CadConnection, CadSystem: Avaliable_models() enhancement

    Title: CadConnection, CadSystem: Avaliable_models() enhancement
    Source:
    Markus Helmke, Produktionstechnisches Zentrum (PTZ)
    Technische Universität Berlin
    Email: markus.helmke@ipk.fhg.de

    Summary:

    The method "available_models()" provides access to models available to the active CAD System and returns all available models in a list. Up to now the method does not take into account how the models are structured on the server side. When a user selects a model it would be helpful to navigate through the tree structure of the servers file system. A similar problem is the specification of a users file name in that moment when he wants to use "save_model_as()" or "create_model()".
    The proposed methods, data structures and definitions aim to improve navigation capabilities for both systems and users when accessing models. For various reasons a native CAD-system normally is able to access different directories which are presented also to the user. This is to let him structure his work but also in order to offer templates that ease the design process, because in most cases designer aren't starting from scratch, but they are provided with templates that cover predefined parameters or a special design philosophy.
    Assuming a user wants to store, create, or open a model on the (maybe remote) machine running the Cad-Services he expects something like a "FileChooser"-dialog. The method "available_models()" was not designed to support such functionality and therefore needs to be extended.
    The proposed methods allow for implementing the intended functionality because they represent an essential subset of methods needed to do the following:

    • Navigation (get_root_directories(), get_models_and_folders(), get_parent_directory())
    • Create new subfolder (create_new_folder())
    • Providing information to choose a file or folder on the client side (get_models_and_folders())
      The concept provides the possibility not to expose the whole file system to the user by using "root_directories". Every directory can serve as root directory and thus only its subdirectories are exposed to the user. The user starts navigation in the one of the roots.
      The methods were taken from JAVA's abstract class "javax.swing.filechooser.FileSystemView" which serves as "JFileChooser's gateway to the file system" and as such promise to be sufficient. Additionally IWF has implemented against the proposed CAD-Services enhancement with success.

    Revised Text:
    The following typedefs, struct and operations are added to the CadConnection module respectively to the CadSystem interface:

    module CadConnection
    {

    struct Path

    { boolean is_dir; // Indicates whether Path represents a file or a directory string path; // Canonical, absolute, and unique path representing a file or // a directory }

    ;

    typedef sequence<string> RootsList;
    typedef sequence<Path> PathList;

    interface CadSystem

    { // Creates a new folder in a given directory. // param parent_dir: The (canonical, absolute, and unique) path of the // directory, in which the folder will be created. This must be either // one of the root directories (see get_root_directories()) or a // directory that exists in one of the root directory's subdirectories // param folder_name: The name of the folder to be created. It must be a // valid and a not already existing name. // raises CadUtility::CadError: If there was an error in creating the // folder. void create_new_folder(in string parent_dir, in string folder_name) raises (CadUtility::CadError); // Returns a list of (canonical, absolute, and unique) pathnames repre- // senting the root directories. In a root directory or in any other // subdirectory, model files can be found. // return: List of pathnames representing root directories. RootsList get_root_directories(); // Returns a list of subdirectories and model files of a given directory. // param directory: (canonical, absolute, and unique) path of the // directory from which to get the list of subdirectories and model // files. This must be either one of the root directories or a subdirectory. // return: A list representing subdirectories and/or model files // of the given directory. // raises CadUtility::CadError If there was an error retrieving the list. PathList get_models_and_folders(in string directory) raises (CadUtility::CadError); // Returns the parent directory of a given directory. // param directory: (canonical, absolute, and unique) path of the // directory from which to get its parent directory. The given directory // should be a subdirectory of one of the root directories. // return: The path of the parent directory. // raises CadUtility::CadError If there was an error retrieving the // parent directory. string get_parent_directory(in string directory) raises (CadUtility::CadError); }

altering the use of EntitySeqs to LongSeqs

  • Key: CAD12-1
  • Legacy Issue Number: 5844
  • Status: closed  
  • Source: CAxOPEN GmbH ( Andreas Korn)
  • Summary:

    I suggest altering the use of EntitySeqs to LongSeqs - essentially to use Unique IDs as identifiers. [In places like: Model::delete_entity(), EntityGroup::add_entities(), EntityGroup::remove_entities()] I see there 2 main problems: 1. I don't see that it is really neccesssary to use the (in this case Entity objects) CORBA objects to identify an object. unique_id's could always be used. -> Less traffic and a lot easier to map. Besides: how much sense does the UidUnsupported exception make? unique ids can always be created. 2. The required mapping especially on the server side is somewhat tricky and not the fastest. You would have to map the CORBA objects to the implementation objects. Nasty thing to do.

Model Instances vs. Top-Level Entities

  • Key: CAD11-19
  • Legacy Issue Number: 5747
  • Status: closed  
  • Source: NASA ( Russ Claus)
  • Summary:

    The distinction between model instances and top-level entities was unclear to me, especially so given my task of trying to write a general purpose tool to "import" arbitrary CAD models into CFD-GEOM via the CAD Services interface. A Model can contain zero or more ModelInstances, and this provides support for assemblies. At the same time, certain entities in a Model are designated as top-level entities, which also brings to mind the concept of a composition or assembly.

  • Summary:

interface Parameter

  • Key: CAD11-34
  • Legacy Issue Number: 5935
  • Status: closed  
  • Source: Technical University Berlin ( Markus Helmke)
  • Summary:

    The interface Parameter provides four functions · string get_expression() raises (CadUtility::CadError); · void set_expression(in string e_value) raises (CadUtility::CadError); // operations to allow an expression that may drive geometry

    · CadUtility::EntityAttrib get_value() raises (CadUtility::CadError); · void set_value (in CadUtility::EntityAttrib value) raises (CadUtility::CadError); // operations providing access to parameter value Actually “Parameter” is an easy interface. But since we have seen different implementation approaches and since it was not clear for us in every case too what should be handed over to the set-methods and what could be retrieved by the get-methods I write down our assumptions and hope that it will be corrected if that was not the approach you have had in mind: A parameter covers expressions like “a=6” or “a=b+c”, where “a” is the “name” of the expression. getValue() therefore will return the recursive computed value in the case of “b+c” or an error when there is a problem with the computation. In case of “6” getValue() will just return the value “6”. setValue() allows to set a value if the value of “is_read_only” has the value “false”. The type of the handed over value must match the type of CadUtility::EntityAttrib stored by parameter. In the case of “a=6” “is_independent” keeps the value true. In the case “a=b+c” “is_independent” turns to the value “false”. It is a question whether handing over a value like “8” should be allowed at all when the parameter carries an non numeric expression. getExpression() is similar to getValue() with the difference that the return type is a string. setExpression() allows to set expressions like “d+e” or “8”. The values of “is_independent” and “is_read_only” have to be set accordingly. Expression like “a=d+e” and “a=8” should be possible but internally the expression is parsed and “a=” is ignored. Expression like “b=d+k” should be forbidden because they provide a back door to define completely new parameter when name is set to “b”. If this also has been intended this should be made clear. But I guess this would require extra methods that allow to define parameter. Summing up it is actually no problem to omit the value-methods The “expression”-methods can take over the task to handle values because these also can be represented by expressions like “8”.

"Cadsystem" interface issue

  • Key: CAD11-25
  • Legacy Issue Number: 5753
  • Status: closed  
  • Source: Anonymous
  • Summary:

    The interface "Cadsystem" provides access on a "CadUserInterface" by the
    method

    boolean is_interactive(out CadUserInterface gui);

    Normally loading a model in the CAD engine and showing it with the editor
    are two different tasks.
    "create_model" and "open_model" obvioulsy are related to CAD-Engine
    activity. GUI activities like showing, hiding etc. are not mandatory
    implicated. If methods like "create_model" and "open_model" are intended not
    to include GUI operation then functionality to control the
    "CadUserInterface" is missing.
    Therefore the following function would be very helpful (They assume that a
    model is already loaded by the CAD engine):

    createWindow(model) // Creates a window and put it in the foreground
    hideWindow(model) // hides an existing window but doesn't
    delete it
    foregroundWindow(model) // put an existing (even if hided) window in the
    foreground
    deleteWindow(model) // delete the window and the corresponding window
    data structure but NOT the model within the CAD engine

    Every model should throw a "ModelNotLoadedException" if the model is not
    loaded.

    Summing up this should allow for a separated control of activities within
    the CAD-engine and the editor.

"Entity-Types"

  • Key: CAD11-24
  • Legacy Issue Number: 5752
  • Status: closed  
  • Source: Anonymous
  • Summary:

    In some methods (mainly Model-Interface) "Entity-Types" are demanded as an
    selection mechanism to select appropriate entities. Example:

    CadFoundation::EntitySeq top_level_entities (
    in CadUtility::TypeCodeSeq entity_types)

    But the CAD-Services provide no opportunity to implement a method that
    allows to ask for these entity types that are supported by the respective
    CAD-System. But in our mind it is up to the CAD-System and thus to the
    CAD-Services to provide such information

  • Summary:

    The Edge::start_parameter() and Edge::end_parameter() operations return the "curve parameter corresponding to the start (end) vertex". I suppose this is referring to the parametric distance along the underlying curve, but it's unclear because of the sort-of generic use of the word "parameter".

Tessellation Types

  • Key: CAD11-22

  • Summary:

    For example, consider the requirements for calling Body::tessellate():
    ConnectedFaceTessellationStruct
    tessellate(in TessType t_type,
    inout TessParametersStruct params,
    out boolean flag);

    The first argument (the tessellation type) can be one of two enumerated values, WIREFRAME or VISUALIZATION. Nowhere in the specification is any hint given as to the difference between these two settings. One might guess that the VISUALIZATION tessellation type produces a larger number of triangles, but to what degree? Is it implementation-dependent?

    An empty TypeCodeSeq in Model::bounding_box() and Model::top_level_entities() will be handled differently according to the comments in the IDL-files. In bounding_box it means all entities and in top_level_entities it should generate a BadParam exception. Would it not be better, to give it in both methods a similar meaning?

    Recommend "bounding_box" behavior.

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( …) - 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.

Several properties in the CadBrep::PropertyStruct need clarification.

    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.

CadFoundation::Entity interface

  • Key: CAD-31
  • Legacy Issue Number: 4570
  • Status: closed  
  • Source: Open Cascade ( Mikhail Kazakov)
  • 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 );

Method names in topological entities are not everywhere unified

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

    5. Method names in topological entities are not everywhere unified. To return a single entity we use normally prefix get_entity.
    To return a sequence we use no prefix normally: for example

    Shell get_shell () raises (CadUtility::CadError);
    OrientedFaceSeq oriented_faces () raises (CadUtility::CadError);

    Not all method names in CadBrep module satisfy this rule.

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

  • Key: CAD-25
  • Legacy Issue Number: 4560
  • Status: closed  
  • 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.

adding an attribute to the entity group

  • Key: CAD-22
  • Legacy Issue Number: 4551
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Our entity groups in Cad Services don't have any form of an
    identifier or name that can be retrieved through the interface.
    The only returned data is either a list of entities in the group or
    the count. It makes it difficult to present this information to a
    user.

    We might consider adding an attribute to the entity group,
    however that means it gets inherited to the layer.
