I have a drawing that has multiple sheets. Here is how I create the drawing. I build the first sheet and hide/show certain components and sketches until I get what I want. I then copy and paste the sheet to create a second sheet. On the second sheet I hide and show more sketches. Now I have two different views that I will end up using on a laser cutter to cut certain parts from the original assembly.

Here is the problem. Sometimes (it seems it is random) I will go to the sheet that I want and save it as a DXF file. Sometimes it saves the currently selected sheet and sometimes (even though sheet B is active) it saves another sheet that is not currently selected and active. I have found that when this happens the only reliable way to get the correct sheet saved as a DXF is to delete all the other sheets that I do not want and then save the one I want as a DXF file.

Any ideas on what is going on here? Bug or something I am doing?
