Construction elements are used to aid in the definition and proper constraint of the final symbol geometry. Because of the way the symbol axes are defined and mapped to the 3D part, construction elements for sketched features and edge features can be constrained using horizontal and vertical constraints. These lines remain parallel to the symbol U- and V-axes in whatever orientation the feature is placed.

However, in a corner feature, the orientation and geometry of the symbol can change depending on the relative orientations of the two input edges from the model. Therefore, the construction elements used to define and constrain the feature symbol geometry should be constrained using the more flexible parallel , perpendicular , and tangent constraints.

The creation of a corner feature is very similar to creating a bracket. For more information, see Sketch and Constrain Bracket Geometry.

The following steps and examples address the creation of sketched and edge features.

  1. Make the Constructions layer active.

  2. Define the necessary horizontal and vertical construction lines relative to the symbol origin.

  3. Define and constrain additional construction elements (lines, circles, and so forth) as needed.

  4. Dimension the construction elements to further constrain and aid in the definition of the geometry.

  5. Click a dimension in the graphics view and type the dimension to adjust.
