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.
