SmartDraw

Pros: Make it and print it on spot really easygoing within 10mins I had a hold on ever setting used on site also I was able to learn what was expected of me to complete my diagram

Cons: Have to be computer savvy which means older people will have a problem using site

Overall: The best drawing site I have ever used because everything is mapped out for you in sections so there is no way you don’t complete your project

Pros: None for me, it is just a simple flowchart program that I can get for free.
Sometimes generic programs like these want to market to niche industries but you'll just waste your time trying to make something and fails miserably.

Cons: As a builder this won't work, its like a cheap Visio for flowcharts.
Zero features for pool builders.

Overall: Not good, just a generic draw program used for flowcharts mainly.

You need to use a pool-industry design program like PS or PoolTemplates to be able to do professional pool designs.
