NetRadiant/Interface

NetRadiant's two main methods of viewing, creating, and editing objects are the 2D view and the camera view.

Grid
NetRadiant uses grids to simplify accurate positioning of objects; the grid size (the distance between grid/snap lines) can be adjusted with the Grid menu or with the to  keys. All objects will snap to the grid spacing; if an object is halfway between two grid lines, it will not snap to the grid lines. Instead, it will move one full grid unit at a time, always staying halfway between two grid lines.

The grid is used in both the 2D and the 3D view.

2D view
The 2D view is located in the left half of the window by default. It shows an orthographic view of the map from either the top, the front, or the side. All map objects are shown as wireframe in the 2D view.

To pan, right-click and drag; the cursor will disappear and you can drag as far as you want without the mouse exiting the window. (The texture view also allows panning with right-click and drag.)

To cycle through the top/front/side views (which are also known as the YZ, ZX, and ZY views because of the "slice" of the map they show), press -.

Camera view
The camera view is a 3D viewport; its controls are similar to first-person shooter games. Unlike the 2D view, all brushes are fully textured, although shaders are not used. The camera view can be controlled with either the mouse or keyboard shortcuts.

To lock the mouse cursor so that you can look around, right-click anywhere in the camera window. Right-click again to unlock the cursor. To move forwards and backwards, you can scroll up and down with your scroll wheel. Note that the mouse doesn't need to be locked to move forwards and backwards with the scroll wheel.

There are three axes along which the camera view can be manipulated; left-right, up-down, and forwards-back. To strafe (move left-right), press or ; to move up and down, press  or ; and to move back and forth, press  or.

Additionally, you can tilt the view with keyboard shortcuts. To look up or down, press or ; to look left or right, press  or.

By default, NetRadiant's movement step distance is rather large; to slow it down, open the preferences window and adjust the Movement slider in the Settings>Camera view.
