This is a great program for creating 2D schematics. What I've noticed is that this program is essentially MS Paint with the exception of not drawing in bitmap, and the ability to output to PDF.
With that said, this program can essentially draw lines, squares, circles and arcs. I don't understand how it needs over 300 MB of ram to operate. I've been using SketchUp before trying Cooper. SketchUp's shortcomings for my needs is drawing in 2D mode (can be done but not designed for that purpose), and no control over the line thickness.
I've created massive 3D buildings in SketchUp with intricate detail, and only then did my computer begin to slow down. With Cooper, I've spent over an hour trying to resize 20 sets of text objects.
Based on the end output that Cooper can generate, I see this program as a marginal advancement in comparison to MS Paint. Given that SketchUp is free and uses much less memory resources for much more complex designs, I honestly don't see a future for Cooper in its current state. I would consider using a free version of this software package if its memory requirements can be brought down to 100 MB or less.
A paid version of this program would need a significant increase in the number of features and tools if it is to remain strictly as a 2D program.
It seems that this program was built not from the ground up, but from AutoCAD down. Being able to partially open DWG files in Cooper gave me that impression.
I would sincerely ask that the Cooper designers make a serious comparison between the capabilities of Cooper and MS Paint to see what advances have really been made, while taking into consideration MS Paint's age.
Seemingly spiteful but honestly sincere,
Henry
