"Easy to use" and "software for idiots" are both very odd items to apply to graphics software, especially anything that has to work in a business environment like a vinyl
sign shop.
My experience has been the more
professional level tools have actually been easier to use than applications that were geared to attempt to be easy.
One example: Adobe Photoshop. On the surface, this seems like a pretty scary program. But if the user reads a little about how channels, layers and paths work and do so within the metaphor of Photoshop's interface the application seems very straight-forward. I've tried to use more
consumer oriented image editing applications and just wind up hitting one brick wall after another and after another again. The disappearance of certain critical tools and time-wasting wizards getting in the way of a simple operation make many such cheap applications counter-productive.
Flexi is not a difficult program to use. It is as straight foward as any vector-drawing program and has lots of CAD type program features as well. It's very simple to go through the users manual to find out how the tools work to set up items like banner layouts to cut from vinyl.
ChiefBL, this isn't a knock against your workforce, but some creative folks who have worked under me and claimed "the software is too difficult" simply did not want to make the effort to read a little and experiment a little to actually
learn how to use the software. Some expected to just sit down in front of the machine and magically have everything working.
Also, the website BadDesignKills.com had a funny illustration that pointed out another very glaring truth. In all graphics programs,
the creative concepts are not included.
