Measure 3D directions
Use the Direction 3D CoPilot to measure directions. Follow the directions in the Prompt Bar.
You can measure the 3D direction of:
Two points
A cylinder, cone, or torus
An edge tangent
Global coordinate axes (X,Y,Z)
Local workplane axes (U,V,W)
Normal direction of a face
View in a viewport
To specify which element to measure, hover over the element you want to measure, or use the right-click menu. All measure 3D direction functions start with:
1. Click Analysis and then, in the Measure group, click the arrow next to Direction.
2. Click Direction 3D. The Measure Output dialog box opens with X, Y, and Z fields.
3. Click the element to be measured or right-click and choose an option from the context menu. The X, Y, Z fields in the Measure Output dialog box shows the measurement of each direction.
Example: To measure the direction of a cylinder, cone, or torus
1. Click Analysis and then, in the Measure group, click the arrow next to Direction.
2. Click Direction 3D. The Measure Output dialog box opens with X, Y, and Z fields.
3. Hover over the cylindrical, conical, or toroidal face. Graphical feedback shows the direction of the axis of symmetry. Press the Tab key to reverse the direction.
4. Click the face.
5. You can click further measure options, or click to complete the operation.
