# Length and Angle Measurement

Lengths and angles can be measured anywhere on the model with the Length and Angles option in the View menu. This option is fully 3-dimensional, and only applies to the 3-dimensional wedge views (3D Wedge View, Multi Perspective, End Wedges). It does not work with the 2-dimensional views (Opening Section, Support Designer Views).

NOTE: The use of the Length and Angles measure tool may take a bit of practice. Experiment with the option to see how it works. You should always carefully examine the location of the measure tool endpoints in all 3-dimensional views (Perspective, Top, Front and Side), to make sure that you are measuring the correct length and angle. If you are measuring between known vertices, make sure that the endpoints are "snapped" to the desired vertices.

To use this option:

1. First, you must be viewing one of the 3-dimensional wedge views ( 3D Wedge View, Multi Perspective, End Wedges, Front / Perspective).
2. Select Length and Angles from the View menu.
3. The length and angle measurement tool will now be visible on all 3D views of your model:
• This consists of a black line with "handles" at either end, which allow you to drag the endpoints of the measure tool to any 3d point in the view.
• Each handle is a small cube, coloured red or blue, to identify the start and end points of the measure tool, respectively.
• By default, the measure tool will be placed at coordinate z = 0 along the tunnel axis (i.e., in the plane which contains the apex vertices of all wedges). Depending on your model, the measure tool may be somewhat difficult to see at first. If you cannot clearly see the endpoints of the measure tool, then rotate the perspective view until you can clearly see where the measure tool is, in 3-dimensional space.
4. To measure lengths and angles, click and drag the endpoints of the measure tool to any location in the 3D views. You can utilize any view (Perspective, Top, Front or Side) to manipulate the endpoints of the measure tool:
• Place the cursor over either end point (i.e., the blue or red cube at either end of the measure tool), and the cursor will change to a four-way arrow icon
• When you see this icon, click and drag the endpoint to a desired location. As you move the endpoint, the length, angle and coordinate data in the selected pane, will be interactively updated.

NOTE: The measure tool will automatically snap to any existing vertex of the model (e.g., wedge, opening section or bolt vertices), when the endpoint is placed over a vertex. When the endpoint is snapped to a vertex, the cube will become larger, and will change from a dotted to solid line mode. See below for more information.

• When you release the mouse, the length, angle and coordinate data will be updated in all panes within the view.
• Repeat these steps until both endpoints of the measure tool are at the desired locations.
5. Length and angle data are displayed as follows (for example, on the 3D Wedge View):
• The Length between the two endpoints will be displayed in all 4 panes (Perspective, Top, Front and Side views). This is the total length as measured in 3 dimensions.
• The Trend / Plunge of the measure tool, from start to end point, will be displayed in all views.
• The 3-dimensional coordinates of the endpoints (x, y , z coordinates of the Start and End points) will be displayed in all 4 panes. Note that the colour coding of the text (red or blue) corresponds to the colour of the cube at each end of the measure tool.
• In the orthogonal views, the components of the length in the viewing plane, will be listed (Top View = X, Z lengths, Front View = X, Y lengths, Side View = Z, Y lengths).
• In the orthogonal views, the Angle of the measure tool, as measured in the viewing plane, will also be listed. Note: the angle is measured from the "local" horizontal axis in each view (Top, Front, Side).
6. You can use the zoom and rotate options, as necessary, to help you view the measure tool, to make sure you are measuring the correct dimensions (i.e. the endpoints are correctly located).
7. When you are finished using the measure tool, right-click and select Done , or press ESCAPE, to exit the option (the measure tool will disappear from the screen).

## Snapping to Vertices

In most cases, you will probably wish to "snap" the endpoints of the measure tool, to known vertices of the model (for example: wedge vertices, opening section vertices or bolt vertices).

• By default, the Snapping mode is toggled ON for all entities, so that the endpoints of the measure tool will always snap to the nearest wedge, tunnel or bolt vertex.
• If necessary, you can toggle the snap mode off from the right click menu. While you are using the Length and Angles option, right click and you can toggle the snap mode on or off for the tunnel, wedge or bolt vertices, as necessary.

IMPORTANT NOTE: When an endpoint of the measure tool is snapped to a vertex, the cube representing the endpoint, will become larger, and will also change from dotted to solid line mode, to indicate that the endpoint is snapped to a vertex.
