Corel comes with a preset list of Scales. There is one spot to create a custom scale. I use Corel to do permit drawings about 40% of the time, and 1" = 10', 1" = 20', 1" = 100', ... are VERY common permit site plan scales. Corel does not have them in the list of defaults. Is there a way to customize the drop down 'Typical Scales' list?
I don't know if that information is customizable.
As an alternative, I think it would be straightforward to write some very small VBA subroutines, each one to set the document to a particular scale. If I recall correctly, I've read on this forum about someone doing exactly that for their often-used scales.
Those subroutines could be assigned to buttons on a toolbar, added to a menu, etc.
that would be great if i knew anything about VBA
