Changing Camera View from Perspective to Orthographic Using API?

[knightsAHN63]

Hello all! Has anyone written any scripts or add-ins that change the camera view type? We are developing an add-in and hoping to automatically change our user's view to ensure that it is only 'Orthographic' instead of defaulting to perspective. Any advice is greatly appreciated! Attached is quick screenshot of what we are hoping to do with API.

Hi @knightsAHN63 .

You can switch between them using the Camera.cameraType property.

The camera is retrieved from the Viewport.camera property, but be aware that you need to reassign it to get a copy.

The zoom position is quite different from when the cameraType is switched in the GUI.
I've used it here. I couldn't figure out the formula.
