Feature Operations
Methods and Properties Introduced:
The method IpfcSolid.ExecuteFeatureOps() causes a sequence of feature operations to run in order. Feature operations include suppressing, resuming, reordering, and deleting features. The optional IpfcRegenInstructions argument specifies whether the user will be allowed to fix the model if a regeneration failure occurs.
 |
Regenerating models in resolve_mode is not supported. As a result, the method IpfcSolid.ExecuteFeatureOps() is not supported anymore.
|
You can create an operation that will delete, suppress, reorder, or resume certain features using the methods in the classIpfcFeature. Each created operation must be passed as a member of the IpfcFeatureOperations object to the method IpfcSolid.ExecuteFeatureOps().
Some of the operations have specific options that you can modify to control the behavior of the operation:
• Clip—Specifies whether to delete or suppress all features after the selected feature. By default, this option is false.
Use the properties IpfcDeleteOperation.Clip and IpfcSuppressOperation.Clip to modify this option.
• AllowGroupMembers—If this option is set to true and if the feature to be deleted or suppressed is a member of a group, then the feature will be deleted or suppressed out of the group. If this option is set to false, then the entire group containing the feature is deleted or suppressed. By default, this option is false. It can be set to true only if the option Clip is set to true.
Use the properties IpfcSuppressOperation.AllowGroupMembers and IpfcDeleteOperation.AllowGroupMembers to modify this option.
• AllowChildGroupMembers—If this option is set to true and if the children of the feature to be deleted or suppressed are members of a group, then the children of the feature will be individually deleted or suppressed out of the group. If this option is set to false, then the entire group containing the feature and its children is deleted or suppressed. By default, this option is false. It can be set to true only if the options Clip and AllowGroupMembers are set to true.
Use the properties IpfcSuppressOperation.AllowChildGroupMembers and IpfcDeleteOperation.AllowChildGroupMembers to modify this option.
• KeepEmbeddedDatums—Specifies whether to retain the embedded datums stored in a feature while deleting the feature. By default, this option is false.
Use the property IpfcDeleteOperation.KeepEmbeddedDatums to modify this option.
• WithParents—Specifies whether to resume the parents of the selected feature.
Use the property IpfcResumeOperation.WithParents to modify this option.
• BeforeFeat—Specifies the feature before which you want to reorder the features.
Use the property IpfcReorderBeforeOperation.BeforeFeat to modify this option.
• AfterFeat—Specifies the feature after which you want to reorder the features.
Use the property IpfcReorderAfterOperation.AfterFeat to modify this option.
