This method is to emulate the keyboard controls of InfraWorks and InfraWorks360 to use a joypad with InfraWorks.
I use a Xbox controller with USB.
To set this up I use a keyboard emulator called Xpadder
It is a freeware application which you can find on the internet.
Plug in your controller until it finds the device.
Next, add the sticks, dpad, buttons and triggers that you want to run.
Follow the steps to initialise each one
Next we have to tell it what each movement or button push will do in InfraWorks
Below is the setup I use
Save your profile.
Then to use it, just have Xpadder running in the background and your joypad all works :)
There is extended documentation on all the keyboard shortcuts on the help system
So much more fun than a mouse and low cost addition to your experience.
