How to have Excel driven 3D sketch points?

Hi All,

I would like to use SWX to demo the results of an Excel calculation. How do I tie the cell value of the spreadsheet to the coordinates of

3D sketch points? If it works out, then the points will constrain a sketched circle through them. I am hoping to see the circle rotate in 3D in SWX.

It is times like this, I realize how limited the help file is.

Thank you all,

Why don't you use animator or equations to rotate the circle in an assembly. Sorry I don't know much about tying the cells to SW points thought.

Thanks for the pointer. I am glad to know it is possible. I now have a rough idea of what I need to do, but I am having trouble figuring out what I should use to represent the X, Y, Z coordinates in the equation editor. I know the points are refered to as Point1@PtsOnDish and so on, but what does swx call the coordinates of the points? Are these info covered somewhere?

I'm not sure about Excel driven, but I have a copy of a macro that drives point location froms a text file (that you could create from an Excel file if you want). Maybe it will help. Ken

----------------------------------------------------------------------- These will be your X, Y, and Z points respectively. Save this section (including the "-END-") as: C:/temp/pointcloud.txt.

1.25 1.125 .6325 0 1 0 2 3 5 8 3 4 7 3 9 4 2 9



Here's the macro:

' *** ' by Jim Sculley, edited by Matt Lombard ' requires a text file with xyz data at the hard coded location below ' *** Dim swApp As Object Dim currentDoc As Object Const fileName = "C:/temp/pointcloud.txt" Const swDocPART = 1 Const swDocASSEMBLY = 2 Dim nextLine As String Dim xVal, yVal, zVal As Double Dim point As Object

Sub main() Const errorString = "You must have a part file open to use this feature." Set swApp = CreateObject("SldWorks.Application") Set currentDoc = swApp.ActiveDoc If currentDoc Is Nothing Then swApp.SendMsgToUser (errorString) End End If If (currentDoc.getType = swDocASSEMBLY) Then swApp.SendMsgToUser (errorString) End End If If (currentDoc.getType = swDocPART) Then currentDoc.Insert3DSketch

Open fileName For Input As #1 ' Open file. Line Input #1, nextLine 'Read line into variable. nextLine = VBA.Trim(nextLine) Do While Not (nextLine = "-END-") ' Loop until -END- is found. xVal = Val(nextLine) 'convert string to number Line Input #1, nextLine yVal = Val(nextLine) 'convert string to number Line Input #1, nextLine zVal = Val(nextLine) 'convert string to number Set point = currentDoc.CreatePoint2(xVal * 0.0254, yVal *

0.0254, zVal * 0.0254) Line Input #1, nextLine Loop Close #1 ' Close file. Else 'must be a drawing swApp.SendMsgToUser (errorString) End If End Sub
