Some CAD softwares allow users to spin models handsfree. Wildfire 2.0 lets you spin a model as long as you hold the middle button. Here is a way to make Wildfire2.0 spin the model non stop handsfree.

Step 1.
Open the model in Wild fire.

Step 2
Click on the Orient mode button or click View > Orientation> Orient Mode>ON.

With the Orient Mode turned on click View> Orientation > Orient type > Velocity


Step 3
Keeping your middle mouse button pressed, spin the model. Don’t release the button yet.

Step 4
Press ALT+F or E or V or I or O or T or A or W or H to access the menu bar at the top.
When the menu drops down, you can release the middle mouse button.

Step 5
Now click the first mouse button anywhere on the screen. The position of the click will decide the direction and velocity of the spin. Move the mouse around to djust speed and direction.

As long as the middle button is not clicked the model will keep spinning.
