BTP
A is for · Jeremy Perrodeau, Guillaume Grall · 2011

A strictly angular typeface derived from AutoCAD's default stroke font, built with no curves and accompanied by a set of construction-themed pictograms.
About
Originating from a typographic experiment in issue #195 of the French magazine Étapes in 2011, BTP was developed by Jeremy Perrodeau and Guillaume Grall as a formal response to the lettering conventions of architectural drawing software. The family comes in Light and Normal weights, each with a rotated variant serving as an italic substitute, plus seven interpolated weights in an extended family. A set of around 30 pictograms, including brick walls and road patterns, can be used to create borders and decorative frames in the manner of traditional metal ornaments.
Classification
BTP is derived from the default AutoCAD stroke typeface, resulting in a strictly angular, single-stroke-inspired geometric construction with no curves. Its pictogram set and rotated italic variants place it firmly in the display category.
