Onuma SketchUp Plug-in (beta)

Onuma now has a plug-in that allows you to take a BIMXML file from SketchUp and open it in Onuma or vice versa!

Installation of Plug-in

First, download the plug-in HERE.

After unzipping the file, open the Onuma-SketchUp-Readme.pdf for installation instructions.
Note: To open a .pdf file you may need this free program: Adobe Reader.

SketchUp to Onuma

Watch How to Here:

Or Read How To Below:

You can start in SketchUp and save out a BIMXML file to import into Onuma.

Once you have installed the Onuma SketchUp Plug-in you will see the Onuma Toolbar in SketchUp:


This contains, from left to right:

  • A link to the Onuma Log-in Page
  • Create a building from connected volumes
  • Set up for floor-to-floor height
  • Create a multistory building from a single volume
  • Create a site
  • Export Onuma BIMXML

These tools allow for separate methods of working with SketchUp to create a building for Onuma; but first let's go over geo-referencing in SketchUp and adding a site, which is optional:

  • Geo-reference your building location using the SketchUp Add Location tool, help on this tool can be found HERE.
  • Next draw a polygon for your site
  • Select the polygon
  • Click Create a Site on the Onuma Toolbar

The site and location will transfer into Onuma when you export! Now on to making buildings:

Method One: Add Floors to a Volume

This method is great for building that only have a difference in floor-to-floor height on the first floor and for fast massing studies.

  • Click Set Up Floor-to-Floor Height on the Onuma Toolbar


  • Add data and click Save
  • Create a building using polygons, lines, and push tool
  • When finished select the whole building
  • Now click Add Floors on the Onuma Toolbar


  • Next click Export Onuma BIMXML
  • Name your file and add .xml
  • Save to a location you will remember

Method Two: Creating a Building with Individual Volumes

This method is good to use on building with a lot of variation in floor-to-floor height, or a lot of detail in general.

  • Create a building using polygons, lines, and push tool, creating volumes for each floor
  • When finished select the whole building
  • Click Create a Building on the Onuma Toolbar
  • Now click Export Onuma BIMXML
  • Name your file and add .xml
  • Save to a location you will remember

Once finished with either method, use the link to log-in to Onuma and then:

  • Go to your Studio and select a project
  • Create a new scheme using Add New Scheme From SketchUp
  • Select your saved BIMXML file
  • Choose if you want to add vertically aligned generic core spaces (elevators, stairs, bathrooms, etc.)*


  • Click Proceed

* Note: Vertically aligned generic core spaces are spaces are based on Onuma Global Templates, they are for visualization purposes and should not be used as assumed building requirements. They have vertical alignment assigned to them which means if you move or rotate one space, all the spaces above that match that space will copy that move and rotation. Read more on Templates HERE and read more on Vertical Alignment HERE.

Onuma to SketchUp

Watch Here Or Read How To Below:

To design your project in SketchUp first export a BIMXML file:
  • Go to Export
  • Select a building for export
  • Choose format Onuma BIMXML for SketchUp
  • Select a Color Coding
  • Click Export
  • Save the file

Next Open SketchUp:

  • Select Import from the pull-down menu under File
  • Select Files of type Onuma BIMxml File ( * .xml)
  • Browse and open for your saved xml file
  • Click Open


  • Prior to importing large BIMs, the Outliner window in SketchUp needs to be closed. This will improve the import speed dramatically - SketchUp uses a lot of memory to build the project tree in the Outliner.
  • Large models can take some time to import while the import of smaller models is nearly instantaneous. Use the Options button to import floors selectively. (Note: this method can also be used to import very large models in multiple steps to avoid memory issues.)

Additional Features

  • The SketchUp window Outliner shows the tree structure of the building. Right-clicking on each space allows you to access its attributes.


  • SketchUp and the Onuma-Plug-in allows the export and import of sites with multiple buildings and a site that is geo-referenced, i.e. has a specific location on earth. You can place it directly in Google Earth with Tools > Google Earth > Place or export the model as KMZ file to open in Google Earth.

  • Easy labeling in SketchUp. Using the Outliner to navigate to what you want to label. Then select the text tool, click once to place the label and click again when you are done. The label will be automatically populated with the group name in the Outliner, or you can enter a new name.
