Sketchup to Revit

So I got asked the question how do I take a sketchup model and turn it into a Revit file?

To back up the first question I would ask is really? Because you can model everything in Revit much more accurately, and very quickly as well as keep Revit your primary modeling software that you're using for the job. Secondly, Sketchup is generally used for pretty pictures, easy graphics and 3d manipulation so for the most part I model in Revit and then export to Sketchup to make my pretty pictures...However, I can show you how to send it to either program either way.

From Revit to Sketchup:
Open your 3D view















File menu

Export -> CAD Formats

Click on the Options...

Specify under Solids (3d Views Only):

Export as ACIS Solids















(The only advantage I've seen with Exporting Polymesh is when you are exporting/importing complex model geometries and mostly this is used in MAX, Maya or Rhino for vertices editing)

Name your file, and hit Save

Crack open Sketchup

Once you're in Sketchup

File->

Import ->

Then specify under Files of Type ACAD Files .dwg

Then hit Open.

Alright so the next thing you notice is that when you click on your model it highlights the whole shootin match so click on your model right click and hit explode.















Now you can start painting up your Revit model in Sketchup.















Running a little low on time so to export from Sketchup to Revit, you need to have Sketchup Pro I've found to make it work best but essentially you need to go to:

File ->

Export ->

3d Model... ->

Specify ACAD files .dwg

Then Import the geometry into Revit.

The cool thing about this import is that you can replace the model walls with Revit building components to save you some time.

I copied the following below from the Revit Tutorials.


To import SketchUp files:

In the Revit project, create a mass or in-place family. See Creating a Mass Family or Creating an In-Place Family.


Click File menu


Import/LinkCAD Formats.

In the Import/Link dialog, navigate to the folder that contains the SketchUp file.

For Files of Type, select the SKP file type.

Select the desired file, and click Open.

SketchUp (SKP) files can be imported directly into a Revit Architecture mass or in-place family. For more information, see Large-Scale Massing Studies in SketchUp.

TIP:Make sure you import the geometric data needed for the Revit Architecture capability that you plan to use. For more information, see Suitability of Imported Geometry.

For additional information on working with SketchUp files in Revit Architecture, see Integrating SketchUp and Revit.When importing SketchUp files, consider the following:

Two-sided surfaces: If a material or color is assigned to only one side of a surface in SketchUp, Revit Architecture applies the material or color to both sides of the surface by default. If there is material on both sides of the surface, Revit Architecture applies the Face 1 material to both sides. If faces are flipped and painted differently in SketchUp, they may not display the correct material in Revit Architecture.

SketchUp properties: The following SketchUp properties are currently not supported in Revit Architecture import:

Texture Image Maps, Transparency, “Smooth” Curved Surfaces, Text and Dimensions, Raster Images, and saved “Pages”.

Cut planes: Imports cannot be cut by a cut plane unless imported into a cuttable family category. See Cuttable and Non Cuttable Family Categories.

SketchUp and Massing: Not all SketchUp imports are appropriate to massing. See Suitability of Imported Geometry.

Scaling: Groups or components that have been scaled in their entirety with the SketchUp Scaling tool may be incorrectly scaled when imported to Revit Architecture. Exploded SketchUp models should import at the correct scale.

Very thanks from sketchup4architect team.

Brad! If you are using SU just for "pretty pictures" you have missed a great opportunity. I am about design process of which SU is an integral part. I recently designed a project starting from massing models through concepts. Much of the work was done live and in front of the client. Final images using SU Podium added a little realism. Exporting to REVIT was the next step. My advice is not to be limited by one app. And, work from general to specific. Oh, did I mention the Google earth interface? And Form-Z etc.

Michael - Thanks for your comment! While I'm not suggesting that Sketchup can ONLY be used for pretty pictures it is been my experience that it is most effective with speedy visualization, not detailed and information rich parameter models. And yes the fact that Sketchup interfaces so well with Google Earth is definitely a plus!

"Because you can model everything in Revit much more accurately" is an inaccurate statement. Both Sketchup and Revit are as accurate as you make the model. You would be hard pressed to create a model faster in Revit than an experienced Sketchuper.

hi did this, and it came up with an error "Some ACIS objects could not be imported. To import them, use AutoCAD to convert them into polymesh objects and reimport."
what should i do?
also revit>google sketchup
solidworks>google sketchup

same alex, if possible, my email is alex.rodenburg@formworks.com.au

Cost, simplicity, low learning curve.

I work for a large global manufacturing company. We have hundreds of draftsmen/designers/engineers. Our products are part of a PLM structure with SolidEdge as our design software. However, our products are used in commercial enterprises and it has become necessary to create Revit models for our customers' A/E teams to use in their BIM design process.
There simply is no easy way to get from SE to Revit so Revit models have to be created from scratch. The cost to outfit everyone necessary to the task with Revit is astronomical. It is far more cost effective to have the basic models created in Sketchup then imported by power users with Revit to transform them into BIM families. I've worked with most major CAD platforms over the course of 25 years in A/E and manufacturing companies. I actually started off my career drawing by hand. The one thing I can tell you is that I have yet to come across a one-size-fits-all solution for anything.

Sketchup just for pretty pictures?..cmon man...you're missing a lot from sketchup..ive been using SU for quite sometime now and using Revit for 6 months..and i can say..for modelling SU is the best..i wont give up sketchup but will be continuing to learn BIM..these 2 are powerful tools in their own ways..both have pros and cons..anyway great post!..
