RecordGeometryAction Class Reference

This action records the current mould geometry being used by a particular mould node. Once recorded this allows the geometry to be changed. During undo the old geometry will be replaced but not initialised. More...

static ActionCode Init (Operation *const pOp, ActionList *pActionList, NodeMould *const pMould, Action **NewAction)
 This simple action saves away the current mould space (geometry) defined by this mould object. The mould space may then be deleted externally and replaced with another. During undo the new space will be recorded and the old space rebuilt.
static ActionCode DoRecord (Operation *const pOp, NodeMould *const pMould)
