Design Points

To provide convenient reference points for the relative positioning of items which make up the Design Template, a Design Point can be created at any required location.

Each Design Point, like a p-point, is positioned and orientated.Functionality is available to position and orientate design points dynamically.

To create, modify, or delete a Design Point, make sure the correct TMAR element is highlighted in the Template Browser.

On the Design Templates tab, in the Tools group, click Design Points to display the Design Points window.

The Design Points window allows the User to create, modify, and delete a Design Point.

The name of the currently selected Design Template and a list of defined Design Points display within the Design Points window.

Select the Navigate to Design Point check box to navigate to the selected Design Point in the 3D view.

Create Cartesian Design Point

A Cartesian Design Point (DPCA), owned by a Design Pointset (DPSE), is specified in terms of its coordinates only.

On the Design Points window, click Create > Cartesian Point to display the Create - Cartesian Design Point window.

Click OK to create the Design Point or Cancel to discard any inputs and close the Create - Cartesian Design Point window. The User is returned to the Design Points window.

Point Connection

The Point Connection window allows the User to define a connection type for the Design Point.

On the Create - Cartesian Design Point window, select Connection to display the Point Connection window.

Click OK to apply the connection definitions or Cancel to discard any inputs and close the Point Connection window. The User is returned to the Create - Cartesian Design Point window.

Create Cylindrical Design Point

A Cylindrical Design Point (DPCY), owned by a Design Pointset (DPSE), is specified as a position on the surface of a cylinder at a given position and with given dimensions.

On the Design Points window, click Create > Cylindrical Point to display the Create - Cylindrical Design Point window.

Click OK to create the Design Point or Cancel to discard any inputs and close the Create - Cylindrical Design Point Design Point window. The User is returned to the Design Points window.

Create Spherical Design Point

A Spherical Design Point (DPSP), owned by a Design Pointset (DPSE), is specified as a position on the surface of a sphere at a given position and with given dimensions.

On the Design Points window, click Create > Spherical Point to display the Create - Spherical Design Point window.

Click OK to create the Design Point or Cancel to discard any inputs and close the Create - Cylindrical Design Point window. The User is returned to the Design Points window.

Modify Design Point

The Design Points window allows the User to modify the currently selected Design Point in the list of defined Design Points. The Design Templates application identifies the design point type by default and displays either the Modify - Cartesian Design Point window, Create - Cylindrical Design Point window or Create - Spherical Design Point window.

Modify Cartesian Design Point

To modify the currently selected Cartesian Design Point, on the Design Points window, select Modify > Point to display the Modify - Cartesian Design Point window.

The functionality of the Modify - Cartesian Design Point is identical to that described in Create Cartesian Design Point.

Modify Cylindrical Design Point

To modify the currently selected Cylindrical Design Point, on the Design Points window, select Modify > Point to display the Modify - Cylindrical Design Point window.

The functionality of the Modify - Cylindrical Design Point is identical to that described in Create Cylindrical Design Point.

Modify Spherical Design Point

To modify the currently selected Spherical Design Point, on the Design Points window, select Modify > Point to display the Modify - Spherical Design Point window.

The functionality of the Modify - Spherical Design Point is identical to that described in Create Spherical Design Point.

Delete Design Point

The Design Points window allows the User to delete the currently selected Design Point from the list of defined Design Points. Alternatively the User can delete all Design Points for the currently selected Design Template.

Delete Point Set

To delete all Design Points from the currently selected Design Template, on the Design Points window, select Delete Point Set to display the Confirm window.

Click Yes to delete all Design Points from the currently selected template or Cancel to discard the Confirm window. The DPSE element is deleted from the Model Explorer.

Delete Point

To delete the currently selected Design Point in the list of defined Design Points, on the Design Points window, select Delete Point to display the Confirm window.

Click Yes to delete currently selected Design Point or Cancel to discard the Confirm window.

Dynamic Design Points

Positions and orientates design points dynamically.

In this example, a cylindrical design point is used to position and orientate a nozzle.

To create dynamic design points, design parameters data definitions must be created. Refer to Property Definitions for further information on the Define Template Properties window.

To position and orientate the nozzle at the design point, the NOZZ requires two rules. Refer to Parameters for further information on the Template Parameters window.

The required rules are:

• Position

  • DPPS 1 of TMPLATE

  • DPPS is a pseudo attribute which returns the position of the design point based on the HEIG, RADI and ANGL attributes of the DPCY

• Orientation

  • X IS DPDI 1 of TMPLATE

  • DPDI is a pseudo attribute which returns the direction of the design point based on the ANGL attribute of the DPCY.

    Note:
    The orientation rule can differ depending upon how the NOZZ Catalogue item is setup in the catalogue.

The attributes of the DPCY are set by the Template Parameters window, but they can also have rules allocated to them to make the position and orientation of the NOZZ dynamic.

The position and orientation of the design point can be desigposn parameter driven by adding rules to the DPCY:

• Orientation

  • Y IS U AND Z IS W (LDPR ANGL OF TMPLATE) S

    Note:
    The orientation rule can differ depending upon how the NOZZ Catalogue item is setup in the catalogue.

• Angle

  • LDPR ANGL OF TMPLATE

  • This modifies the ANGL attribute of the DPCY.

• Radius

  • 100mm + LDPR RADI OF TMPLATE

  • This modifies the RADI attribute of the DPCY.

    Note:
    The 100mm is a stand out and could also be another design parameter.

In addition, in this example, there is a simple diameter rule for the cylinder.

Therefore, by setting the design parameters, the NOZZ can be positioned and orientated around the equipment.

Default settings ANGL 45, RADI 1000mm.

Note:
The DPCY must display above the NOZZ in the hierarchy so that the DPCY Position and orientation rules are run before the NOZZ rules, as the NOZZ is positioned and orientated based on the DPCY.
