Issues Descriptions

What are units for 'angle' field in TessParametersStruct

  • Key: CAD-15
  • Legacy Issue Number: 4538
  • Status: closed  
  • Source: Westinghouse Electric ( Jim Jones)
  • Summary:

    adGeometry IDL comment documents the 'angle' field in CadGeometry.TessParametersStruct
    as "deviation between normals of facets".

    Neither the IDL nor the CAD Services spec. indicate what angular units should be used.

  • Reported: CAD 1.0b1 — Mon, 27 Aug 2001 04:00 GMT
  • Disposition: Resolved — CAD 1.0
  • Disposition Summary:

    This oversight was corrected by indicating the required use of degrees for angle units.

  • Updated: Fri, 6 Mar 2015 20:58 GMT

TessellationStruct normals field should be VectorStructSeq

  • Key: CAD-14
  • Legacy Issue Number: 4537
  • Status: closed  
  • Source: Westinghouse Electric ( Jim Jones)
  • Summary:

    The type of the 'normals' field in TessellationStruct should be VectorStructSeq
    instead of PointStructSeq.

  • Reported: CAD 1.0b1 — Mon, 27 Aug 2001 04:00 GMT
  • Disposition: Resolved — CAD 1.0
  • Disposition Summary:

    Agreed. IDL modified.

CadBrep Edge.nearest_points function needs clarification

  • Key: CAD-12
  • Legacy Issue Number: 4493
  • Status: closed  
  • Source: Anonymous
  • Summary:

    CadBrep Edge.nearest_points function needs clarification for
    'nearest_points' argument.

    How are the nearest_points defined? It is declared as a PointStructSeq,
    but no further details are provided. Will there always be 2? Is the
    first point of the sequence a point on the given edge and the second
    point a point on the edge corresponding to the input argument? What is
    the expected behavior if there are multiple locations that the 2 edges
    have an identical minimum distance?

CadBrep Edge.nearest_points function incorrect

  • Key: CAD-11
  • Legacy Issue Number: 4492
  • Status: closed  
  • Source: Anonymous
  • Summary:

    CadBrep Edge.nearest_points function incorrectly defines the
    'nearest_points' argument as 'in'.

    CAD Services spec documents Edge.nearest as 'Determines the minimum
    distance, and corresponding closest points, between this Edge and the input
    Edge. The returned value is the minimum distance'. The 'nearest_points'
    argument should be declared as 'out'.

  • Reported: CAD 1.0b1 — Mon, 6 Aug 2001 04:00 GMT
  • Disposition: Resolved — CAD 1.0
  • Disposition Summary:

    Resolved through removing the nearest_points operation. See issue 4493.

  • Legacy Issue Number: 4489
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Binding for Face.nurbs_representation needs major design overhaul or
    removal.

    IDL indicates the function returns a CadUtility.NurbsSurfaceStruct. A
    simple NURBS surface structure cannot represent arbitrary faces w/
    irregular boundaries, both outer and inner.

  • Legacy Issue Number: 4488
  • Status: closed  
  • Source: Anonymous
  • Summary:

    CAD Services specification needs to clarify 'exact' for
    nurbs_representation functions.

    nurbs_representation indicates that if the NURBS is exact, then tolerance
    is returned as negative value. Is that exact geometrically or exact
    geometrically AND parametrically?

  • Status: closed  
  • Source: Anonymous
  • Summary:

    Surface.nurbs_approximation should have 'tolerance' argument declared as
    'inout' instead of 'in'.

    CAD Services specification indicates that 'If nurbs representation is
    exact, tolerance will be returned as a negative'. By the way, the 'NURBS'
    acronym should be capitalized in the spec and IDL when used in this
    context.

Incompletely specified operations - issue

  • Key: CAD-43
  • Legacy Issue Number: 4985
  • Status: closed  
  • Source: NASA ( Russ Claus)
  • Summary:

    Mikhail Kazakov mentioned that some of the Cad Services interfaces may be under-specified. Here is a list of operations needing additional documentation:
    1. CadMain:: open_model( Â…) - the question involves whether this operation loads the specified model into memory or are all the available models in memory and the open_model() operation merely returns an object reference to the model.

    Recommendation: the documentation should include the following: The open_model() operation loads the specified model into memory and can be unloaded by invoking close_model() on the Model object reference.

    2. CadMain:: top_level_entities (in CadUtility::TypeCodeSeq entity_types) - what happens when an empty TypeCodeSeq is passed? One could respond with all top level entities or none.
    Recommendation: Documentation shall state that an empty TypeCodesSeq will result in a system exception (BAD_PARAM).

    3. unsigned long unique_entities_count (in CadUtility::TypeCodeSeq entity_types) raises (NotValidCadType, CadUtility::CadError); - what happens when an empty TypeCodeSeq is passed? One could respond with all entites or none.
    Recommendation: Documentation shall state that an empty TypeCodesSeq will result in a system exception (BAD_PARAM).

    4. CadFoundation::EntitySeq unique_entities (in CadUtility::TypeCodeSeq entity_types) raises (NotValidCadType, CadUtility::CadError); – what happens when an empty TypeCodeSeq is passed? One could respond with all entites or none.
    Recommendation: Documentation shall state that an empty TypeCodesSeq will result in a system exception (BAD_PARAM).

  • Reported: CAD 1.0b1 — Mon, 18 Mar 2002 05:00 GMT

    The identified recommendations were agreed.

Several properties in the CadBrep::PropertyStruct need clarification.

  • Key: CAD-42
  • Legacy Issue Number: 4653
  • Status: closed  
  • Source: NASA ( Russ Claus)
  • Summary:

    double inertial_moment_spherical;
    double gyration_radius_spherical;
    CadUtility::VectorStruct first_moments_centroidal;
    CadUtility::VectorStruct inertial_moments_centroidal;
    CadUtility::VectorStruct inertial_products_centroidal;
    CadUtility::VectorStruct principle_moments_centroidal;
    CadUtility::VectorStruct gyration_radii_centroidal;

    are unclear.

    Jim Stevens identified the following:

    The "centroidal" moments are the various mass properties with respect to the center of mass for the body. This is the more "typical" case for mass properties. They correspond to similar mass property calculations in the structure that are with respect to a specific coordinate system.
    Principle moments are moments inertia along the principle axes through the center of gravity of an object.
    When defining a moment of inertia around an arbitrary axis thru the center of mass you end up with product terms. There is
    one axis definition for which the product terms are zero, which is called the principle axis and the moments of inertia when
    using that axis definition are the principle moments.
    Radius of gyration is related to the moments of inertia and the mass along each axis.
    I am not sure about the meaning of first moments. I am pretty sure that inertial_moment_spherical and
    gyration_radius_spherical have to do with representing the model with a single sphere that would have
    the same overall inertial characteristics as the analyzed body.
    Jim Stephens

    Based on Jim's comments I am not certain that we need the first moments or the spherical inertial moment and gyration radius.

Entity.Position() returns PointStructure instead of TransformationStructure

  • Key: CAD-33
  • Legacy Issue Number: 4572
  • Status: closed  
  • Source: Open Cascade ( Mikhail Kazakov)
  • Summary:

    Replace
    CadUtility::PointStruct position () raises (CadUtility::CadError);
    // Returns a struct of the coordinates of a single, reference location on
    // the entity that should be unique relative to neighboring entities.
    method by
    CadUtility::TransformationStruct location () raises (CadUtility::CadError);
    // Returns a struct of the applied transformation, which represents
    // the location (position, turn, scale) of the entity according the global coordinates

    In that case, we will be able to refer the entity according any other entities.
    This method doesn't return the "last applied transformation", but "the superposition
    of all applied transformations". In that case, location of the entity in 3D space will be returned.

  • 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.

CadSystem Properties issue

  • Key: CAD-29
  • Legacy Issue Number: 4564
  • Status: closed  
  • Source: Anonymous
  • Summary:

    In the CadServer interface we have the ability to inquire launch
    properties for the CadSystem, and then pass in a set of properties
    when we call connect() or connect_with_password().

    Once the CadSystem is running we do not have a way to query or
    change the properties.

    As an example - UG has a property for the search path for files.
    You can set this property when you initially start up the CadSystem.
    If it needs to be changed during a session the only choice is to
    shut down the CadSystem with disconnect() then call connect()
    again.

    Also, if you connect to an already running CadSystem you
    cannot determine what properties were used during the original
    connect().

    I think I would propose adding something like "get_properties"
    and "set_properties" for the CadSystem interface. These calls
    would basically allow a query and update of the properties
    provided to the CadServer via the connect() calls.

    CosPropertyService::Properties get_properties();
    void set_properties( in CosPropertyService::Properties props );

how to add new topological entities to existing model with sharing of exist

  • Source: Open Cascade ( Mikhail Kazakov)
  • Summary:

    3. It is not clearly described in the specification document, how to add new topological entities to existing model with sharing of existing entities.
    Let's say we have 2 vertexes already created and we would like to add an edge.
    While implementing EntityFactory interface, a developer have to care about this sharing. Otherwise vertexes won't be shared.
    And from my point of view we have to speak about that in the document.
