ok thanks for your answer!
Hi Alina, I have uploaded products with 2D AutoCAD before, but at the moment we don't differentiate between different formats of 2D files. When you do a product search and then scroll down to Formats and click on the "2D" tick in the left-hand bar, this will put a filter on your search to show only products that have 2D files attached to them. Once you download the zip file you can see whether it is suitable for AutoCAD
