Issue 4570: CadFoundation::Entity interface                                                                                                                                                                         (cad-ftf)

Nature: Uncategorized Issue
Severity: 
Summary: There is no "3D Location" function in Entity interface.
There is only Entity.Position(), which returns PointStructure,
but it is not enough to describe a 3D transformation.
It's necessary to return TransofmrationStruct from such a function.
It's necessary also to mention, that Entity interface has a method for
transformation.

However, if Position() has another goal, than 3D location of Entity, it
shall be described in the document.

Resolution: see above
Revised Text: The IDL and supporting text in Section 2.3.2 were modified as:
reference_position	Returns a struct (CadUtility::PointStruct) of the coordinates of a single, reference location on the entity that is unique relative to neighboring entities.
global_location	Returns a struct (CadUtility::TransformationStruct) that provides global coordinate location information.

Actions taken:
September 20, 2001: received issue
July 5, 2002: closed issue
Discussion: 
The position functionality was not clearly defined in the IDL or the document. It was agreed to relabel the position operation to reference_position and provide an additional operation global_location that provides a TransformationStruct with global coordinate information

        Hello,

I'd like to post a new issue:

CadFoundation::Entity interface.
There is no "3D Location" function in Entity interface.
There is only Entity.Position(), which returns PointStructure,
but it is not enough to describe a 3D transformation.
It's necessary to return TransofmrationStruct from such a function.
It's necessary also to mention, that Entity interface has a method for
transformation.

However, if Position() has another goal, than 3D location of Entity,
it
shall be described in the document.


Regards.
Misha
