You are required to input following dimensions:

In the Position list, select Connect or Unchanged:

• Click Connect (default when Create is selected) - connects the piece of HVAC to the previous one.

• Click Unchanged (default when Modify is selected) - positions the component at the co-ordinates 0.00.

  Note:
  Unchanged is usually used, when Modify is selected, it does not connect the component but positions it at 0.00, in effect in a floating position.

Click Defaults to reset all the fields back to when the Mitred Elbow window was opened.
