SOLIDWORKS allows to insert the free form curve through XYZ coordinates from the external text file. This file however is not linked to the feature itself and the curve is not updated when external file changes.
This VBA macro allow to automatically link the external file with coordinates and update the selected curve with single click.
Example of curve file:
0mm 0mm 0mm
10mm 10mm 10mm
5mm 1mm 25mm
Curve text file must be saved in the same folder where the SOLIDWORKS file is saved and must be named as [Model Title]_[Feature Name].sldcrv. For example if curve feature is named Curve1 and resides in the SOLIDWORKS file named Part1.sldprt, the curve text file must be named Part1_Curve1.sldcrv.
Dim swApp As SldWorks.SldWorks
Sub main()
Set swApp = Application.SldWorks
Dim swModel As SldWorks.ModelDoc2
Set swModel = swApp.ActiveDoc
If Not swModel Is Nothing Then
Dim swFeat As SldWorks.Feature
Set swFeat = swModel.SelectionManager.GetSelectedObject6(1, -1)
If Not swFeat Is Nothing Then
Dim swCurveFeatDef As SldWorks.FreePointCurveFeatureData
Set swCurveFeatDef = swFeat.GetDefinition
If Not swCurveFeatDef Is Nothing Then
Dim filePath As String
filePath = swModel.GetPathName
filePath = Left(filePath, InStrRev(filePath, ".") - 1)
filePath = filePath & "_" & swFeat.Name & ".sldcrv"
If False = swCurveFeatDef.LoadPointsFromFile(filePath) Then
MsgBox "Failed to update curve"
End If
swFeat.ModifyDefinition swCurveFeatDef, swModel, Nothing
Else
MsgBox "Selected feature is not XYZ points curve"
End If
Else
MsgBox "Please select Curve XYZ feature"
End If
Else
MsgBox "Please open model"
End If
