According some aspects, a user may drag an image displayed in a web browser application displaying the tool supplier's web site to a CAD application. Program logic associated with the CAD application may process arguments in the drag and drop event to determine a first resource identifier associated with the image, such as an image URL. The event handler may replace an image file type extension with a CAD file type extension to generate a second resource identifier, such as by replacing the image file type extension with a file type extension associated with a CAD stencil file. The CAD application may attempt to use the second resource identifier to download a CAD file, such as a CAD stencil file, corresponding to the product depicted in the image. The CAD file may be used to generate a CAD drawing comprising a stencil and/or other schematic depiction of the product.
