About Projecting 3D Silhouette Edges

You can create the silhouette edges to be used in the layouts as geometry or the reference elements. However, there are a few things that you need to know before you begin creating silhouette edges.

About Use-Edges

When projecting 3D silhouette edges, remember the following points:

  • You can view all input geometries needed to create the silhouette edges in the specifications tree under the Use-edge inputs node.

    Using this, you can edit, delete, or replace the silhouette inputs, if required.

  • You can perform the following operations on the silhouette edge:
    • Update to reflect the design changes of its inputs.
    • Create geometry and apply the constraints.
  • If new 3D features are added after the last feature used for the creation of the silhouette use-edge, these new 3D features are not taken into account by update of the silhouette use-edge.
  • The Project 3D Silhouette Edges command generates one mark for each closed profile created in the resulting silhouette edges.
  • The created silhouettes are visible in the tree if the Use edges and the Use edge inputs check boxes are selected in Me > Preferences > App Preferences > 3D Modeling > Mechanical Systems > 2D Layout for 3D Design > Display section, in the Tree area.
  • The created silhouettes are displayed in yellow, by default. However, you can change their color from Me > Preferences > App Preferences > 3D Modeling > Mechanical Systems > 2D Layout for 3D Design > Geometry section, under Colors, the Protected elements list.
  • You can create a non-associative silhouette use-edge by selecting Isolate Use-Edge in the Tools Palette when silhouette command is activated.
  • If you apply the Parents/Children... command to a sketch containing a 3D silhouette, the Parents command shows the last solid feature that modified the silhouette.
