Measure 3D axes
Use the Axis 3D CoPilot to measure axes. Follow the directions in the Prompt Bar.
You can measure the 3D axis of:
Two points
A cylinder, cone, or torus
An edge tangent
Global coordinate axes (X,Y,Z)
Local workplane axes (U,V,W)
Horizontal axis of a workplane
Vertical axis of a workplane
Normal direction of a face
To specify the axes to measure, hover over the element you want to measure, or use the right-click menu. All measure 3D axes functions start with:
1. Click Analysis and then, in the Measure group, click the arrow next to Direction.
2. Click Axis 3D. The Measure Output dialog box opens with 2 sets of X, Y, and Z fields.
3. Click the element to be measured or right-click the viewport and choose an option from the context menu. The X, Y, Z fields in the Measure Output dialog box show the measurement of each axis.
Example: To measure the axis of a cylinder, cone, or torus
1. Click Analysis and then, in the Measure group, click the arrow next to Direction.
2. Click Axis 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.
