I'm loading a file with 1 plan view and 15 cross sections. When I try to load the file now, the error message "CopySetToClipBrd Exception of type 'System.OutOfMemoryException' was thrown" popus up after drawing four or five of the cross sections. Eventually, the file will load, but the cross-section key maps are not drawn and I can't save out to a file.
Everything that you plot in the plan view where the x-sections were defined will be copied into the x-section key-map via the clipboard. You had so many objects visible in the the plan map view such that when the key-maps were being generated it was running into a problem with the clipboard. I edited the xml file by hand to turn off the visibility of the shapefiles and a number of the contoured objects. That allowed me to load the file without the clipboard error.
It appears that you had also exceeded some limit in the length of the xml file. I’ll have to look into it some more to see why that was occurring. I loaded the original file and deleted half of the x-section views and saved that result. I then did the same for the second half of the x-section views.
