Midterm Overview - Box Plots

Sketch Plane Orientation

Assembly Constraints

Mate

Two surfaces associated with difference objects are set coplanar with directional vectors in opposing directions

Align (Flush)

Two surfaces associated with different objects are set coplanar with directional vectors in the same direction

Assembly Constraints

Offset

Same as Mate/Align except the planes are not coplanar but parallel, with an offset distance between them

Assembly Constraints

Align Axis

Axes of two parts are constrained to be colinear

Assembly Constraints

Tangency

Two surfaces are constrained to be tangent to each other either at a single point or along a line.

Assembly Constraints

Angluar

Two planes are angled relative to each other.

Projections

Rotated about one or two axes relative to the picture plane.

Axonometric
