ISO 10303-518:2011 specifies the integrated resource constructs for Mechanical design shaded presentation.
ISO 10303-518:2011 specifies the use of ISO 10303 application interpreted construct satisfying the requirements for mechanical design shaded presentations. ISO 10303-518:2011 is mainly based on ISO 10303-46. Point, curve, and surface styles can be specified for the constituents of any shape representation. Shading and surface characteristics, such as reflectance and transparency are included. The concept of layers is out of scope, as is the representation of text.
