I have labelled the shift directions as u & v (not x & y, as Autodesk labels them) because the directions relate to the axis of the line, not the whole pattern - so a vertical line would have a u offset measured vertically (labelled as x direction by Autodesk, which is confusing).Ī typical staggered tile pattern (stretcher bond) consists of : Line starts repeating (measured in the direction of the line) isĪlways a minus value. Pen up = length of gap in the line before the next segment of the.Pen down = length of solid line measured in the direction of the line ( optional - it draws a continuous line if omitted).Shift v (y axis of line) = offset distance of start of repeat line measured perpendicular to start of line.The Shift values are measured from the start of the line, not from the setout point. Shift u (x axis of line) = offset distance of start of repeat line measured parallel to start of line.Origin y = vertical distance of start of line from setout point (always orthogonal).

Origin x = horizontal distance of start of line from setout point (always orthogonal).

Angle = angle of line from horizontal measured in an anti-clockwise direction.

The pattern file is a text file, saved with a '.pat' extension.ĭefinition of units (important for metric):Įach pattern definition has an * prefixed header : a title and description separated by a comma
