Tangent Tool
The Tangent tool enables if a model is loaded, and it aligns two faces so they are tangent or aligns a face tangent with a line, point, or plane. Possible face types include planes, cylinders, spheres, and cones.
See the Assembly Constraints Reference Chart for descriptions of all assembly constraints.
Note: You can use the Tangent tool to move objects without assigning
assembly conditions. If the objects belong to different components, uncheck
Create conditions in the Assembly Options panel before
moving.
