to IFC and these should be defined in the BEP.

The reading I did earlier indicates getting up to speed with IFC is a key must do.

I have a lot of work to do.

You need to establish very clear aims.

What are you sharing information for? What do you really need to share in order to coordinate the design? Are you simply contributing to the set of 2-D drawings? Or are you actively engaged in a 3-D coordination process? Arguably unless there is a need to share in 3-D you don’t need to build a model to coordinate the design. You do though need coordinated 2D data and this means coordinated with the model as well as coordinated with all other 2D information.

I think you need to consider @shorter’s advice before diving into IFC.  Define the design process and deliverables before learning and deploying tools.

 

I have many Revit clients who can architect well, but have no understanding of IFC.  They really don’t need to when they operate within the comfortable bubble Revit provides.

 

I investigated IFC to initiate some file exchanges.  In the end, the clients would not or could not produce usable outputs in that format, so we either import Revit directly or use a more traditional 2D dwg exchange.  But I’m a landscape architect, so that is sufficient for me.  As a consultant to architects, I can suggest formats that may be helpful for me, but I ultimately happily accept whatever is easiest for them… they are the client after all.

 

Sadly, for buildings with fairly simple architecture, I can usually mock them up from PDFs faster than Vectorworks can import them.  Something to consider as you balance the marketing promises of what Vectorworks “can” do and what is a profitable workflow.

A key thing to remember with IFC is that it has a specific purpose and does not behave like native software when imported into Revit, vectorworks or any other Bim software.

 

To start with it contains little or no 2D data.

 

this means unlike DWG you cannot import an IFC and produce a (traditional) drawing.

 

A lot of line work often goes into making the drawing legible and complete in Revit (and Vectorworks) - Grids etc - and therefore you need to also request to the DWG data from model space to be able to use this for coordination in addition to IFC.

 

A lot of 2D data that might ordinarily be part of a 3D object like a door swing can go missing or be reinterpreted in the recipient software.

 

to think that you are sharing IFC in order to a, produce a set of drawings or b, see the 2D content visible in native software is naive but it’s amazing how many times Revit and Vectorworks users complain that they are not able to produce a drawing with a sheet and annotation etc from an IFC.  I had one express astonishment that the ubiquitous ’splash screen’ in Revit was omitted from the IFC. I nearly choked on my lunch that day.

Next installment of the VW > Revit discussion...  I feel like Charles Dickens.

 

ALL MODELS MUST HAVE A COMMON ORIGIN!!!

 

and by this I mean that all models (and when I say ‘all models’ I mean models from vw, rvt, SKP, 3dm, etc) must be aligned to the same internal origin BEFORE you apply any user origins, project base points or any other applied coordinate system.

 

if your internal origins are not aligned and are not in the same place relative to the model YOU ARE NOT COORDINATED irrespective of the ‘shared coordinate system’.

 

In order to do this you must not use the recommended DWG import settings in Vectorworks.  You must manage the process, set you user origin manually, and create a template for the project.

Can you say that in English?

What means 'models' and what means origin in that context?

Do you know where the internal origin is in Vectorworks?

 

This chap...

It's the centre of the model, where X, Y and Z are 0.

 

Revit has one.  So does SketchUp.  And so does Rhino.

 

In order to fully coordinate your Vectorworks model with someone using Revit, first make sure your origin and their origin are in the same place relative to the model itself.

 

Model = 3D data either solids, NURBS or BIM.  Matters not.  Any 3D data = model.

Yes, I grok. Thank you very much, shorter.

Very helpful.
