In my SketchUp extension I create a layer/tag which should be hidden or set to invisible by default. This has and still works in earlier SketchUp versions (for example in SketchUp 2017), but not in SketchUp 2020.
In SketchUp 2020 the layer/tag is set to visible after the extension created it.
box_layer.page_behavior=(LAYER_HIDDEN_BY_DEFAULT | LAYER_IS_HIDDEN_ON_NEW_PAGES)
I looked in the API doc; there are no changes on this.
Is this a bug?
