OK, that makes sense, i.e., modify EABase as desired to get standard defaults (once one figures out what they should be) but also modify the individual project to suit. I gather that, for example, if I create a custom template in my current project and decide I want that to be standard, I then have to go to EABase and create it there too and then do something like copy my altered template over the top.
So, I have progressed to making a copy, but wanting initially to try editing it via Word, I used Save As, but it didn't ask me for a folder location and I can't find a copy anywhere ... off to experiment ... aha! So, Export, Edit, Import, and Save As under desired name and clean up. So, I now have successfully made some basic modifications to one template and used it. Thanks!
One thing I find odd is that when I view the generated documentation, the viewer is only about 1/4 the size of the diagram panel and it won't resize. Makes it not very useful. Is this a bug?
Now, the only other immediate issue, I think, is that when I print a diagram, e.g., domain model, the page border is very light on top and left and missing on bottom and right, even when I have convinced it that it is printing to letter paper. I suspect this is because it is right on the edge of or over the edge of the printable margin, but there didn't seem to be an option to adjust the margin in the printer dialog.
