Thanks again for your help, Mitch.
I am on build 1317, not 1340. I have tried to download a more recent build but can't see how to do it (I have downloaded TurboCAD Pro 10 again but just seem to get build 1317). I am on Sierra v10.12.4.
I followed your advice and tried to export layer by layer, using a download of the same file you had worked on. The bottom worked OK but not the top, so I tried the top in two halves, left and right - and that worked!
I had to alter a hole size and so modified and re-filled the drawing and attempted to export it in the same way. The bottom was fine but not the top. I then tried doing the top in segments - left half and right half or lower half and upper half. None of these worked. I thought I would let you have a look at the top layer to see if you can do this as easily as the previous file or see what my problem is.
