Hi Roy and Welcome to JustAnswer.com. My Name is XXXXX XXXXX I look forward to assisting you today with your question.
Unfortunately, SmartDraw is not available for Mac OS X. It is exclusively designed for Microsoft Windows OS
So you will need to install Windows on your Mac to run the SmartDraw software. To answer your question, Yes it is feasible to install Windows on your Macbook Air.
To setup Windows on your Mac, there are two ways. You can install Microsoft Windows with the help of Virtual Machine applications like Parallels or VMWare Fusion OR with Apple Bootcamp utility.BootCamp
Installing windows on Mac directly by partitioning the Hard Disk and the Microsoft Windows can only access by restarting Mac OS. See the picture below about how you can access Windows and Mac
By Parallels or VMWare
If you installed Windows on your Mac using the Parallels or VMware etc then you can load Windows just by opening the application and run Windows from it. With Parallels/VMWare you can run Windows and Mac OS at the same time. So you have your Microsoft Windows and SmartDraw on one side and Mac OS X on other side. See a sample picture below;
BootCamp is from Apple and its free. But Parallels and VMWare Fusion are third party applications and they are not free.

VMWare Fusion --> http://www.vmware.com/products/fusion/overview.html
Parallels --> http://www.parallels.com/products/desktop/
You have to buy Windows OS to install either via Parallels/VMWare or with Bootcamp. You can buy Windows OS from Microsoft, eBay.com, Amazon.com etc. I'd recommend to buy Windows 7 since SmartDraw is not designed to work on Windows 8 according to some articles.
If you want to setup via Virtual Machine application, then buy either Parallels or VMWare. In my opinion, Parallels is better than VMWare Fusion.
If you have any questions or would like any additional information about installing Windows, please don't hesitate to ask me.
