1001 Bit Tools Pro vs. Free Version

Can anyone tell me the differences between the Pro version & the Freeware version?
I have tried Googling for a comparison chart but with no luck.

No chart, but this:

With 1001bit Tools Standard version you could create parametric architectural elements (eg. staircases, windows, doors, roofs, louvres, floor joists…etc) within minutes. With 1001bit Pro you can build even more architectural elements, plus there’re a lot of useful editing tools.

You can also save commonly used parameters for easy selection in future.

Currently there are 40 different tools inside 1001bit Pro.
Find out more about 1001bit Pro by downloading the user guides.

Last post 2 years ago on forum, latest version came out in 2012…

I will download the user guide as suggested for further research.
Thanks for the response!
