Generate box geometry (solid, sheet, wire) Macro Feature using SOLIDWORKS API

This VBA example demonstrates how to create macro feature which generates custom geometry.

Open part document and run the macro. New feature is inserted in the Feature Manager tree and box geometry is generated either as solid, sheet or wire body.

Configuration

Embedding

Set the value of EMBED_MACRO_FEATURE constant to specify if macro feature should be embedded to file or not. If this option set to True then part document can be opened on any other computer and the geometry will be present without the need to copy the macro.

Box Size

Size of the box can be configured by changing the WIDTH, LENGTH and HEIGHT constants:

Const WIDTH As Double = 0.01
Const LENGTH As Double = 0.01
Const HEIGHT As Double = 0.01

Body Type

Generated body type can be set by assigning the value to BODY_TYPE constant

swBodyType_e.swSolidBody

Creates a box as a solid body geometry.

swBodyType_e.swSheetBody

Creates a single surface body by sewing the faces of the box.

Macro feature generates surface (sheet) body

swBodyType_e.swWireBody

Creates wire bodies from all edges of the box geometry. Wire bodies are edges and not presented in the bodies folders. Example of wire bodies used in standard feature tree are curves (composite, through XYZ, projected etc.)

Const BODY_TYPE As Integer = swBodyType_e.swSolidBody
Const EMBED_MACRO_FEATURE As Boolean = False
Const BASE_NAME As String = "Box"

Const WIDTH As Double = 0.01
Const LENGTH As Double = 0.01
Const HEIGHT As Double = 0.01
