That makes no sense though. What if I have a camera and geometry and all I want is to align them? The ModelBuilder has the workflow for that but wont allow it apparently. I reckon the workflow in the ModelBuilder should be usable for aligning existing geo to existing cameras and vise versa, aligning camera(s) to geo.

Of course it's a different story if you want to track a camera to existing geo

Aligning geo to the camera was moved into the cameraTracker when we updated it in v8.

    Ah, cool, I was wrong. I never use the geo pipe since I realised
    it won't let you align the incoming geo to the camera - or can it
    do that by now?

    The Modelbuilder has a "Geo" input pipe which will allow you to
    snap geo to vertices from any input.  You can use this with point
    clouds from the CameraTracker or the PointCloudGenerator.  This
    is also good for keeping the scale the same between two solves.

        You can create primitives in ModelBuilder but you can't snap
        them to other vertices afaik. You can't import geo and edit
        it in ModelBuilder either. Try EditGeo instead (but don't
        hold your breath).

        Hello All,

        I have a basic card that I made from selecting some solved 3D points from 
the CameraTracker node, right-clicking, and selecting Create -> Card.

        I would love to pull this geo into ModelBuilder and tweak it. Is there 
a way to import geometry into the model builder node? As an alternative, can 
you create primitives within model builder and snap them to existing geo, such 
as vertices or faces?

        Thanks!
