How to Export a Revit Model to SketchUp

February 26, 2019 In Revit SketchUp Tutorials


This tutorial will show you how to export a Revit file to SketchUp. There are ii methods for transferring a model. The first is by using a plugin, and the second is by exporting to a DWG file, and then importing into SketchUp. Both methods have their pros and cons. Using the plugin, the model retains it's original materials, but editability is sacrificed. Exporting to DWG retains maximum editability while no materials are preserved. Two case studies are used to demonstrate the capability of both methods, and a comparison of geometry complexity and file size are included at the end of this tutorial.

Software Required: Revit, SketchUp Pro, SimLab SKP Exporter (Revit Plugin), RVT2SKP (Revit Plugin)

Time Required: v Minutes
Difficulty: Easy

Tip:You must be in a 3D view to consign with either method. If there are model components (topo contours) or overlays (DWG files) that you don't desire in the SketchUp file, plough them off before exporting. The section box should be used to exclude any part of the edifice or topography that you lot don't desire.


Method 1 – Revit Plugin: SimLab SKP Exporter

SKP Exporter Plugin
Plugin Details: Single ($99) or floating license ($299) bachelor.

Later on installation, the plugin is available in the add-ins menu inside Revit.

Command
Detail level of the model is controlled by the setting in the 3D view (class, medium & fine). The model is e'er exported with textures, and can be inverse to shaded, hidden line or wireframe using the view styles in SketchUp. Additional alterations fabricated to textures, such every bit transparency, stain or tint are not carried over, as these features are not built-in to SketchUp. Model location is likewise non transferred in the export. The SketchUp file is saved as version 8, to retain maximum compatibility.

Method 1 – Revit Plugin: SKP2RVT Plugin

Plugin Details: Unmarried ($99 / twelvemonth) available.

After installation, the plugin is available in the add-ins menu inside Revit.

Control
Visual style, detail level and SketchUp file version is controlled by the exporter settings menu. Model appearance and geometry is identical to the previously mentioned plugin, while location and sun settings are preserved.


Method ii – Consign to DWG

Details: Uses Revit's built-in DWG export feature.

Step 1

From the file card, go to export > options > exports setups dwg/dxf.

revit export menu

Click on the solids tab, and select ACIS solids.

Pace iii

Hit OK, and return to the export menu > CAD formats > DWG. Make sure you are in the 3D orthographic view when you lot export the model.

Step iv

Import the model into SketchUp Pro. Here is what the Revit 2019 case house looks similar afterward the import.

Tip: In near cases, all geometry should reside on layer 0 (read SketchUp Layers: Part One – The Sacred Layer0 to discover out why). Use the Geometry to Layer0 command in the CleanUp3 plugin for SketchUp to automate this job.



Plugin Vs. DWG Comparison

Equally mentioned above, there is a merchandise off between materials and editability when deciding on which method to apply. The geometry exported using the two plugins to a higher place is triangulated, and faces that share a common edge in Revit issue in ii edges that are very shut together in SketchUp. A box that normally has 6 faces and 12 edges will have 12 faces and 30 edges. This causes a big increase in the number of edges and faces, and geometry cannot exist pushed and pulled, as neighboring faces are not joined. A downside to the DWG export is that subregions in topography are not separated from each other, which makes applying materials time consuming. If the topo surface is left white, all of the lines that form the surface, including the subregions, are hidden, which means that any roads, sidewalks or other areas volition not be visible in SketchUp. To create an platonic model with readable topography and editable buildings, consign any toposurfaces out using the plugins in a higher place, while using the DWG export method for any buildings that should remain editable. Statistics for two case study files are presented below.

Model Statistics for the Revit 2019 Example House

Consign Method Detail Level Edges % Change Faces % Change File Size (MB) % Change Layers Materials
DWG Export Form 301,669 150,948 17.1 31 1
DWG Export Fine 328,297 ix% 162,825 8% 18.1 6% 30 ane
Plugin Consign Class 441,948 47% 216,857 44% 37.ii 118% 1 63
Plugin Consign Fine 520,267 73% 242,700 61% 33.3 33% one 65

The image to the left shows edges and faces of the exported DWG file in SketchUp, while the right image is the file generated from the plugins.
