To Create Free Axes
Use the 3D Select axis tool to create a free axis, or multiple free axes. Each free axis you create is tangent to a 3D element contour at a single point.
1. Click the 3D Select axis button on the 3D Tools toolbar.
2. When the cursor becomes a , click a contour on an element in the drawing. A red free axis appears tangent to the contour at the point on the contour where you clicked.
3. To create another free axis, click another point on an element contour. A new free axis appears. The new (red) free axis is selected; the other (blue) free axes are not.
The figure below shows free axes created along the outer contour of a part. The selected free axis is red; the other free axes are blue.
