If you’re unfamiliar with 3D-model, navigation can take a little time to get the hang of.
• Left click to rotate the model freely.
• Right-click moves the model freely.
• Holding the middle mouse button and moving the mouse will zoom in and out.
• Scrolling zooms the model in and out.
First-person view lets you “walk around” inside the model.
Use W A S D for movement.
W = Forward
A = Strafe Left
S = Backward
D = Strafe Right
Clicking anywhere in the model will turn the camera towards where you clicked or keep pressing.
