Importing Rhino And Sketchup Models Into Revit As Native ContentLuc DeckingaDigital Practice Manager, Perkins+Will@ldeckinga

© 2016 Autodesk© 2016 Autodesk

This class will cover the interoperability workflows that enable teams touse the tools appropriate to each phase of design, each team member’sexpertise and skill sets, enabling their imagination to be the limit of theirdesigns rather than the required toolsets. We will cover 2 different methodsfor importing geometry into Revit software as native content to producedrawings. With the first method, attendees will learn how to use FormIt 360software to translate SketchUp models into native Revit content. In the second,attendees will be provided with, and instructed on how to apply a premade,easy-to-use Dynamo script that will enable importing Rhino software-generatedgeometry into Revit native content. The techniques in this class have beendeveloped and tested on a range of project scales, from large transit projects toresidential high-rises to small tenant improvement projects with overwhelmingsuccess and quantifiable increases in team productivity and efficiency. Thissession features Revit Architecture, Dynamo Studio, and FormIt 360.

Class summary

At the end of this class, you will be able to: Work much more quickly during early design stages Create early design drawings quickly using Revit Use the best tool for the job in early design stages Help your team not be limited by their tools of choice

Why Do We Need This?...

© 2016 Autodesk© 2016 Autodesk

Use the right tool for the right task…

© 2016 Autodesk© 2016 Autodesk

No tool should dictate the design…

Inspired by Brian Ringley’s AU talk

© 2016 Autodesk© 2016 Autodesk

Revit is great at documentation coordination and management.

Revit is not so great at quick and agile design iteration.

What Revit Is Great At / Not So Great At…

….we need BOTH.

© 2016 Autodesk© 2016 Autodesk

Native Revit geometry has more graphic controls,

especially when cutting the object.

Imported geometry is limited in the graphic controls

and stands out as a result.

Building

Breaking BIM Down…

InformationModeling

We do Building Modeling well, but most of the

time the Information part of the process is

neglected.

The barrier to interoperability in BIM is applying

the information to the model.

Running The Script…

© 2016 Autodesk© 2016 Autodesk

Try this out before you needed it. Give yourself some extra time the first time. Don’t wait until and hour before you need to submit to try this.

Troubleshoot the script with a Cuboid / Box in Dynamo.

Break your geometry up into simpler parts. Revit will like it better.

Add more control points if the surface is inaccurate.

Any time you start with an existing Revit model and want to import something, first export a portion of your Revit model to the software you are designing the geometry to be imported in.

Most of all, remember Revit likes solids…

Tips For Success…

© 2016 Autodesk© 2016 Autodesk

Check Your Geometry: Sketchup

© 2016 Autodesk© 2016 Autodesk

Check Your Geometry: Formit

© 2016 Autodesk© 2016 Autodesk

Check Your Geometry: Rhino

Pros Batch Import Naming control “Edit Family” after import Geometry appears completely native Works with legacy versions of Revit (2015-2017 confirmed)

Cons No system families

Dynamo Import vs Revit 2017.1 CAD Import

Pros No Dynamo needed Works with system families

Cons Cannot “Edit Family” after import No control of naming Obviously imported Does not appear in the Project Browser

© 2016 Autodesk© 2016 Autodesk

Complex forms tend to be lighter when imported, due to absence of construction geometry in family. 400 MB linked project file to a 10-20 MB family in the main project file.

Allows team members who do not know advanced modeling in Revit to contribute to some of the most complex parts of the model.

Allows rapid design iteration to be added to the drawing set before it is fully modeled.

Reduces remodeling required in early design phases to produce a drawing set.

Allows for fabrication level models to be imported back into Revit.

IMPORTED FROM RHINO

OPTIMIZED IN GRASSHOPPER, CREATED IN DYNAMO

CREATED IN DYNAMO

What used to take a team of 4, 3-5 days to do, can be done by 1 person in 1-3 hours. 20% of a 2.8 M SQ FT project imported by end of DD phase.

Project Examples…

© 2016 Autodesk© 2016 Autodesk

Small infrastructure project, 98% imported in 8-10 hours. No Revit model at 50% SD, full Revit model at 100% SD 2 weeks later.

Project Examples…

SD Revit model driven entirely by Grasshopper…

Project Examples…
