I'm working with Ultiboard for almost 10 years now.
Together with Multisim, it's a very powerful program in my opinion.
Powerful but waaaaay to expensive.
There are also some really annoying bugs I'm having in the newest version 13.
Sometimes,the auto zooming on finding a part doesn't work (it just zooms somewhere) and the clearance is messed up sometimes (even though it's correct in the settings)
Not a big deal with small projects, but a different story with a four layer DSP design with a lot of things going on.
And this is really what I don't get about those expensive software programs.
Sometimes some really basic instructions are buggy as hell.
The point is, that I'm looking for an alternative for years, but haven't found any program that is as fast as Ultiboard.
Because the great thing I like about Ultiboard is the quick way you can add, place, copy components, without the stupid restrictions some other programs have.
(like it's not possible to copy a multi part component or something, which is really annoying if you have like a 6 way output buffer
)
Even changing the value is just double clicking the component and directly hit the numpad keys.
Very fast and very intuitive.
I still wonder how people can make a big schematics when you need to scroll trough a long list all the time to place a component or something.
(or even adding the value)
And why on earth choice some programs to use odd short-keys?
(even for normal copy-pasting)
Anyway, like I said, I'm still looking for a free or less expensive alternative.
Still don't like the popular ones, unfortunately
