SmartDraw

SmartDraw is a very complete plication for all types of diagrams that you need, has great virtues with respect to Visio that can be considered the number one in the market or at least used, when you need to diagram a project from the basic algorithm to the more complex gantt diagrams , this tool is very useful, it makes you much easier in work (in my experience much easier to use than Visio) the connection between diagrams is simpler, since finishing a diagram makes it much easier to do the following, has a wide range of options and templates that help you in the creation process, contributing to the development of diagrams for systems that you are going to develop, a very useful tool for projects where you need to correctly capture what you want to develop, use it, try it for yourself.

Its main against is the price, the full version is very expensive although it allows you to enjoy the desktop version and its cost is very high, I think you should download it to compete more in the market.
The speed of the online version sometimes fluctuates negatively, it is a mistake that must be corrected.

I has little to say for Pros: because it is just as easy to draw boxes without having this program. I learned every feature and applied all of the program's features. It is likely that you could get a beginning design to give to someone, as a simple floor plan, if that is what you need. But be sure to print it to preserve your work after each little change.

Customer service is practically nil and there is no "help" or troubleshooting. If you try to contact them for support, you have to wait and see if they will send you an email the next day - and they usually won't. If you get the email, it does not remotely address the trouble or offer to talk you through it if their "solution" or instruction is not on point. Really disappointing. There is no auto save unless you are working in the Cloud for this program. Further, it constantly just stops and closes itself - and dumps all of your work during that session, even if you have been saving! So, then the hours of work are permanently lost - no kidding, EVEN if you pushed save. If you use it, you must remember to save, save, save - after each little line or inclusion and then print. Then close the program before its instability causes it to just close itself as to the design you are working on. If you don't close it down, you will lose all of your work. Then - get this - when you reopen a file after it has decided to shut down, it says that there is a recovered work file and asks if you want to open it and recover it. If you say "yes" the program shuts down again, over and over and over. It is so unstable that it can't hold up to the tasks it claims to be performing with its features, such as layers, measurements, inserting photos, etc.
