TYPICAL APPLICATIONS
Bulk Materials Handling - hoppers and chutes. Fluids Conveying - ducts, transitions, - transformers, hoods, shrouds. `Industrial strength' structures - thick plate.

TECHNICAL DESCRIPTION
Uses triangulation development method, two setout types . Covers finite thickness 3D plate structures. Stucture connects between user-located shapes. Shapes are `rectircles', i.e. round cornered rectangles. Rectircle describes circle, rectangle, obround, etc. Elliptical cross-sections also provided for, and ... A `half-shape' may be defined at one end. Optional automatic mitreing at ends, for improved flow. Optional prismatic collars, mandatory when with mitres. Automatic compensation for tightly pressed thick plate.

DATA REQUIREMENTS
Inlet and outlet cross-sectional shape parameters.
Position and direction of outlet relative to inlet.
Collar lengths and mitreing options.
Plate thickness.
Longitudinal joint locations (up to 8 joints)
Number of strakes in main body (up to 4 strakes)
Green, and provision for longitudinal seam offsets.
Selection of development type.

OUTPUT
Patterns in any of the following forms ...
FastCAM file
DXF (2D) file
Coordinate Table
A 3D DXF file describing the complete structure.
