I edit the model from the toolbox. In the ModelBuilder tab, I select Export > Export to graphic which opens the Export Image dialog. I navigate to the folder I want to place the file in and choose one of the formats, either SVG or PDF.
If I choose the pdf option, the pdf document is created but when I open it, there is an error message stating "There was an error opening this document. This file cannot be opened because it has no pages."
If I choose the svg option, the tool closes and a file is not created. (Yesterday, the pdf error occurred and I tried the svg format and it worked fine. Then today, the pdf and the svg do not work.)
I have a similair problem. In my case, I'm able to create a pdf which works, but I experience the same problem when exporting to .svg; the export image dialog closes but no file is created.
Was a solution to this problem ever found. I am having the exact same problem exporting my model to SVG and PDF. I have to be able to export to SVG for project submittal purposes.
