Hi Team,

Have been offline for the last few months, some great updates!

However I have noticed a shadow / artefact appearing on my designs after publishing changes to the WebViewer. It looks consistent across my drawings i.e. it does not change shape with different models. Image attached, any help to diagnose would be greatly appreciated!
