Modifying a Callout Geometry  

This task will show you how to modify the geometrical characteristics of a callout used when creating detail views, section views and section cuts. You will learn about: 
Callouts represent an operation that has been performed on a generative view (such as a section cut for example) and consequently do not behave as geometry. As a result, you cannot isolate callouts, nor can you apply transformation or symmetry operations to callouts.
Open the GenDrafting_part_Callout.CATDrawing document.

Modifying the Existing Callout Geometry

  1. Double-click the callout to be modified.

    The Edit/Replace toolbar appears.

  2. Drag one of the element components to the desired location. In this particular case, drag one segment extremity of the callout.

    • By default the  segment extremities are not fixed.

    • To constrain one segment, right-click this segment and select Line.object > Fix.

    • To free one segment, right-click this segment and select Line.object > Unfix.

  3. Click End Profile Edition in the Edit/Replace toolbar.

    The callout arrow is now properly positioned and the section view (B-B) is automatically updated.



Reversing the Callout Direction

  1. Double-click the callout to be reversed.

    The Edit/Replace toolbar appears.

  2. Click Invert Profile Direction in this toolbar.

    The callout is automatically inverted.

    • At any time, you can stop editing the callout by clicking End Profile Edition in the Edit/Replace toolbar.
    • You cannot reverse the callout of a detail.
    • If the modification of a view containing a callout makes the projection planes of the defining and the resulting views inconsistent, the callout turns red to show that there is an inconsistency in the drawing. For more information, refer to More about red callouts below.

Replacing the Callout

  1. The callout to be replaced.

    The Edit/Replace toolbar appears.

  2. Click Replace Profile in this toolbar.

  3. Start creating the new profile.

  4. Double-click to end the new profile creation.

    The new profile automatically appears and the old one disappears.

Recreating the Callout

Callouts may be recreated in one of the following conditions:

  1. Callout has been manually deleted.

  2. View containing the callout has been deleted.

  3. View cut/pasted in another drawing.

  4. View containing the callout has been modified and callout became invalid (“red” callout).

The following types of callouts can be recreated:

  • section callouts

  • detail callouts

  • projection callouts 

The recreated callout type (section, detail or projection) is given by the resulting view definition and is not defined or specified by you.

If the resulting view is... and projection planes of resulting and new defining views are... So the recreated callout is...
an Auxiliary view

perpendicular a projection callout
a Section view

perpendicular a section callout
a Detail view

parallel a detail callout
Detailed section view (*)

parallel a detail callout

* In this case the defining and resulting view section profiles have to be equal.

To recreate a callout:

  1. Right click the view to display the contextual menu and select Detail X object > Add Callout.
    This menu is available through Edit > Detail A object > Add Callout.
    In this case you can see that the callout for Detail view A, has been deleted. Activate the detail view and follow the procedure given.

    • If the resulting view already has a valid callout in the defining view then the following error message will be displayed.
    • If the resulting view has a invalid callout (red in display) then the following warning message is displayed, but command continues to the next step.
  2. Click on the main defining view where we have to recreate the callout. The callout is recreated and the red callout is removed.

    In this case you can see that callout for Detail A has been recreated.

To recreate the callout the following conditions have to be satisfied:
  • From a view that has been deleted, it is necessary that the new defining view exists or may be created with the same characteristics as the previous defining view.

  • Projection plane of each view has to be parallel in case of detail callout and perpendicular in case of projection and section callout.

  • 3D origin and orientation of the view projection plane have to be equal.

  • Views haves to be linked to the same product/part.

  • View’s section profile have to be equal in case of detail callout re-creation.

  • Multiple callouts cannot be recreated from single defining view.
Callouts may be re-created in an aligned section view even if some inconsistency may appear in the drawing.

More About Red Callouts


Modification of Callouts

If you modify an auxiliary or a section callout in a way that the plane of the resulting view is not parallel anymore compared to the previous plane view or if you invert the profile:

  • all the callouts of the resulting view are displayed in red,
  • you cannot edit them,
  • the change is not propagated to detail view.

Translation of Section Callouts

If you translate a section callout, the plane of the resulting section view is modified. It remains parallel to its previous orientation, yet there is an inconsistency between the section view and the detail view defined on the previous plane view.
As a consequence:

  • the detail callout becomes red,
  • other callouts remain unchanged,
  • all callouts can be edited.
If you create a detail view on the section view and translate the section callout without any visible impact on the resulting section view, the detail callout becomes red anyway and is editable.

Resizing of Callouts

If you resize a section callout constrained by the supporting lines of the profile:

  • any detail callout does not turn into red,
  • it can be edited
