Avoiding Stray Geometry
Delete all floating and stray geometry from the upload file.
To do this, turn on all Tags. After turning on all tags, toggle Hidden Geometry, then use Zoom Extents. This should show any geometry in your model. We recommend taking a quick tour and deleting all the extra faces and edges that may have gotten lost during the design process. Failing to do so could affect the bounding box for the content you upload to 3D Warehouse.
