Polylines
Polylines
(OP)
Hello,
I'm runngin AutoCAD 2006 and have built an application with VBA. I've got the following code in my application in an attempt to create a six sided shape programmatically:
Private Sub cmdTest_Click()
Dim Points(5) As Double
Dim PLine As AcadLWPolyline
Dim SelectionSet As AcadSelectionSet
Points(0) = 20: Points(1) = 20: Points(2) = 20
Points(3) = 20: Points(4) = 20
Set AcadPolyline = ThisDrawing.ModelSpace.AddLightWeightPolyline(Points)
ZoomAll
End Sub
All I get is a straight line. What am I missing here? Any help is greatly appreciated.

RE: Polylines
Your points array is wrong. What you need is a 3 point array point for each vertex of the polyline.
For example the code below is for a rectangular polyline.
With any coordinate entry, VB requires at least 2 points in the array for each end point or start point etc - Point(0) refers to the X coordinate, Point(1) refers to the Y coordinate and Point(2) refers to the Z coordinate of each point and then Point(3) will refer to the X of the next point and so on. So make sure you point array is in multiples of either 2 or 3, so for a rectangle, you'll need an array of 12 in total - which is 0 to 11). 5 as you have will confuse the program..
CODE
Points(0) = 0: Points(1) = 0: Points(2) = 0 'Start point..
Points(3) = 20: Points(4) = 0: Points(5) = 0 '2nd point..
Points(6) = 20: Points(7) = 20: Points(8) = 0 '3rd point..
Points(9) = 0: Points(10) = 0: Points(11) = 0 'End point..
Set PLine = ThisDrawing.ModelSpace.AddLightWeightPolyline(Points)
Pline.Closed = True
ZoomAll
Some may debate whether you need the final point again, if you're going to Closed = True the polyline..
Also, note your line that creates the polyline itself, you need to set the variable name as the object not the object itself..
I hope i explained it ok, give me a shout if you need any more info..
