Summary: Demonstrates how to create polar arrays of objects using RhinoScript.
I noticed that RhinoScript does not have any array methods. That is, methods that transform objects similar to Rhino's array command, such as ArrayPolar? Is there a way to lay out objects similar to this using RhinoScript?
Consider the following example script code. Note, this code assumes that objects will be rotated around the world z-axis. But, one could certainly modify it to rotate around a user-defined axis.
Option Explicit Sub MyArrayPolar Dim arrObjects, arrCenter, nCount Dim dAngle, arrAxis, arrXform, i arrObjects = Rhino.GetObjects("Select objects to array") If IsNull(arrObjects) Then Exit Sub arrCenter = Rhino.GetPoint("Center of polar array") If IsNull(arrCenter) Then Exit Sub nCount = Rhino.GetInteger("Number of items",,2) If IsNull(nCount) Then Exit Sub dAngle = 360.0 / nCount Rhino.EnableRedraw False For i = 1 To nCount - 1 arrAxis = Array(0,0,1) ' world z-axis arrXform = Rhino.XformRotation(dAngle * i, arrAxis, arrCenter) Rhino.TransformObjects arrObjects, arrXform, True Next Rhino.EnableRedraw True End Sub
