Import Into Storage World

To import into an Application Data World (APPDWL) hierarchy:

1. Set the Import Location radio button to Import into storage world. If the project contains existing storage worlds, these will be displayed in the Select Storage World pane.

   

2. Clicking on a storage world shows its hierarchy in the tree below. If the user has write access to a storage world in the list, it can be modified by clicking on the storage world and using the tasks beneath.

3. Clicking the right mouse button on elements in the tree displays functions that can be performed at that element.

   

4. Clicking Create New World creates a new model import storage world (an APPLDW element with purpose attribute = MIMP), an Application Data Area (APPDAR) and Application Data Group (APPLDA) which is the basic structure needed to import into.

   

5. To modify the model import storage world's attributes, select from the Select Storage World list and click Modify World Attributes.

   

   Note: If the storage world is new the Modify Attributes fields will be blank.

6. The user can change the values in the fields and click on Apply to store the new values in the database. The new values are displayed in the Select Storage World list. Click Back to cancel the changes and return to the original window.

7. To delete a storage world and all the imported models in that world, select the storage world from the Select Storage World list and click Delete World. A confirmation window is displayed requesting the user to confirm the deletion.

   

8. Select Yes to confirm the deletion or No to cancel the deletion and return to the Mechanical Equipment Interface window.

9. Clicking Modify Hierarchy displays a list of tasks to modify the hierarchy of the storage world.

   

   Create Model Import Area	Creates a new model import area (an APPDAR element).
   Create Model Import Group	Creates a new model import group (an APPLDA element owned by the selected APPDAR element)
   Modify Attributes	Shows input fields to modify attributes of the selected element.
   Delete Item	Delete the selected item and any items that it owns.

   Tasks in the list are active depending on what is selected in the tree. To return to the Import file panel, press the Back button.

10. To select the file to be imported click Browse to display a file browser which allows the user to navigate to and select a .stp file. The selected file will be displayed in the Import File field.

    

11. Once the location where the file is to be imported is highlighted in the tree and Import File field have been populated, the Import button becomes active.

    Note: If either the location or the Import File field are blank the Import button will be greyed out and inactive.

    

12. The user can choose how the model data is imported by selecting Equipment (EQUI), Volume Model (VOLM) or Sub-equipment (SUBE) from the Import model as drop-down menu.

13. When the model data contains assemblies and is imported as Equipment the user can choose to create a Sub-equipment level beneath the Equipment element by checking Create SUBE level.

14. When re-importing the same model into the same area, the user has the option to save any existing nozzles in that area by checking the Save existing nozzles on import box. If the Save existing nozzles on import box is not checked, then any nozzles that exist will be deleted.A warning message will be displayed to confirm this.

15. If the Enable tessellation cache checkbox is checked a faceted approximation of the model is created with the given tolerance during the import and stored with the model. The used tolerance should be in the interval 0.1mm and 20.0mm, default value is the arc tolerance. When a different tolerance is requested and the approximation is no longer valid a faceted model with the new tolerance will be created that replaces the stored one.

    If the STEP AP203 file-name 100% matches a piece of existing equipment in the model, a collection of type 'NOZZ' and 'SUBE' is run on the existing piece of equipment. These collections are used to build an appropriate message which is returned to the user for the appropriate action taken on the existing piece of equipment. This includes:

    • Overwriting an existing piece of equipment.

      

    • Overwriting an existing piece of equipment saving existing nozzles.

      

    • Overwriting an existing piece of equipment importing into a new sub-equipment.

      

    • Overwriting an existing piece of equipment importing into a new sub-equipment and saving existing nozzles.

      

      (If no nozzles exist and the toggle is checked, this is returned to the user on import.).

    • All primitive based elements which are owned by an existing piece of equipment are deleted on import.

      

      If the user does not wish to overwrite an existing piece of equipment and selects No from the confirmation message then a new confirmation message is shown asking the user if they want to import the data into a new piece of equipment, a new EQUI is created and the imported model is created beneath. This new piece of equipment will be assigned a name as follows: STEP AP203 file + "-MEI-IMPORT".

      If the user repeats this operation the naming index is 1 to 1000.

      

      

16. Click Import to begin the import process.

    Note: The importing operation can take a long time if the models are particularly large and complex.
