Not all dimension types have * feature lines. The actual start and end of feature lines is calculated from dimension style * properties (offset from feature point to start of feature line, height of crossbar, and height * of feature line past crossbar, for example in linear dimensions) * * - "crossbar" refers to the perpendicular line (usually with arrows at each end) between feature * lines on linear dimensions */ class PCB_DIMENSION_BASE : public BOARD_ITEM { public: PCB_DIMENSION_BASE( BOARD_ITEM* aParent, KICAD_T aType = PCB_DIMENSION_T ); bool IsType( const KICAD_T aScanTypes[] ) const override { if( BOARD_ITEM::IsType( aScanTypes ) ) return true; for( const KICAD_T* p = aScanTypes; *p != EOT; ++p ) { if( *p == PCB_LOCATE_GRAPHIC_T ) return true; } return false; } void SetParent( EDA_ITEM* aParent ) override; /** * The dimension's origin is the first feature point for the dimension.
