Mouse Buttons

The mouse is one of the most used tools for using NE1. NE1 makes use of a 3-button mouse to select objects, change the view, and perform other common tasks. Here is a summary of what each mouse button does:

  • Left: Selects objects in the graphics area, toolbar buttons, menu items and nodes in the Model Tree.
  • Right: Display context-sensitive menus.
  • Middle: Zoom, pan and rotate the view.

If your mouse has a wheel, you can push down on it to rotate the view. Scrolling the wheel allows you to zoom in and out on the model. By positioning the mouse pointer on the area you want to zoom in on and scrolling the mouse wheel, you can zoom in on the area quickly.

Mouse Wheel Zooming

Mouse wheel operations for all modes are identical.

Users without a mouse wheel should use the Zoom Tool and Fit to Window (CTRL + F) to zoom in/out

Action

Mouse Wheel

Zoom In/Out

Shift + Mouse Wheel

Quick Zoom (double-speed)

Control + Mouse Wheel

Slow Zoom (half-speed)

See Keyboard Shorts for how to recreate these operations without using the Mouse Wheel

Middle Mouse Button (Viewing Controls)

Middle Mouse Button (MMB) operations for all modes are identical.

Mac users with a single mouse button can hold down the Option key to emulate the MMB.

Right Mouse Button (Context Menus)

Right Mouse Button operations for all modes are identical. It simply brings up the mode specific context menu. In Build Mode, different context menus are provided when the cursor is over an open bond, a bond between two atoms or when an atom is highlighted.

Mac users with a single mouse button can hold down the Control key to emulate the RMB.

Y - constrain translation/rotation around the Y axis.

Z - constrain translation/rotation around the Z axis.

A - constrain translation/rotation around the selected objects own axis.

Tools > Extrude

While in Extrude, selection of chunks or jigs from the 3D workspace is not supported. You can select chunks and jigs from the Model Tree, however.

Action

Description

LBM + Drag

Move

Moves a Repeat Unit, which is one of the extrude copies of the original chunk to be extruded. The cursor must point on any of the atom centers of the repeat units in order to move them.  This is useful for connecting repeat units together in a chain, resulting in an extruded chunk.

 

Movie Player Mode

Left mouse controls are not available in this mode. You can select chunks and jigs from the Model Tree, however.
