How to Write VBA Scripts in CorelDRAW

Automating repetitive graphic design tasks in CorelDRAW can significantly boost productivity and eliminate human error. This guide provides a straightforward walkthrough on using Visual Basic for Applications (VBA) in CorelDRAW, covering how to access the developer environment, understand CorelDRAW's Document Object Model, write functional scripts for creating and manipulating shapes, and optimize macros for high-speed execution.

Accessing the VBA Environment

CorelDRAW includes a built-in Integrated Development Environment (IDE) for writing and debugging macros.

  1. Launch CorelDRAW and open a document.
  2. Press Alt + F11 on your keyboard, or navigate to Tools > Scripts > Script Editor (in older versions, Tools > Macros > Macro Editor).
  3. Open the Scripts Docker (or Macro Manager) via Tools > Scripts > Scripts (Alt + Shift + F11) to view, run, and manage existing projects.

In the Project Explorer pane on the left side of the VBA Editor, you will see GlobalMacros.gms (accessible across all documents) and your active document's macro storage. For scripts meant for repeated daily use, add them under GlobalMacros.

Understanding the CorelDRAW Object Model

To interact with CorelDRAW using code, you must navigate its object hierarchy. The core components include:

  • Application: The root object representing CorelDRAW itself.
  • ActiveDocument: The currently focused document.
  • ActivePage: The page currently displayed.
  • ActiveLayer: The layer where new objects are placed.
  • ActiveSelection / ActiveSelectionRange: The set of currently selected objects.
  • Shapes: The collection of vectors, text, or bitmaps on a layer or page.

Writing a Basic Automation Script

To create a new script:

  1. Right-click GlobalMacros in the Project Explorer, choose Insert, and select Module.
  2. Double-click the new module to open the code window.
  3. Define a subroutine using Sub and End Sub.

The following example creates a new rectangle on the active layer, fills it with red, and removes its outline:

Sub CreateRedRectangle()
    Dim sh As Shape
    
    ' Check if a document is open
    If Documents.Count = 0 Then
        MsgBox "Please open a document first.", vbExclamation
        Exit Sub
    End If
    
    ' Create a rectangle: Left, Top, Right, Bottom (coordinates in document units)
    Set sh = ActiveLayer.CreateRectangle(0, 5, 5, 0)
    
    ' Apply a uniform red fill
    sh.Fill.UniformColor.RGBAssign 255, 0, 0
    
    ' Remove the outline
    sh.Outline.SetNoOutline
End Sub

Batch Processing Selected Objects

A primary use case for VBA is batch modification of selected items, such as resizing, recoloring, or exporting multiple graphics at once.

The following script iterates through all selected shapes and sets their outline width to 1 millimeter:

Sub SetSelectionOutlineWidth()
    Dim sh As Shape
    Dim sel As ShapeRange
    
    Set sel = ActiveSelectionRange
    
    If sel.Count = 0 Then
        MsgBox "Please select at least one object.", vbInformation
        Exit Sub
    End If
    
    ' Loop through each shape in the current selection
    For Each sh In sel
        sh.Outline.Width = 1 ' Width value corresponds to document outline units
    Next sh
End Sub

Performance Optimization

When manipulating hundreds or thousands of shapes, the user interface will attempt to redraw after every single action, significantly slowing down execution. CorelDRAW provides properties to disable redraws and undo tracking while a macro runs.

Wrap resource-heavy routines with the following optimization commands:

Sub OptimizedBatchOperation()
    On Error GoTo ErrorHandler
    
    ' Disable screen updates and events for performance
    Optimization = True
    ActiveDocument.BeginCommandGroup "Batch Process"
    EventsEnabled = False
    
    ' --- Place automation logic here ---
    
ErrorHandler:
    ' Ensure document settings are restored even if an error occurs
    EventsEnabled = True
    ActiveDocument.EndCommandGroup
    Optimization = False
    ActiveWindow.Refresh
End Sub

BeginCommandGroup bundles the entire script execution into a single "Undo" step in the CorelDRAW history, preventing users from having to manually undo hundreds of automated actions individually.

Running and Assigning Shortcuts to Scripts

Once your code is written and saved:

  1. Open CorelDRAW and view the Scripts docker.
  2. Locate your subroutine under the appropriate module.
  3. Double-click the macro name to run it.
  4. To assign a shortcut key or toolbar button, navigate to Tools > Options > Customization, click Commands, filter by Macros, select your script, and assign a shortcut key or drag it directly onto an existing toolbar.
