How To Create References In Pro/Engineer WF5.0

About References

To dimension and constrain geometry, Pro/ENGINEER requires you to create references. References can be created through the References dialog box. To open the References dialog box, click Sketch ? References.

Pro/ENGINEER prompts you to create references in the following situations:

 ?  When you create a new feature, the References dialog box opens. Pro/ENGINEER prompts you to select a perpendicular surface, edge, intent edge vertex, datum reference or composite curve relative to which the section will be dimensioned and constrained.
 ?  When you redefine a feature that has missing references.
 ?  When you do not have enough references to place a section.

Note:

When you create a new feature, the Pro/ENGINEER automatically selects default Sketcher references. You can change these references or create new ones in the References dialog box.

When working with a section, if the sketch reference becomes invalid or is removed, you can update or remove the failed or missing reference. Additionally, you can replace the failed or missing reference with an alternative reference.

You can delete, update, or replace a failed reference, even if the reference belongs to an external model.

You can use the Undo or Redo commands when resolving failed or missing reference.

When you delete, update, or replace a reference using the References dialog box, the sketch is not updated automatically and you can choose to update the sketch.

Note

The sketch is updated automatically if you replace a reference using the Edit ? Replace command.
The Solve option in the Reference dialog box is available only if there are no failed or missing references.

To Create References

 1. Click Sketch ? References. Pro/ENGINEER displays the References dialog box.
 2. Select from the following options:
 ?  Select—Use this tool to create references for dimensioning and constraining. Click on model geometry to create a reference. Pro/ENGINEER displays each new reference in the References list.
 ?  X sec—Use this tool to create references at the intersection of a sketching plane and a surface or an intent surface. To create a reference, click at the intersection of a sketching plane and a surface. Pro/ENGINEER displays each new reference in the References list.
 ?  Delete—Use this option to delete references. Select the reference you wish to delete from the references list. Click Delete. Pro/ENGINEER deletes the selected reference.
 ?  Chain—Use this list filter to select all edge references in the References dialog box.
 ?  Solve—Use this option to solve the sketch. This option is available only if there are no missing or failed references.

Note
 ?  To delete all edge references, click Chain and click Delete.
 ?  When selecting from the reference list you can highlight multiple references by holding down the CTRL key as you select.
 
 3. Click Close. Pro/ENGINEER accepts the references and closes the dialog box.

Note:
You can sketch without creating sufficient references as long as you create the required references later.
