The vector stencils library "Basketball courts" contains 8 templates of basketball court diagrams.
"In basketball, the basketball court is the playing surface, consisting of a rectangular floor with tiles at either end. In professional or organized basketball, especially when played indoors, it is usually made out of a wood, often maple, and highly polished. Outdoor surfaces are generally made from standard paving materials such as concrete or asphalt (i.e. blacktop/tarmac)." [Basketball court. Wikipedia]
The example "Design elements - Basketball courts" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Basketball solution from the Sport area of ConceptDraw Solution Park.
