(Exporting 2D DXF files) We design in a 3D world, but many parts are manufactured from flat sheet. The flat pattern of a sheet metal part and flat plates used in weldments are examples. Laser and waterjet cutters of flat parts may want to use a DXF file instead of native geometry. Let’s look at several ways to create DXF files.
There’s yet another way to do this. One of our customers wanted to make a SolidWorks drawing as an intermediate step, but the title block, dimensions and annotations were exported to the DXF and interpreted by the laser cutter as actual geometry.
There’s a solution: Create a second sheet and edit Sheet Properties so no format is displayed. Set the sheet scale to 1:1. Return to Sheet 1, select the Flat Pattern view and Control-C to copy it. There may be a warning that not all items in the view can be copied, but ignore it. Change to Sheet 2, left click anywhere on the sheet and Control-V to paste a copy of the flat pattern view. Now delete any dimensions and annotations. Right click the bend lines and Hide. There will be a message that bend notes will be hidden as well. Click Yes to continue. The desired result is Sheet2 that contains nothing but the outline geometry of the flat pattern, with no notes, annotations, title block etc.
Finally File > Save As > DXF, click the Options button and select “Export active sheet only” > OK > Save
The drawing now serves two purposes: Sheet1 is fully dimensioned and annotated as a design document, while Sheet2 is never printed but used only for DXF export.
