I am in the process of assembling sinks and appliance shapes for a new catalog. However, these will be primarily Australian (European) models.
The simplest way is to find a Sketchup item that fits the requirement. If using a sink, you have to be a bit creative as the sketchup shape will not create a ‘hole’ in a benchtop as one fo the existing sinks would. It’s not difficult to manually create a hole but it’s another step.
