Alternate Entities to Use When Exporting Excluded IGES Entities
Unless the alternate entity is also excluded, the alternate entities for excluded IGES entities are as follows:
| IGES Entity | Alternate If Excluded |
|---|---|
| 100. Circular Arc | 126. Rational B-spline Curve |
| 102. Composite Curve | Individual component entities |
| 104. Conic Arc | 126. Rational B-spline Curve |
| 106. Copious Data | 110. Line(s) |
| 108. Plane (Bounded) | 230. Sectioned Area |
| 116. Point | 110. Line (zero length) |
| 126. Rational B-spline Curve | 106. Copious Data |
| 128. Rational B-spline Surface | 126. Rational B-spline Curves (rule lines) |
| 142. Curve On Surface | B-spline Surface boundaries are ignored |
| 144. Trimmed Surface | Grouped holes are exported as Sectioned Area entities (type 230) |
| 212. General Note | 106. Copious Data |
| 230. Sectioned Area | Bounding elements area pattern |
| 308. Subfigure Definition | Individual component entities |
| 314. Color Definition | Standard colors are used |
| 408. Singular Subfigure Instance | All cells are dropped (placed as individual entities in the IGES file) |
