Thanks! Dave
Thoughts (probably all very familiar)
1) I'm having a hard time adjusting the dimension values to anything "real-world". It appears the values come directly from the pixel offset from the screen edge. One idea is to put a customizable scaling factor in the various dimension calculate() methods.
2) I saw an email train about construction lines being offset from a reference con line but I had a hard time figuring out how to make them the same precise distance. I ended up laying out a number of lines then hand-editting in the XML file to be an exact offset.
3) Add a call stack trace to exception handling code - see the DumpException call below.
In fact thoughts #1 and #2 could be two parts to a general scaling calculation design. For example: describe how many con lines to fill the screen and the "real world" distance between them. That becomes your scaling factor. If you zoom out, you will need to add more con lines; call the same function but the scaling factor is immutable (or at least should be hard to change.)
Bug: When I took some examples from the default prefs.py file into my local one, I got an type exception. Here's the patch I did to fix it.
