3D View Settings
Control how the mouse and keyboard interact with the 3D views — the Assembly View, 3D input, and 3D generated.
Open Settings → Client → 3D View and Control.
Navigation
For each of the three actions Move, Rotate, and Zoom, choose a mouse button and a modifier key. The action runs when you hold that mouse button with exactly that modifier key and drag the mouse.
| Action | Default |
|---|---|
| Move | Middle button (mouse wheel) + Ctrl |
| Rotate | Middle button (mouse wheel) with no modifier |
| Zoom | No button — you zoom with the mouse wheel |
The mouse button can be No button, Left button, Middle button (mouse wheel), or Right button; the modifier key can be None, Shift, Ctrl, or Alt.
The mouse wheel always zooms. Assigning a mouse button to Zoom only adds zooming by dragging.
A plain click without dragging still selects geometry; this binding cannot be changed.
General Settings
Invert zoom?
Enable Invert zoom? to reverse the direction in which the mouse wheel zooms. The option is off by default.
3D projection
Choose how the 3D scene is rendered:
| Projection | Best for |
|---|---|
| Perspective projection (default) | General viewing — objects appear with natural depth |
| Orthographic projection | Technical review — parallel lines stay parallel, no perspective distortion |
