Inserting an Axis

1. Click Axis in the Create group on the Design tab.
2. Select one of the following:

   Select:	To insert an axis:
   Axial face	That contains the face's axis
   Two, non-parallel planar faces	At the intersection of the theoretical planes containing the two faces
   Linear edge	That contains the edge
   Cylinder and tangent plane	At the intersection of the cylinder and plane
   Line	That contains the line
   Origin axis	Along the origin's axis
   Circle or arc	That contains the center point and is normal to the line
   Point and a plane	Through the point and normal (perpendicular) to the plane
   Two points	Through both points
   Three axes	At the point where a cylinder's axis would be positioned between the three axes

3. (Optional) Click the Build Line tool guide to select reference objects, then select a temporary (dotted) line to create the one that you want from the possible axes. See Inserting temporary points, axes, and planes for detailed information about creating temporary lines.
