<p>This part of ISO 10303 specifies the interpretation of the integrated resources to satisfy requirements for</p>
<p>the description of geometric shapes by means of non-manifold surface models.</p>
<p>The following are within the scope of this part of ISO 10303:</p>
<p><b>— </b>3D points;</p>
<p><b>— </b>points defined in the parameter space of curves or surfaces;</p>
<p><b>— </b>3D curves;</p>
<p><b>— </b>curves defined in the parameter space of surfaces;</p>
<p>NOTE - Such curves are also known as pcurves or cons, which are acronyms for parametrised curve</p>
<p>and curve on surface.</p>
<p><b>— </b>the elementary curve types line, circle, ellipse, parabola, and hyperbola;</p>
<p><b>— </b>intersection curves;</p>
<p><b>— </b>polylines that consist of at least three points;</p>
<p><b>— </b>the elementary surface types plane, cylinder, cone, torus, and sphere;</p>
<p><b>— </b>swept surfaces created by rotation or linear extrusion of a curve;</p>
<p><b>— </b>sculptured curves and surfaces;</p>
<p><b>— </b>trimming of curves and surfaces using topological entities;</p>
<p><b>— </b>composition of curves and surfaces using topological entities;</p>
<p><b>— </b>replication of curves, surfaces, and surface models;</p>
<p><b>— </b>3D offsets of curves and surfaces;</p>
<p><b>— </b>non-manifolds.</p>
<p>The following are outside the scope of this part of ISO 10303:</p>
<p><b>— </b>unbounded geometry;</p>
<p><b>— </b>self-intersecting geometry;</p>
<p><b>— </b>geometry in a 2D cartesian coordinate space;</p>
<p><b>— </b>replication of points;</p>
