Rhino - Arkio

Importing models from and to Rhino requires a Pro or Enterprise license. You can learn more about our paid licenses on our website and can start a free trial from Arkio to try this feature.

The latest Revit, Rhino and Sketchup plugins are included with our Windows installer that can be downloaded for free from our website.

The Arkio Rhino plugin allows you to export and update models from Rhino 6 and 7 to Arkio. We currently support exporting NURB and Mesh models with materials, and textures to Arkio and exporting Arkio creations back to Rhino meshes and components following the original coordinates. 

Rhino to Arkio

To export your models from Rhino you need to have the Arkio plugin installed, choose a 3D view with the elements visible you want to export, and press the export button found under the additional toolbars.

Clicking Export to Arkio will ask if you the following Export settings in the console

You can use the default setting by just hitting enter twice. If you need fewer polygons for loading Rhino models on mobile devices like the Oculus Quest you can try exporting with lower values like 0.2 or 0.3 or use higher values if your round geometry needs more detail in Arkio.

Once you open Arkio on the same PC, your export can now be accessed from the create>import drawer.  You can place the models in your scene and share them with your other devices in a meeting.

You can also upload your exported models directly to your (mobile) devices by uploading the ZIP file (or OBJ, MTL and texture files) on your Windows from \Documents\Arkio\Import\Rhino to your Arkio Cloud group.

Use Locked at origin to load the model as a locked reference with the same coordinates (eg. to review and draw designs on).

Or use Place as object to place your model as a movable object (eg. a piece of furniture that you want to place in the scene multiple times)

Model Updates

When a change is made in Rhino you can overwrite your model with a new version using Arkio on Windows by just hitting export again. While a model is imported in Arkio it shows a spinning indicator on the file overview. When the new version of the model is available a yellow update icon will show above the model in the Arkio scene. Clicking this yellow icon with your VR laser or mouse will update that model with the new version. 

Arkio will keep the old versions of your imported models available so you can always revert back to an older version when needed for e.g. comparing design options. You can access all the older loaded  models in the import model dialog. If you select an older import date from the dropdown you can update the model placed in the scene by clicking "Update in scene"

Arkio to Rhino

To import your models from Arkio back to Rhino you can open the Scene overview and click the export button. Here you can prepare the models to various supported tools including Rhino. Once the export is made for Rhino an export confirmation will be shown on your models.

Back in Rhino you can open our ArkioRhinoPlugin toolbar import to go to the Arkio/Export/Rhino folder and select the file you want to import. All Arkios geometry, components, sketches and 3D map buildings will then be converted to Meshes in Rhino.

If you like to Arkio geometry into editable Rhino geometry you can also use our close intergration with Autodesk Revit to convert your Arkio scene to solid Revit families first and then export to a DWG. You can read more about this workflow here.

Known issues/limitations:

• A restart of Rhino might be required when you run the Arkio plugin for the first time 
• Arkio currently only supports one-sided faces please make sure your Rhino models have closed polysurfaces and your single-face surfaces are modeled with the normals facing outward to prevent missing faces or inverted-looking shapes.
• Loading of heavy files is not recommended, try to keep your models below 450K polygons to avoid crashes and VR performance loss when working with mobile devices like the Meta Quest.
• If you experience issues loading your models try to load the OBJ exports in the Windows 3D viewer, Blender or 3DSMax to see if the files load well there and what geometry might be causing the issue.
  
• Try to reduce surfaces with a high number of Isocurves as these will result in unnecessary high polygons. Rebuild surfaces with cut geometry or more than 5 U/V isocurves
• Sometimes failing imported models affect the loading of other files. Cleaning your temporary ResourceCache files can solve most issues.
