In the admin area under Folding Patterns, you can create your own folding patterns.
This is especially helpful for more complex folding processes that Keyline does not cover by default.
Choose a meaningful and unique name and select the appropriate fold type.
(The folding pattern will later be listed in this category during calculation.)
Folding steps specify the sequence in which a sheet must be folded to achieve the desired result.
Keyline uses its own notation for this, loosely based on the JDF folding scheme.
There are essentially three variables:
U (Up): The relative portion of the unfolded (!) sheet that is folded from left to right.
→ Requires the relative portion to be specified (e.g. 1/2, 1/3, 1/4, etc.).
→ Example: U1/3 = Fold one third of the original sheet from left to right.
D (Down): Similar to U, but the sheet is folded from the left underneath the right-hand side.
→ Example: D1/2 = Fold one half underneath the other half.
R (Rotate): Rotate the folded sheet clockwise.
→ Requires the angle of rotation to be specified (90, 180, 270).
→ Example: R90 = Rotate the entire sheet 90 degrees clockwise.
Important:
The individual steps must be separated by a semicolon (;).
Commas, colons or other separators are not permitted.
Example:
U1/6;U1/6;R90;D1/2
Fold one sixth from left to right.
Then fold another sixth to the right (the length remains the same, because calculations always refer to the unfolded sheet).
Rotate the folded sheet 90 degrees clockwise.
Then fold half from the left underneath the right-hand side.
This flexible folding notation lets you represent almost any fold type individually and precisely in Keyline.
