Geometry Transfer Limitations

The following elements have not been implemented:

• B-spline Pole (Type 21)

• B-spline Surface Header (Type 24)

• B-spline Surface Boundary (Type 25)

• B-spline Knot (Type 26)

• B-spline Curve Header (Type 27)

• B-spline Weight Factor (Type 28)

The Curve element (Type 11) and Conic element (Type 13) are treated as a series of straight segments and not as curves.

The translator does not deal with warped surface (double curved surfaces, typically defined by B-Splines or other curves) and volumes defined by boundary elements within the Surface Header (Type 18) or Solid Header (Type 19).

Type of Surface

Type of Solid

3D Lines are ignored.

Holes defined independently and not as part of a cell are ignored.

Holes made from negative cones are ignored.

Some wedges have been implemented using a different method; instead of two 3-sided shapes and four ruled lines, a rectangle and line can be used with four ruled lines.

Shared Cell Definition and Shared Cell Instances have not been implemented.

Feature Solids, Smart Solids and Smart Surfaces are not supported.
