Description

The look of a contact print pulled off a drafting original: every line comes back white on a saturated process blue, with dimension arrows on extension lines, evenly hatched section cuts and a ruled title block in the lower corner. Line weight does all the work — there is no shading, no gradient and no second colour. It suits posters, covers, packaging and identities that should read as engineered rather than drawn.

Custom Style Items

Drafting Sheet Structure
Inset ruled border; lower-right title block with drawing number, scale, date, drawn-by, and revision; revision table stacked above when needed.
Dimensioning Logic
Dimensions sit outside objects on thin extension lines; arrowheads at both ends; numeral breaks the dimension line at midpoint.
Section Convention
Every cut section receives evenly spaced 45-degree hatching; solidity is never described with shading.
Type Placement
Short, letterspaced labels and numerals only; contained within title-block cells, dimension breaks, or circled detail bubbles.
Enamel Pin Translation
Use a hard-enamel-like, saturated ground with recessed pale technical linework, raised metal-style borders, and simplified legible drafting symbols.
