it is changed in order to avoid side-effects in GH-definitions.
(Inherited from CroSec.) |

(Inherited from CroSec.) |
 | defaultGuid |
return the cross sections default guid

set the material based on the material identifier and a mapping from material identifiers to indexes
(Inherited from CroSec.) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |

returns true if cross section has default properties

set the material identifier and the material reference of the cross section
(Inherited from CroSec.) |
