<@398467566588264449> 
ig. this usb-c has both SMD signal pins and THT mounting legs
so in circuitjsontogltf produces 3d png like this
'circuit-json-to-gltf` currently recalculates the model's lowest vertices when producing 3D PNG previews ?? right ??
checkout this https://tscircuit.com/seveibar/usb-c-flashlight its's 3d-png 
and here is what seve said : https://github.com/tscircuit/circuit-json-to-gltf/pull/189
Could you share how to clearly do the model origin vs. footprint origin for this hybrid SMD+THT component, or how to structure the TSX test for it?

Was this model imported by our easyeda converter

Maybe let's start by trying to repro there and see if there is an issue

I'm afk but I can hop in voice chat later today to troubleshoot
