    message-to-show-when-empty-or-no-value-given

    • Then we stop our macro here.
' This will handle case for Non-numeric values
If IsNumeric(response) = False Then  
  MsgBox "Entered value is Non-numeric. Please try again."  
  ' Clear all selection
  swDoc.ClearSelection2 True
  Exit Sub
End If
  • In above code block, we check if the input value is Non-numeric.
  • This check will handle case for Non-numeric values.
  • We use πŸš€ IF statement for checking.
  • Condition: IsNumeric(response) = False
    • IsNumeric() is pre-build VBA function which check if passing object is Numeric or not.

    entering-non-numeric-value

    • In above cases, we will get False value.
  • When this condition is True,
    • We show and πŸš€ message window to user.
    • Message: Entered value is Non-numeric. Please try again.

    message-to-show-non-numeric-value-given

    • Then we stop our macro here.
' Variable for Wrap thickness
Dim wrapThickness As Double
  • In above line, we create a variable to store Wrap thickness.
  • Variable Name: wrapThickness
  • Type: Double
wrapThickness = CDbl(response) * LengthConversionFactor
  • In above line of code we are doing 3 steps in one line.

    Those 3 steps are explained below.

    • Step 1 - Converting Wrap thickness from user to Double type.
    • Step 2 - Updating converted Wrap thickness as per document unit system.

    • Step 3 - Assigned input value to wrapThickness variable.
' This will handle case for 0 Wrap thickness
If wrapThickness = 0 Then
  MsgBox "Entered value must be greater than 0. Please try again."
  ' Clear all selection
  swDoc.ClearSelection2 True
  Exit Sub
End If
  • In above code block, we check if the input value is zero (0).
  • This check will handle case for 0 Wrap thickness.
  • We use πŸš€ IF statement for checking.
  • Condition: wrapThickness = 0

entering-zera-as-value

  • When this condition is True,
    • We show and πŸš€ message window to user.
    • Message: Entered value must be greater than 0. Please try again.

    • Then we stop our macro here.

Create Wrap feature

In this section, we create Wrap feature.

' Variable for Solidworks Wrap Feature
Dim swFeature As SldWorks.Feature
  • Purpose: In above line, we create a variable for Solidworks Wrap Feature.
  • Variable Name: swFeature
  • Type: SldWorks.Feature
  • Reference: Please visit πŸš€ online SOLIDWORKS API Help.
' Create Wrap feature
Set swFeature = swDoc.FeatureManager.InsertWrapFeature2(swWrapSketchType_e.swWrapSketchType_Engrave, wrapThickness, False, 0, 1)
  • In above line, we set the value of variable swFeature by InsertWrapFeature2 method.

  • This InsertWrapFeature2 method takes following parameters as explained:

    • Type - Type of wrap as defined in swWrapSketchType_e:

      Member Description
      swWrapSketchType_Emboss 0 = Emboss creates a raised feature on the selected face or faces
      swWrapSketchType_Engrave 1 = Engrave, which appears as Deboss in the user interface, creates an indented feature on the selected face or faces
      swWrapSketchType_Scribe 2 = Scribe creates an imprint of the sketch contours on the selected face or faces
    • Thickness - Thickness; 0.00001 (thinnest) - 10000 (thickest).

    • ReverseDir - True to reverse the direction of the wrap, False to not

    • Method - Type of wrap method as defined in swWrapMethods_e:

      Member Description
      swWrapMethods_Analytical 0
      swWrapMethods_SplineSurface 1
    • MeshFactor - Accuracy of flattened triangle mesh; 1 (lowest) - 10 (highest).

  • Return Value : This InsertWrapFeature2 method return πŸ‘‰ Feature data object.

  • In our code, I have used following values:

    Parameter Name Value Used
    Type swWrapSketchType_Engrave
    Thickness wrapThickness
    ReverseDir False
    Method 0
    MeshFactor 1

Reference: For more details about

' Check if Wrap feature creates or not
If swFeature Is Nothing Then
  MsgBox ("Failed to create Wrap feature.")
  ' Clear all selection
  swDoc.ClearSelection2 True
  Exit Sub
End If
  • In above code block, we check if we successfully create *WrapFeature or not.
  • We use πŸš€ IF statement for checking.
  • Condition: swFeature Is Nothing
  • When this condition is True,
    • We show and πŸš€ message window to user.
    • Message: Failed to create Draft Feature.
    • Then we clear all selection and stop our macro here.

Now we run the macro and after running macro we get Wrap feature as shown in below image.

wrap-feature-final-result

Final work

In this section, after creating Wrap Feature, we have to do some cleaning work so that we can use this macro frequently.

' Erase array data
Erase swObjects
  • In above line, we erase data from SOLIDWORKS Entity array.
  • For this we use Erase function in-build in VBA.
' View zoom to fit
swDoc.ViewZoomtofit2
  • In above line, we make our view zoom to fit the model.
  • For this we use ViewZoomtofit2 method which is part of SOLIDWORKS Document variable i.e swDoc variable.
' Clear all selection
swDoc.ClearSelection2 True
  • In above line, we clear all previous selection.
  • For this we use ClearSelection2 method which is part of SOLIDWORKS Document variable i.e swDoc variable.
