Mesh view: Navigation

Moving

Moving around in a 3D view can be achieved by a variety of means:

• drag the 3D view with the SHIFT key held down. We call this direct manipulation of the view centre panning.
• use the scroll bars on the 3D view
• use the cursor keys ↑ ↓ ← →. Hold the CTRL key down for larger shifts.
• move up and down with the PGUP and PGDN keys
• edit the view centre in the view parameters form

Rotating

Rotating, similarly, can be done in a number of ways:

• drag the 3D view with the CTRL key held down.
• use the rotate buttons . Hold the SHIFT key down to reverse the direction of rotation.
• use the rotate up, rotate down, rotate left or rotate right view menu items or shortcut keys CTRL+ALT+ ↑ ↓ ← →
• use the plan, elevation, rotate 90 or rotate -90 view menu items or shortcut keys CTRL+P, CTRL+E, CTRL+Q and SHIFT+CTRL+Q
• edit the view azimuth and view elevation on the view parameters form

Zooming

You can zoom into and out of 3D views with the zoom button , the zoom menu items, the shortcut keys CTRL+I and SHIFT+CTRL+I, or the mouse wheel with the CTRL key held down.

You can also zoom by the following means:

• To zoom in, define a rectangle around the area of interest on-screen using the mouse, by dragging with the ALT key down. When you release the mouse button, the region selected will be expanded to fill the window.
• To zoom out, define a rectangle by dragging with both the SHIFT and ALT keys down. The region shown in the whole window will shrink to fit into the rectangle drawn.
• To zoom in and out by a fixed amount, keeping the same view centre, use ALT+click and ALT+SHIFT+click.
