Tubulaire

Tubulaire is a term used in several disciplines to denote something shaped like a tube. Originating from the French adjective tubulaire, it is commonly encountered in technical writing, anatomy, architecture, and geometry, where it serves as either a descriptive modifier or part of a compound name in French-language texts. In English-language contexts, the corresponding adjective is tubular.

In geometry, a tube around a space curve is the set of points at distance less than

In biology, tubular describes organs and tissues that are cylindrical in form. Examples include renal tubules

In engineering and architecture, tubular design favors hollow, cylindrical members to reduce weight while maintaining stiffness.
