type mismatch in parameter. array required.

hi,

I'm relatively new to RhinoScript, and I'm stuck at this tiny script, that I can't seem to figure out why isn't working. It's probably basic stuff. It keeps giving me the "type mismatch in parameter. array required" - even though I'm convinced it is an array I'm feeding it.

Call Circles()
Sub Circles()

Dim i, j
Dim arrPoints
Dim dblRadi

dblRadi = 2.0

arrPoints = Rhino.GetPointCoordinates("Select points")
If IsNull(arrPoints) Then Exit Sub

For i = 0 To Ubound(arrPoints)
Call Rhino.Print("Point array (" & i & "): " & Pt2Str(arrPoints(i)))
Call Rhino.AddCircle(arrPoints(i), dblRadi)
Next

End Sub

thanks in advance,
oh, and - is there an official RhinoScript discussion forum? I can't seem to find it.

From Rhinoscript help:



AddCircle

Adds a circle curve to the document.



Syntax

Rhino.AddCircle (arrPlane, dblRadius)



Parameters

arrPlane

Required. Array. The plane on which the circle will lie. The origin of the plane will be the center point of the circle.



dblRadius

Required. Number. The radius of the circle.





Returns

String

The identifier of the new object if successful.



Null

If not successful, or on error.





Example

Dim arrPlane



arrPlane = Rhino.WorldXYPlane



Rhino.AddCircle arrPlane, 5.0

The AddCircle function takes a cplane as its first argument, though, you are feeding it a point...that is not enough.

You need to do something like this:







Call Circles()



Sub Circles()



Dim i, j

Dim arrPoints

Dim dblRadi

Dim strCir



dblRadi = 2.0



arrPoints = Rhino.GetPointCoordinates("Select points")



Call Print(UBOUND(arrPoints))

If IsNull(arrPoints) Then Exit Sub



For i = 0 To Ubound(arrPoints)

Call Rhino.Print("Point array (" & i & "): " & Pt2Str(arrPoints(i)))

strCir = Rhino.AddCircle(Rhino.WorldXYPlane, dblRadi)

Call Rhino.MoveObject(strCir,array(0,0,0), arrPoints(i))



Next



End Sub

And no, there is no forum like this one here for Rhinoscript only. There are diverse locales around the web, but nothing that organizes things like this. So either we mke another NING group for this, or the powers that be add a section to these forums for Rhinoscript...

Rhinoscript seems that its poised to change a bit in Rhino 5 as different capabilities get integrated. Surely a place like this for Rhinoscript users ... even a general coding group, for SDK programmers, Rhinoscript peeps, etc can gather. Currently, the Rhino.Plugins Newsgroup handles it all.

The best place to get Rhinoscript help is the Rhino Plugins Newsgroup. A number of plugin developers along with scripters and the guys from McNeel are there so you can get pretty good answer pretty quick.

There's also Rhinoscript.org which would be a good place. They have a forum. It seams fairly active, although I've never really spent much time there.

thanks for the input,
i know about rhinoscript.org, but it's been a while since i stopped by. i actually thought it was more or less dead, but i see now that it still kicks.

cheers.
