    Thank you so much for that! Solved my head-scratching problem too. Trying to forget everything I know about C and get my head around VB... :/

    Thanks, I finally figured that out this morning.

    both methods do work. The error is simply that you dimension arrVertices with size 8 (which means 0-8 including 8) and you assign only 0-7, so arrVertices(8) is undefined.

    I'm fairly experienced with programming, but not with VBScript. I am trying to write a simple script to import meshes from a file listing vertices and faces.

    When I use the script example for addmesh, it works fine. When I change from assiging array elements one by one to doing it in a loop, I get an error saying "Type Mismatch in parameters. Array Required". I tried "vartype" in both cases and get 8204 as a result for both, so I'm not sure what the issue is. I must use a loop to assign array elements since I plan to read in a file.

    Code example below: If I assign elements of ArrVertices like show below, I get the error. If I assign arrVertices elements one by one like arrFaceVertices, then I get no error.

    Dim index
    Dim arrVertices(8)
    index = 0
    While index < 8
    arrVertices(index) = Array(0.0, 0.0, 0.0)

    Dim arrFaceVertices(7)
    arrFaceVertices(0) = Array(0,1,4,4)
    arrFaceVertices(1) = Array(2,4,1,1)
    arrFaceVertices(2) = Array(0,4,3,3)
    arrFaceVertices(3) = Array(2,5,4,4)
    arrFaceVertices(4) = Array(3,4,6,6)
    arrFaceVertices(5) = Array(5,8,4,4)
    arrFaceVertices(6) = Array(6,4,7,7)
    arrFaceVertices(7) = Array(8,7,4,4)
    Rhino.AddMesh arrVertices, arrFaceVertices

    I'd greatly appreciate some help. Thanks.


Why are these buttons gray?
