3D Viewer – A virtual reality viewer for 3D models exported from Chief Architect software. Visualize and navigate home projects before they are built using the Sojourn 3D virtual reality navigation tools. Walk or Fly through designs and experience exterior, room, cross section, and floor plan views. Use a virtual reality headset to immerse yourself in the model. Try it out, it’s fun!

To view models with 3D Viewer, export the original model with saved cameras from Chief Architect software to the cloud (provided by Chief Architect) and open the model using 3D Viewer. A great service if you are a professional builder/designer and want to share a virtual model with your clients.

Sojourn 3D virtual reality navigation:
-thumbsticks to move (fly) and rotate
-gyro camera for free form viewing
-background camera on / off
-walk thru allowing you to physically walk

Fast and easy to use. Very difficult if not impossible to isolate a single floor and allow easy overview of that floor. Have to align the slices perfectly and even then it leaves things all jittery. Great for overall viewing, horrible for fine detail viewing. And get that top bar off the screen its huge and gets in the way.

Good App Needs Improvements

Let me start off by saying that I love chief architect. I was super excited to learn about this app. It does a very good job of allowing you to view your design in 3D mode. It's very impressive in front of clients.......but it's way behind on going between a 3D view and a 2 dimensional floor plan. When sitting in front of a client you don't always need a 3D model. 2 dimensional plans are equally important when discussing layout and flow of an area.
An app that does this flawlessly is BIMX. It allows you to view your design in 3D or 2D plans. I'm not saying it needs to be exactly like BIMx but even the option of loading your 3D model along with a separate tab that also allows you to load your 2D construction documents would go a long way when talking to clients in a real world situation.
Keep up the great work. I can't wait to see where this app goes from this moment.

Could be very useful

Great idea. Got it to use with my field subs and clients.

Sent a link to share a model with them.
They could not load without creating an account with Chief it was hard for them from the shared model link and I had to help with that.

Difficult to share content. ID numbers way too long and links not as seamless as you would imagine.

3D texturing not very good. Would like to send models and be able to walk thru a plan in 2D and seeing in 3D.

Would be more useful called Chief Architect Viewer without the 3D and one could send 2D layers of 2D as well.

Thinking of it as a collaboration tool with end user recipients of shared content who are holding phones in the field would provide a better framework of how to
Redesign interface to make it truly useful.

I look forward to future versions.

Hello Dr Babaa,

Thank you for your review. Since your review we no longer require an account being created to view a model. The end-user no longer has to type in an ID number as you can just send them an email with the share link, they click on the link, and it automatically downloads and opens the model in the app.

Additionally the app has added features for viewing the 2D floorplan.

Here is information on how to optimize your model and materials for the 3D Viewer:
