Welcome to the Arkio Help Center. Arkio is a design collaboration tool for architects and other spatial designers. On these pages, you can learn more about the app's features and workflows.

## Getting started

With Arkio, you can present your 3D models, review your models and ideate across VR devices, PCs, Macs, phones, and tablets. Arkio supports importing 3D models from various design tools. The best way to get started with this is by following our [basics pages](https://help.arkio.is/en/dashboard/articles/te1ho0g50cukk6t9/4410027792657).

# Learn more

You can learn about Arkio in our in-app tutorials, sample model and these support pages with helpful articles for your use cases.

## **Present**

The meeting Host can invite up to 24 viewers to a [meeting](https://help.arkio.is/en/help/articles/360002027678-start-and-join-a-meeting), switch scenes, gather users, and use [presentation mode](https://help.arkio.is/en/help/articles/360007655598-gathering-and-presenting) to organize the meeting. Using XR headsets, you can let users experience your models at scale and overlay them on the real world using Mixed Reality with [colocation](https://help.arkio.is/en/help/articles/13477304942876-colocated-mixed-reality).

## **Review**

You can [import large models](https://help.arkio.is/en/help/articles/360002027858-importing-large-3d-models) into Arkio on any device, save views, add [voice-transcribed Notes](https://help.arkio.is/en/help/articles/7460499998109-notes-and-issues), and [AI renders](https://help.arkio.is/en/help/articles/21566805980700-ai-camera). Collaborate on 2D [Frames](https://help.arkio.is/en/help/articles/21566881977628-frames) using sketches, share your scenes, export your 3D geometry, and Notes as a URL.

## **Ideate**

Modeling in Arkio feels like working with scale models that snap and glue like [physical building blocks](https://help.arkio.is/en/help/articles/360002018697-volumetric-modeling). The best way to experience this is by interacting with your models using an [XR headset](https://help.arkio.is/en/help/articles/360002016057-xr-hardware). You can collaborate with multiple users in real-time. After ideas are validated on a 1:1 scale, you can export your work back as native CAD/BIM tools using our [Bi-directional plugins](https://help.arkio.is/en/help/articles/360003164777-revit-arkio).
