Overview 

This guide explains what a callout is and how to create and modify it in a drawing environment. 

You will learn how to: 

• Understand what a callout is 

• Create a callout from scratch 

• Modify an existing callout 

• Reverse, replace, and recreate callouts 

 

What is a Callout? 

A callout is a graphical element used to identify the cutting/projection plane and its orientation, of drawing views, such as: 

• Section views 

• Detail views 

• Projection views 

It typically consists of: 

• A profile (line, circle, or shape) 

• An arrow indicating direction 

• A label (e.g., A-A, B-B) 

⚠️ Important: 
Callouts are not standard geometry. 

• They cannot be moved like normal elements 

• They are linked to views and their definitions 

 

Creating a Callout 

To create a callout from scratch: 

1. Open a drawing document 

2. Select a view (main view) 

3. Choose one of the following tools depending on your need: 

• Section View 

• Detail View 

• Projection View 

4. Draw the callout profile: 

• For a section → draw a cutting line 

• For a detail → draw a circle or boundary 

• For projection → define projection direction 

5. Place the resulting view 

✔ The callout is automatically created and linked to the new view 

 

 

 

Modifying an Existing Callout Geometry 

1. Double-click the callout 
   → The Edit/Replace toolbar appears 

 

2. Drag elements of the callout (e.g., endpoints) 

3. (Optional) To constrain one segment, right-click this segment and select Line.object > Fix. 

4. Click End Profile Edition 

​​​​​​​                  

✔ The view updates automatically 

 

Inverting the Callout Direction 

1. Double-click the callout 

2. Click Invert Profile Direction 

  

3. Finish editing 

✔ The direction of the callout is reversed 

 

Note: 

• This feature is not available for detail views 

 

Replacing a Callout 

1. Double-click the callout 

2. Click Replace Profile  

 

3. Draw a new profile 

4. Double-click to finish 

✔ The old callout is replaced

1-Modification of Callouts 

If you modify a section or auxiliary callout in such a way that the resulting view becomes inconsistent with its original definition (for example, if the resulting view plane is no longer valid relative to the defining view): 

• All callouts of the resulting view are displayed in red 

• These callouts cannot be edited 

• The modification is not propagated to related detail views 

Important: 

Inverting a callout profile is allowed and does not always cause an issue. 

Callouts turn red only if the modification (including inversion) creates an inconsistency between the defining and resulting views. 

 

2. Translation of Section Callouts 

If you move (translate) a section callout 

• The plane of the resulting section view is modified 

• It remains parallel to its previous orientation 

However, this creates an inconsistency with dependent views. 

As a result: 

• The detail callout becomes red 

• Other callouts remain unchanged 

• All callouts are still editable 

⚠️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. 

Note: 

This situation is not resolved by updating the view. 

The red callout indicates a logical inconsistency between views rather than an update issue. 

 

3. Resizing of Callouts 

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

• The detail callout does not turn red 

• The callout remains valid and editable 

 

Summary 

Callouts are essential elements used to define relationships between views in a drawing. 
They are automatically created when generating views, but can also be modified, replaced, or recreated when needed. 

Understanding how they work ensures consistency and accuracy in technical drawings.
