In the Nethook API there is a property under OperationsManager called "JobSetupStockSize" The API says it returns a Point3D object. Might have a look at that.

Thanks for the replies. The problem is not knowing which way to round. I appreciate the example on how to use a function Jeff. I will do something similar with a bunch of if statements to get the output I need.

Is there a function to round UP a decimal to the nearest integer? I am in need of rounding numbers like 1.415 to 2, 3.46 to 4, etc. Any help with getting my G-Code more accurate would be greatly appreciated. Thanks.

Thanks Jeff! Worked like a charm!

How do add a quotation mark (inch mark) manually in the middle of a string? Any help would be much appreciated.

That did it. Thanks!

I was going through the API help and was having a hard time finding the method for using Mastercam's "Merge" command. Does it exist in VB.Net?

Amen to that! That's the method I use. We have anywhere from 1 to 200 configurations in a single model in Solidworks and using Mastercam for Solidworks has saved me countless hours!

I've been looking in the API help and can't seem to find an API call for a Transform operation. Is there an interface in the NETHook API to tell if an operation is a transform op? If so, how can I tell if it has any operations selected? Any help would be appreciated. Thanks!

Thanks for the reference Roger. I think that is close to what I'm looking for. I tried the RefreshOperationsManager command after setting the RefreshEnabled property to True, but it didn't work. I will research the API info to see if I can find a method that works. Thanks again for the help. I'll keep you posted as I'm able to find time to work on this project.

Nethook. Mcam 2017.

I'm writing a loop that deletes certain operations if they meet certain criteria and I'm wondering if there is a refresh command that I need to do after the loop is finished? Currently after the loop is finished, the operation id numbers don't re-order themselves like they do if you delete an operation manually.

Thanks Mick. I had thought about that but I figured that might cause extra processing time especially if there were a lot of 3D toolpaths. Here is what I ended up with: For i As Integer = 0 To UBound(ops) Dim op As Mastercam.Database.Operation = CType(ops(i), Mastercam.Database.Operation) If Not op Is Nothing Then If op.Type = 4 Then If op.Selected = False Then op.Selected = True op.Commit() op.Regenerate() End If Else If op.Selected = True Then op.Selected = False op.Commit() op.Regenerate() End If End If End If Next i I tried to only call the operation's change in selection if it was needed to keep the regenerate time to a minimum. Thanks again.

Hello, I'm wondering if there is an API call that I'm missing when trying to unselect certain ops. I'm adding to a custom VB.Net Nethook. I'm looping through the list of operations and trying to unselect certain ones with this code: Dim ops As Array = Mastercam.Support.SearchManager.GetOperations().ToArray If ops.Length = 0 Then Exit Sub For i As Integer = 0 To UBound(ops) Dim op As Mastercam.Database.Operation = CType(ops(i), Mastercam.Database.Operation) If Not op Is Nothing Then If op.Type = 4 Then op.Selected = True Else op.Selected = False End If op.Commit() End If Next i Problem I'm running into is if I call op.Commit() then it marks the ops I want to unselect dirty. If I leave the op.Commit() code out then the code doesn't do anything. Am I missing something?

Thanks Roger! I didn't have the current NetHook API help. Thanks for the link!

Thanks Mick, I was able to find the current directory for the part file. But I can't find where to find this property:

Hello, I was wondering if there is a way to get the directory for the current open file in VB.Net? I am also trying to obtain the "Toolpath Directory" from the Group Manager. I found how to loop through all the groups but didn't see a method for extracting the information I need. Any help would be appreciated. Thanks

Ok. Thanks for the quick response Colin. I'll look into adding it to my NetHook library.

Hello, I'm trying to add a switch in the header of our post that turn on Force Tool Change for every operation but am having trouble with getting it to come out right. I found this in the header: frcetoolch : 1 #Force toolchange at each operation? 0 = No, 1 = Yes But I cannot find the variable: frcetoolch anywhere else in the post. My company uses a modified version of the MP Master. Any help would be appreciated. Thanks

Ok, thanks Mick. I'll just have to let the guys know that they won't be able to use it on empty or unnamed levels.

I'm trying to create a NetHook that will renumber levels like the "Renumber Tools" does in the toolpaths manager. The programmers here want to be able to renumber levels based on these options: All Levels Visible Levels Non Visible Levels I'm just trying to make sure the NetHook accounts for everything so I don't have to skip levels that don't have geometry or a name assigned to them.

Hello, I'm starting a new NetHook and saw how to get a list of levels in a NetHook example project. But I was having trouble locating a way to get a list of all the levels even if they do not contain geometry or a name. Is there an API call for this? I've been looking through the API Reference Guide but have had trouble finding anything. Any help would be greatly appreciated. Thanks.

I sent the project with a test file. I appreciate the help. Thanks.

Thanks Mick! I was missing the "SetChainArray". Only problem I'm having is this works for when I chain off of wire geometry that I draw myself in Mastercam or curves that I extract from the edges of the solid model, but it doesn't work if I chain directly from the solid itself. Is there a way of checking what kind of entity is used for the chain? Because right now it is deleting the chain if a solid edge is used.

I am trying to reverse the chains, and before reversing the chains, store in a variable if the operation is using left or right cutter comp. Then after reversing the chain set the cutter comp back to what it was previously. This is what I have so far: Public Overrides Function Run(ByVal param As Integer) As MCamReturn 'Make sure there are operations to modify Dim ops As Array = Mastercam.Support.SearchManager.GetOperations().ToArray If ops.Length = 0 Then Debug.WriteLine("There Are No Operations To Modify") Return MCamReturn.FunctionExit End If Dim bSelect As Boolean = False 'Loop through all operations to see if there are any selected For i As Integer = 0 To UBound(ops) Dim op As Mastercam.Database.Operation = CType(ops(i), Mastercam.Database.Operation) If Not op Is Nothing Then If op.Selected = True Then bSelect = True Exit For End If End If Next i 'If there are no selected operations then let's exit If bSelect = False Then Debug.WriteLine("There Are No Selected Operations To Modify") Return MCamReturn.FunctionExit End If 'Process all selected operations Dim bSuccess As Boolean = LoopThroughSelectedOps(ops) If bSuccess = True Then MsgBox("Chains Reversed And Flipped") Else MsgBox("Error Reversing Chains") End If Return MCamReturn.NoErrors End Function Here is the code from my module: Public Sub ReverseChains(ByVal OpToRegen As Mastercam.Database.Operation, ByVal chains As Array) If chains.Length = 0 Then Exit Sub For i As Integer = 0 To UBound(chains) Dim chain = CType(chains(i), Mastercam.Database.Chain) If chain.Direction = Mastercam.Database.Types.ChainDirectionType.Clockwise Then chain.Direction = Mastercam.Database.Types.ChainDirectionType.CounterClockwise ElseIf chain.Direction = Mastercam.Database.Types.ChainDirectionType.CounterClockwise Then chain.Direction = Mastercam.Database.Types.ChainDirectionType.Clockwise End If OpToRegen.Commit() OpToRegen.Regenerate() Next i End Sub Public Function LoopThroughSelectedOps(ByVal OpsToProcess As Array) As Boolean Dim TheAnswer As Boolean = False If OpsToProcess.Length = 0 Then TheAnswer = False Return TheAnswer Exit Function End If For i As Integer = 0 To UBound(OpsToProcess) Dim TheOp As Mastercam.Database.Operation = CType(OpsToProcess(i), Mastercam.Database.Operation) If TheOp IsNot Nothing Then If TheOp.Selected = True Then If TheOp.Type = Mastercam.Database.Types.OperationType.Contour Then Dim ContourOp As Mastercam.Operations.ContourOperation = CType(TheOp, Mastercam.Operations.ContourOperation) ReverseChains(TheOp, ContourOp.GetChainArray) 'Dim ChainArray = ContourOp.GetChainArray End If 'End of Contour Operation type if If TheOp.Type = Mastercam.Database.Types.OperationType.Pocket Then Dim PocketOp As Mastercam.Operations.PocketOperation = CType(TheOp, Mastercam.Operations.PocketOperation) ReverseChains(TheOp, PocketOp.GetChainArray) End If 'End of Pocket Operation type if If TheOp.Type = Mastercam.Database.Types.OperationType.SlotMill Then Dim SlotMillOp As Mastercam.Operations.SlotMillOperation = CType(TheOp, Mastercam.Operations.SlotMillOperation) ReverseChains(TheOp, SlotMillOp.GetChainArray) End If 'End of SlotMill Operation type if End If 'End of TheOp being selected if End If 'End of TheOp being nothing if Next i Return TheAnswer End Function So far I am just trying to do the reverse chain part and when I debug the current code I have it seems to delete the chain rather than reversing it.
