The Mesh Edge Highlights toggle, hide or show the mesh edges of both the 2D and 3D flattening meshes.
Strain Highlights toggle, allow the user to adjust strain rendering on the model. Turning the strain highlights on will shade the mesh according to strain.
For example, if 20% strain is set to red, the pattern mesh will be rendered in red where the 2D pattern piece must stretch 20% in order to fit onto the 3D pattern piece.
Flattener Cancel can be used to stop remeshing and optimization algorithms. A single piece or a range or pieces can be selected for cancellation.
Flattener 3D Window allows the user to visualize the 3D analysis mesh. Strain is rendered on the 3D mesh according to legend settings in the ExactFlat 3D options. Flattener visualization options can be adjusted here.
Flattener Zoom Dynamic command can be used to zoom in both the 3D and 2D views. If Zoom Dynamic is active, left clicking and dragging vertically in both windows will zoom the current view.
Alternatively, the model can be zoomed by holding Shift + middle mouse button down and dragging vertically in both views.
Flattener Pan command can be used to pan in both the 3D and 2D views. If Pan is active, left clicking and dragging in both windows will pan the current view.
Alternatively, the view can be panned by holding CTRL + middle mouse button and dragging in the windows.
Wrinkle highlights alert the user that the current 2D mesh pattern has triangles that are flipped. If these are visible, a stretch algorithm should be run on that piece in order to eliminate wrinkles.
Flattener 2D Window allows the user to visualize the 2D mesh patterns. Strain is rendered on the 2D mesh according to legend settings in the ExactFlat options.
ExactFlat will determine an algorithm to perform initial flattening based on the ExactFlat surface type.
Mesh Status indicates the quality of a flattening mesh. A good mesh will allow the optimizer to run quickly, and will be unlikely to produce wrinkles in the initial 2D result.
Characteristics of a good mesh:
- Uniform triangle size.
- 6 triangles share each vertex.
- Low aspect ratio triangles (each edge should have edges that are close to the same length).
- Low vertex count (Shape should be represented well without using too many triangles).
The pattern status indicated the amount of progress the optimization algorithm has made removing strain from the 2D pattern.
The Piece List in the flattener contains a list of all the non-planar pieces in the model (if a piece is already flat, it will not appear in this list). The piece ID is system assigned, however the piece name can be user defined.
