A check-mark-like tick with a long arm, carrying surface texture requirements.
Also known as: Roughness symbol, Tick with a long arm, Check mark drawing symbol
A tick with an extended arm carries surface texture requirements. Its variants say whether material must be removed: a circle in the V forbids machining, a bar across it requires it.
Carries the surface texture requirement for a face, with roughness values and process notes written around its arms.
Contexts: Technical drawing
Changes meaning with a small addition: a circle in the V forbids material removal, and a horizontal bar across the V requires it.
Contexts: Technical drawing
Is governed by ISO 1302, which sets out the symbol and the placement of the values around it.
Contexts: Technical drawing
A short stroke rising to meet a longer stroke at an acute angle, forming an asymmetric V whose right arm extends well beyond the left, sometimes with a horizontal bar across the top.
