For those of you who are haunted by those darn Viewport and Image frames when your LayOut files are exported to dwg know that we will be addressing these issues. However, in the meantime, I would like to provide a simple workaround.
For this workaround I will assume you will be using AutoCad but similar features are found in other cad programs.
1.Open the exported .dwg in AutoCad or related cad program.
2. Create a layer and call it something like ‘viewport’ then make layer a no print layer.
3. In the paperspace tab select all your viewport frames
4. From the Properties panel, change the layer of selected viewports to your created ‘viewport’ layer.
Now, because you have placed viewport frames on a no plot layer they will not show up when plotted. Furthermore, you can ‘Lock’ the layer so that you do not inadvertently move or erase it or ‘Freeze’ it if you do not want to see the frame any longer.
Type imageframe and set to ‘0’ or ‘no’ or ‘off’ or something like that when it comes to the visibility of imageframes. This will then turn off the frames to the images.
Hope this helps.
