Templates

Templates are required for plates which need mechanical processing (bending or forming) to obtain the desired shape.

We need templates in the following situations:

• Single curvature (bending) with constant radius - no template required, give bending info on plate.
• Single curvature (bending) without constant radius - 1 template required.
• Double curvature (forming) - minimum 3 templates required.

Template types

• Bow Fashion - for plates which are on the center line and have symmetry around the center line (for example a bow cone)
• Standard - all other plates:
  • Create the templates on the reference lines, as perpendicular to the surface as possible, or if this is not applicable:
  • Use Auto-Level

Template label

• Plate Name
• Marking Line Name
• Bracket Angle

Template name is plate name + reference line name or, when using Auto-Level, plate name + T1 (T2, T3, etc.)

Template style is Plate

Edge margin 50mm

    • Type Bow Fashion for templates with symmetry at CL, or
    • Type Standard for templates with non-symmetry at CL, then
    • use reference lines for templates
    • use Auto-Level templates only when:
      • the shape is not sufficient defined with reference lines
      • the angle of the templates at the plate becomes to small
    • Style Plate
    • Template name is plate name + reference line name, or
    • Template name is plate name + marking line name (T1, T2, etc.)
    • No Edge Margin
    • Indicate sightline angle
    • Sightline arrow direction to CL or UP
    • Bow fashion CL template to have an arrow indicating the top
