Roger, Thanks for the quick reply. This functionality is fundamental to the project I was hoping to implement - nesting of solids. Do you have an ETA of when these functionalities will be exposed in .net? I really can't justify learing C++ for this project. Unigraphics has a similar problem when they went from C++ based API to the .NET system. They addressed it by wrapped the C++ functions as vb.net. Do you have any plans to possibly do this? Thanks again for your help. Roger James

Hi guys, Newbie NetHook programmer here. NetHook2_0.dll X2_MR2 I have the following code to add a solid to an operation I've imported. However, I can't find the docs or an example that tell me how to access / manipulate the Surface Rough Contour. All I can find seems to talk about 2D ops. code: Public Overrides Function Run(ByVal param As Integer) As MCamReturn Dim strOpsFile As String = "J:MasterCamTestTemporaryOpsFile.mcx" Dim intOpID As Integer = 2 '-> place all solids into an array Dim objSolids() As Mastercam.Database.SolidGeometry objSolids = Mastercam.Support.SearchManager.GetSolidGeometry() '-> as a test, report the number of solids found MsgBox("number of solids found: " & CStr(objSolids.Length)) '-> loop thru the array of solids, import an operation for each and add the solid to the op For intI As Integer = 0 To objSolids.Length '-> import the rough surface contour operation Dim OpImport As Mastercam.Database.Operation OpImport = Mastercam.Operations.OperationsManager.ImportOperation(strOpsFile, intOpID, True, True) '-> code here to somehow add each solid to the imported operation Next Return MCamReturn.NoErrors End Function My questions are: 1. Where in the object browser do I find the objects dealing with surface / solid tool paths. 2. What would the code look like to add the solids in my array to the drive surface of the surface rough cuts? Thanks in advance.

Good afternoon, Is it possible to call solid drill from a nethook? I have searched this forum and the object browser in NetHook2_0 in X2_MR2 with no luck. Does anyone know of alternate methods to find holes? (these are all solids translated in from CATIA and UG) Thanks, Roger
