About Location Callouts
You can define a zone or location grid to drawing formats by creating location callouts. You define the location grid by using the existing lines of a format or by using equally spaced increments. Use this location grid to locate drawing views using parametric notes to indicate both the sheet and drawing location of a view.
Parametric location callouts allow for intelligent notes to be added to drawings to indicate the location of a detail or section view, saving time and preventing out-of-date notes.
Location callouts are created using a standard syntax:
• View location—&pos_loc:view:<view name>
• Sheet of view—&sheet:view:<view name>
• Note location in parent view—&pos_loc:parent_note:<view name>
• Sheet location of note—&sheet:parent_note:<view name>
For example, if Detail A is located in A3 on the location callout grid and on sheet 2, type the note:
See Detail A at &pos_loc:view:detail_a on sheet &sheet:view:detail_a
The note text shows as:
See Detail A at A3 on sheet 2.
The syntax for the location callouts is customizable, which allows for additional text to be added based on individual company standards. The Detail option pos_loc_format is provided to specify the syntax of the pos_loc and sheet parameters in the callout. The default of pos_loc_format is %s%x%y, and appears as 2D4.
%r added to pos_loc_format will repeat the syntax string for the same item appearing several times in different locations. This applies to items such as symbols and connectors, but not to views because views have unique names. The syntax will be %s%x%y, %r where %r means to repeat the substring from the first special character to the last.
&pos_loc
Behavior:
The location note updates upon regeneration if the view is moved on the drawing. If the view is erased or moved outside of the grid, the value of the location callout changes to ***. The callout updates when the view is resumed or the view is moved back onto the grid. If the view is deleted, then the location callout is no longer parametric and the value changes to ***.
&sheet
Behavior:
If you switch the view to a different sheet, the location callout automatically updates to the new sheet number. If the view is erased, the value of the location callout changes to ***. The callout updates when the view is resumed. If the view is moved outside of the grid, the value remains as the correct sheet number. If the view is deleted, then the location callout is no longer parametric and the value changes to ***.
You specify which corner of the location grid you want as the origin. The grid origin is shown as a yellow X. The default grid origin is the lower right corner of the location grid.
