I have a bunch of parts that are very similar to each other, with only minor differences between the bunch (small change in height, an extra hole, things like that). I am making drawings for all of these parts, and found it easier to just make one drawing completely, duplicate that drawing file, and then open the copied file and change the referenced part to the next part I need to draw up.
I have a section view in my first drawing, but when I try to do the second file by copy pasting and opening up the duplicated file with the new part reference, the section line disappears. Note that the section view is still there and looks perfectly fine, just the section line (the line going through the original view with the 2 arrows to indicate direction) is missing. I can't seem to be able to find it anywhere on the sheet or off of it. Is there a way to show where it is, in case it is hidden or something like that? Not really sure what's happening.
