[Secondary Development of SolidWorks] Feature Modeling -- stretching (1)

First, record a macro that generates the stretching feature and analyze the VBA code.

Recording macro:

1. Call the macro recording function;

 

2. Insert stretching features

2.1 draw a sketch

 

2.2 complete feature Creation

 

3. Tensile features are obtained.

37 Part. SelectionManager. enabledeletion selection = 0
38 End Sub

Code Analysis:

The FeatureExtrusion2 method of the FeatureManager class is used to generate tensile features. Of course, before generating features, we need to use the SelectByID2 method to select the contour to be stretched (that is, the sketch ).
