SOLIDWORKS API provides a low level access to geometry generation and processing via IModeler interface.
This interface allows to manipulate the geometry on a kernel level:
- Create surfaces from boundary representation (BREP) data
- Create curves
- Trim curves and surfaces
Geometry API is most commonly used to generate and modify bodies in Macro Features.
This section contains examples of working with geometry (adding, editing) using SOLIDWORKS API.
Previewing Temp Geometry
Temporary geometry is invisible and resides in memory. However it can be very useful to preview the geometry to troubleshoot. Below are code snippets allowing to preview different types of temp geometry
Curves can be previewed by converting them into the temp wire bodies which can be displayed in the graphics area.
PreviewCurves swModel, swCurve1, swCurve2, swCurve3 ... Sub PreviewCurves(model As SldWorks.ModelDoc2, ParamArray curves() As Variant) Dim i As Integer Dim swPreviewBody() As SldWorks.Body2 If Not IsEmpty(curves) Then ReDim swPreviewBody(UBound(curves)) For i = 0 To UBound(curves) Dim swCurve As SldWorks.Curve Set swCurve = curves(i) Set swPreviewBody(i) = swCurve.CreateWireBody() swPreviewBody(i).Display3 model, RGB(255, 255, 0), swTempBodySelectOptions_e.swTempBodySelectOptionNone Next End If Stop If Not IsEmpty(curves) Then For i = 0 To UBound(curves) Set swPreviewBody(i) = Nothing Next End If End Sub
