Sheet Lightning has both a parametric (i.e. design by typed dimension values only) and a full 3D CAD
environment (i.e. using typical 3D CAD design tools). A high proportion of design using Sheet Lightning
employs the simple use of the parametric design library. The normal procedure for parametric design is as
follows:
Procedure for using parametric design:
1. Open the parametric library browser and search the directories for the required design.
2. Scale it (sometimes) to achieve approximate sizes.
3. Select the parameters you wish to change.
4. Type in the new dimension values.
5. Unfold the design.
6. Arrange the unfolded patterns/templates as required.
7a. Print the pattern full size.
8a. Create the physical design using the printed patterns
or:
7b. Export the data to a CAD or CAM system
8b. Manufacture the design.
Procedure for using CAD design:
1. Create a new/empty design.
2. Add the new objects by positioning center line ends.
3. Connect object nodes to form intersections (while creating or moving the objects).
4. Edit the parts sections and details using the part editor.
5. Weld the design.
6. Measure and check the design (using tools - if required)
7. Unfold the design.
8. Print or export (as with parametric design - above).
9. Manufacture the design.
10. Snap images, list reports and document (if required).
Alternatives are:
1. Load an existing design and modify it using the CAD tools, perhaps by moving objects, deleting objects,
creating new objects, disassemble and/or reassemble a design, copy and pasting designs together, alter
the matching of objects.
2. Design using construction lines (or whole frames).
3. Convert the CAD design to a parametric design, edit it and add it to the parametric library.
