The Edit View dialog will now appear.
Click on the DWG OPTIONS tab to access the Export Options as shown below.
You have 2 options to choose from:
Export Layers and Entities only used in this View - Select this option if you only want the layers that are visible in this View to be exported to a DWG/DXF e.g. If the Keep Clear Areas layer is not visible in this view, that layer and the entities on that layer are NOT exported to the DWG/DXF.
Export all Layers and Entities - Select this option if you want ALL layers and Entities exported to a DWG/DXF regardless of Layer visibility set for this View. This means that the recipient of the DWG/DXF file will be able to access everything on your floorplan.
