This part of ISO 10303 specifies the interpretation of the itegrated resources to satisfy the requirement

for the definition of a face with explicit topological bounds and fully defined geometry.

The following are within the scope of this part of ISO 10303:

3D geometry;

B-spline curves and surfaces;


elementary curves;

elementary surfaces;



sculptured surfaces;

surface curves referencing pcurves;

swept surfaces;

twisted curves;

unbounded geometry;

geometric transformations;

use of topology to bound geometric entities.

The following are outside the scope of this part of ISO 10303:

2D geometry other than for the definition of a pcurve in the parameter space of a surface;

bounded curves other than polylines and B-spline curves;

bounded surfaces other than B-spline surfaces;

offset curves and surfaces.

Add to cart this standard

This collection is a standard for the exchange of product model data (STEP) module and resource library (SMRL). It is intended for those who are considering adopting ISO 10303 modular application protocols, application modules, and resource parts, or systems built on them, for product data representation …
