Add angular measurements

Add locators that show the angle between three points.

To measure the angle between three points or locators

1. Click the Angle icon, or choose Measure > Angle from the Locators palette menu.
2. Click a locator for the endpoint of the first arm, or:
   • Click in empty space to add a world space locator, or type 3D coordinates to place the locator exactly.
   • Click a curve to add a curve locator.
   • Click an isoparametric curve on a surface to add a surface locator.
   • Click a mesh to add a space locator attached to the mesh.
3. Click a locator for the vertex of the angle, or click to create a new locator as in step 2.
   • Click the to place the end point horizontal to the start point
   • Click the to place the end point vertical to the start point.
4. Click an existing locator for the end point of the second arm, or click to create a new locator as in step 2.
   • Click the to place the end point horizontal to the start point
   • Click the to place the end point vertical to the start point.
5. The new locator appears. Pick and drag the label to change the length of the measurement leaders (see below).
   NoteThe points of an angle locator are displayed as crosses only when the Angle tool or the Move locator tool is active.

To edit an angular locator

1. Choose Windows > Information > Information window to open the Information Window.
2. Click the Move locator icon, or choose Move locator from the Locator palette menu.
3. Click the locator you want to edit.
   • Drag the label to change the length of the measurement leaders.
   • Use the options in the Information Window to edit the object.

Tips and notes

• The measurements are updated when you move or modify the objects or locators that the measurements are attached to.
• You can extend an angle measurement beyond the locators. The measurement draws extension lines connecting itself to the original locators.

Options

True

The true measurement in 3D world space (such as seen in the Perspective window).

Projected

The measurement reports the distance/angle as it appears in the window in which the measurement was created.
