Creating Iso-Thickness Junction Lines Manually

You can create junction lines from iso-thickness areas. They provide a greater stability when updating the solid after having modified the design .Iso-thickness junction lines are Generative Shape Design lines, that can be edited as such, based on the ramp support curves.

  1. Make a Geometrical Set the In Work Object.
  2. From the Solids and Top Surfaces from Plies section of the action bar, double-click Iso-thickness Junction Lines (repeat mode to create several lines).
  3. Select a vertex of a ply contour or an iso-thickness area (start point of the junction line).

    Note: Your first pick must be a Composites vertex (from a ply contour or an iso-thickness area): this provides a reference surface to create the junction line. After this first pick, you can pick Generative Shape Design points.

  4. Pick a second vertex.
    • For selected each vertex, Iso-thickness Junction Lines identifies the underlying ramp support, or reference element curves, and creates a Generative Shape Design intersection point between the two curves.
    • The Generative Shape Design lines created aggregate those intersection points.
      Note: When Iso-thickness Junction Lines identifies a boundary as a curve to be processed, this boundary is split by the underlying ramp support. The result is a Split, not a Line.
    • The line is created in the In Work Object.
  5. Repeat as required to create all required junctions lines.


  6. To update invalid junction lines after the solid creation, start a standard update after a modification.
    If a junction line is no longer valid, a message is displayed.
  7. In the message box, click Edit.
  8. Click Apply in the Solid from Iso-Thickness areas dialog box.
  9. Display the junctions lines list, right-click it to correct the invalid ones.
