In BikeCAD version 8.1 while we can still open BikeCAD models the usual way by selecting File >> Open design from BCAD file, we can now also just drag and drop our designs into the BikeCAD window. In the above demonstration, we have a Windows file browser open with a few BikeCAD models. This video demonstrates how those files can be dragged and dropped into BikeCAD Pro.
Similarly, while we can still import photos into BikeCAD by selecting File >> Import photo, we can alternatively just drag and drop an image file right into BikeCAD Pro.
