T&P Replace Family Template

            Let me just start by saying this is a bug and I’ve documented it on idea station so you can all vote for the change.

                If you have published a TP fitting to content center and you decide to change the authoring info there is no way to update the family in content center.

                Sure, you can try the standard procedure of right-clicking on your family and use the Replace Family Template but that will not update authoring info.

Replace Family Template works (no errors) but the authoring info is not updated.

Creating a new CC family is not feasible because you then need to change all T&P styles for existing runs/routes and point them to the new family. T&P Styles uses the CC UID to track and store fittings of each style.

There is no other way except to cast a vote and to hope it gets implemented.

Here’s the link to idea station.

Handrail with Tube and Pipe

                A while back I answered a question on Autodesk forum on what would be the best way to do hand railing in Inventor.

                While I think Frame Generator is the best tool for that because you get notch, trim and other specific functions to help you out I also mentioned Tube and Pipe.

                The user got really intrigued on how I would use Tube and Pipe for hand railing especially since he wanted ball connections on all joints.

                The other benefit of making it in Tube and Pipe is the possibility exporting the results into bending machine format; read all about it here.

                This post will explore just that, a short video on how this might be accomplished with TP. If you find the quality low on the video then you can always see the original one on screencast here.

Remove Columns on Bend Table

                Some Inventor tables are hard-coded and you can’t configure and preset their format. One of this tables is Bend Table and I had an interesting request from someone to remove Bend Radius column from it.

                You can customize it when you place the table or by editing the table, however, he doesn’t want to do it for every single table he places but rather configure it once and for all.

                This is one hard-coded table which can’t be configured. I have even searched the registry to see if I can find any reference and couldn’t find any. 

                Case has been confirmed by Autodesk QA Engineers but that doesn’t mean we can’t speedup the process.

                I have written an ilogic code for you that will remove the bend radius from your table. I suggest you have this as an external rule which you can trigger with a nice form.....

Here's an example.

Here’s what the code does

And here is the code.

' Set a reference to the drawing document.
' This assumes a drawing document is active.
Dim oDrawDoc As DrawingDocument
oDrawDoc = ThisApplication.ActiveDocument

' Set a reference to the active sheet.
Dim oSheet As Sheet
oSheet = oDrawDoc.ActiveSheet

'Declare my custom table
Dim oCustomTable As CustomTable

'Set name for this table
Dim TableName As String
TableName = "TABLE"

' Process the rule, wrapping it in a transaction so the
' entire process can be undone with a single undo operation.
Dim trans As Transaction
trans = ThisApplication.TransactionManager.StartTransaction( _
        oDrawDoc, "Remove Bend Radius column from Bend Table")

For i = 1 To oSheet.CustomTables.Count
    If oSheet.CustomTables.Item(i).Title = TableName Then
        TableNr = i
        MessageBox.Show("Table named: " & TableName & " was not found on drawing", "Missing Table")
        Exit Sub
    End If

'declare the table to edit by the number found in check
oCustomTable = oSheet.CustomTables.Item(TableNr)

'remove Bend Radius column
oCustomTable.Columns.Item("Bend Radius").Delete()

'end transaction for single undo

Translucent Off via iLogic

                If you import foreign cad models you might get the import as surfaces which show up as orange, translucent objects.

                I had one the other day that I needed to import as assembly but having all surfaces translucent did not cut it for me so being lazy I had written a code to change all parts and remove transparency.

                Short and sweet, here it is:

Dim oAsmDoc As AssemblyDocument 
oAsmDoc = ThisApplication.ActiveDocument 

' Get the assembly component definition. 
Dim oAsmDef As AssemblyComponentDefinition 
oAsmDef = oAsmDoc.ComponentDefinition 

' Get all of the leaf occurrences of the assembly. 
Dim oLeafOccs As ComponentOccurrencesEnumerator 
oLeafOccs = oAsmDef.Occurrences.AllLeafOccurrences 

Dim oPartDoc As PartDocument
Dim oOcc As ComponentOccurrence 

' Process the occurrences, wrapping it in a transaction so the 
' entire process can be undone with a single undo operation. 
Dim trans As Transaction 
trans = ThisApplication.TransactionManager.StartTransaction( _ 
        oAsmDoc, "Translucent Off")

    For Each oOcc In oLeafOccs 
        oPartDoc = oOcc.Definition.Document
        Dim oWorkSurfaces As WorkSurfaces
        oWorkSurfaces = oPartDoc.ComponentDefinition.WorkSurfaces
        Dim oWorkSurface As WorkSurface
        For Each oWorkSurface In oWorkSurfaces
            oWorkSurface.Translucent = False
'end transaction

Force Sheet Orientation

                So you need to force sheet orientation in inventor and have A4 always Portrait and the rest landscape?
                This is possible out of the box and it’s working quite nicely.


                But you want to update to old drawings or want to enforce things in your company? Then we can use this code:

Dim oDrawDoc As DrawingDocument = ThisApplication.ActiveDocument
Dim oSheet As Sheet = oDrawDoc.ActiveSheet

If oSheet.Size = Inventor.DrawingSheetSizeEnum.kA4DrawingSheetSize Then
    oSheet.Orientation = Inventor.PageOrientationTypeEnum.kPortraitPageOrientation
    oSheet.Orientation = Inventor.PageOrientationTypeEnum.kLandscapePageOrientation
End If

Multiple Balloon Sets

                How can I have multiple balloon sets on same drawing? How can show project Item Number on components and subassembly drawings?

                In this case the user wanted to have dual balloons on all drawings but it works with as many balloons as you can fit in a drawing.

The first balloon will indicate current assembly Item Number, which translates to what position the item has in the current assembly and the second balloon was to show master Item Number which means what position this member has in the general, whole project, context.

He didn’t want to have dual set of documentation, one for fabrication and one for manuals because it was hard for him to maintain and update.

Three things are needed for this.

The user will place balloons on drawing as usual and we will change them for him but in order to do that we need a way of knowing which ones exactly he needs changing.

1. A new balloon style called “Pars Only”. I suggest you change the shape as well, like hexagonal type, maybe change text style too just to distinguish them better and update the code if you use a different name for the balloon.

2. A “PARTS ONLY” table but of the main assembly. Name it whatever you want but update the code.

User needs to place main assembly (project) “PARTS ONLY” parts list on the drawing so we can track and find this.

Do not filter the Parts Only table, it won’t work, there is no view for it to process. Design View reps or Ballooned Only filters won’t work.

3. iLogic code to process all “Parts Only” balloons and update value as in “PARTS ONLY” table.

You can do this with without a table but have the user browser for main iam and process BOM from that.

Here is a short video:

And here is the iLogic code:

'  Set a reference to the drawing document.

' This assumes a drawing document is active.

Dim oDrawDoc As DrawingDocument
oDrawDoc = ThisApplication.ActiveDocument

' Set a reference to the active sheet.
Dim oActiveSheet As Sheet
oActiveSheet = oDrawDoc.ActiveSheet

Dim oStyles As DrawingStylesManager
oStyles = oDrawDoc.StylesManager

Dim oCurve As DrawingCurve
'Dim oEdge As EdgeProxy
Dim oOccurrence As ComponentOccurrence 
Dim oGeometryIntent As GeometryIntent

'----------Update existing balloons on all sheets

'Ask the user if he wants to update values of all balloons (if edited some)
booleanParam = InputRadioBox("Update Parts Only balloons?: ", "Yes", "No", True, Title :="Update?")

If booleanParam = False Then
    Exit Sub
ElseIf booleanParam = True
End If

Dim oSheet As Sheet
'process all sheets
For Each oSheets In oDrawDoc.Sheets 
    '----------find the parts list
    oPartsLists = oActiveSheet.PartsLists
    'try and get the parts list form the table of this sheet
        For i=1 To oPartsLists.Count
            If oPartsLists.Item(i).Title = "PARTS ONLY" Then
                oPartsList = oPartsLists.Item(i)
                Exit For
                'do nothing
            End If
        MessageBox.Show("No parts list named 'PARTS ONLY' found on drawing", "iLogic")
    End Try    

'----------end finding parts list

    ' Iterate over each balloon on the sheet.
    For Each oBalloon In oActiveSheet.Balloons
        If oBalloon.Style.Name = "Parts Only" Then
                Dim leader As Leader
                Leader = oBalloon.Leader
                'assuming the leader is a single line segment
                Dim leaderNode As LeaderNode 
                leaderNode = leader.AllNodes(2)
                oGeometryIntent = leaderNode.AttachedEntity
                curve = oGeometryIntent.Geometry
                oEdge = curve.ModelGeometry
                oOccurrence = oEdge.ContainingOccurrence
                'get the selected item document occurrence name
                oOccDoc = oOccurrence.Definition.Document
                'get the path and file name of the selected item
                oOccFileName = oOccDoc.FullFileName
                ' Iterate over each value set (attached balloons) in a balloon.
                For Each oBalloonValueSet In oBalloon.BalloonValueSets
                    '----------find item in parts list PARTS ONLY
                    ' Iterate through the contents of the parts list.
                    Dim j As Long

Precise Circular Text Pattern

                Do you need a Precise Circular Text Pattern?

                I needed this the other day and I was a bit intrigued about the best workflow for this.

                I needed this the other day and I was a bit intrigued about the best workflow for this.

                My first thought was to do it with iFeatures. Create a prompted text iFeature and a pattern of sketch points and place this iFeature as many times as you need changing the text every time. 

                Whell... that didn’t work and I slowly realized that it will be very difficult to edit, not to mention the large number of features in the browser.

                Then I thought of doing it by creating them as separate features and wrap them to the part. This seemed complicated as well so I had a better idea.

                Create a text and emboss it to the face, except there is a trick here. In order to get exact spacing between first and last, you need to use “Exact Spacing” in the text editor.

                This way I can control the text size and yet still get precise placement.

                As always Inventor threw a spanner in the works because the exact spacing field text has only 2 (two) decimal settings and you can’t use parameter for an automatic update when you change drum diameter.

                This was still way better than any other solutions proving fast and simple.

                The original screencast can be seen here (includes commands and dialog boxes if the video bellow is not clear enough).

Precise Move Table

                Do you need to enforce Revision Table position? or any table for that matter?

                We talked about how to place and locate various tables on drawings so this is not new info but it is best if we make a post of its own so you can find it faster.

                This will help you enforce common standard and procedures when working with new recruits/students/temporary workforce.

                The code will move your revision table to lower left corner of your sheet but I did touch on how to find and use other points on drawing.

I did play with “TableDirection” “kBottomUpDirection” & “kTopDownDirection” thinking that the point coordinates will change depending on the drawing style of the table but Inventor outsmarted me (that’s not hard) and worked perfectly out of the box.

                It seems table coordinates will always start from top left corner no matter of your header position (top/bottom) or table direction (bottom up / top down), so we do need to calculate the height of the table.

On this principle, you can play with “Border.RangeBox.MinPoint”  ”Border.RangeBox.MaxPoint” or even specific x y values “Border.RangeBox.MinPoint.X” “Border.RangeBox.MinPoint.Y” to locate it in a different corner.

                This also applies to “TitleBlock.Position” or “TitleBlock.RangeBox” in case you need it next to, or on top of the titleblock.

                You can even search for table specific name if you have more than one tables on the sheet, that’s not possible with revision tables but it is with custom tables.  For example, this will search for Parts List with specific Title:

For i=1 To oPartsLists.Count
    If oPartsLists.Item(i).Title = "PARTS LIST" Then
        oPartsList = oPartsLists.Item(i)
        Exit For

                So here is the code to move Revision Table:

Dim oDrawDoc As DrawingDocument
oDrawDoc = ThisApplication.ActiveDocument

Dim oSheet As Sheet
oSheet = oDrawDoc.ActiveSheet

'if you want different positions youcan get the MinPoint.X or MaxPoint or MaxPoint.Y
'along those lines
Dim oBorderPt As Point2d
oBorderPt = oSheet.Border.RangeBox.MinPoint

Dim oRevTable As RevisionTable
'I assume you only have 1 rev table on the drawing
oRevTable = oSheet.RevisionTables.Item(1)

Dim oRevPt As Point2d
oRevPt = ThisApplication.TransientGeometry.CreatePoint2d _
            (oBorderPt.X, oBorderPt.Y  + (oRevTable.RangeBox.MaxPoint.Y - oRevTable.RangeBox.MinPoint.Y))

oRevTable.Position = oRevPt

Add Legend to Parts List

Can we add a legend to our drawing PartsList?

You can add a Custom Part on your Parts List or you can add a Virtual Part in the assembly but those will obey the Parts List format and you can’t merge the cells into a single one. I don’t suggest you add Virtual Part to BOM anyway because it will show up higher up in assemblies and I doubt anyone would want that.

What other options we have?

Create a symbol which you call and place every time. If you set the leader visible “off” it will look like a bit of text floating around but the invisible leader will allow you to attach it to views, or other elements and it will move with those by magic.

Some prefer to hardcode it on the border or titleblock but that doesn’t allow for much customization except if you use a prompted entry type field.

I don’t expect anyone to follow this but you can also manage your entire Parts List in Excel and after adding the legend to the bottom, you can place the spreadsheet as custom table on the drawing.

All this being mentioned you can add your Legend to your Parts List Title which is a single cell but you need to format your code in word, or other text editing software or even better have an iLogic code to do that for you.

If you are not iLogic fan then you can type your text in word, copy it and paste it in the Title field in Parts List editor but the next code is very easy, just give it a try...

Here is the iLogic code to add a Legend to your ParsList. It has a preset list already but it accepts user prompted values as well.

Dim oDrawDoc As DrawingDocument
oDrawDoc = ThisApplication.ActiveDocument

Dim oSheet As Sheet
oSheet = oDrawDoc.ActiveSheet

Dim oPartsLists As PartsLists

' Process the rule, wrapping it in a transaction so the 
' entire process can be undone with a single undo operation. 
Dim trans As Transaction 
trans = ThisApplication.TransactionManager.StartTransaction( _ 
        oDrawDoc, "Change Title of Parts List")
    'I assume you ony have one Parts List on the sheet
    'get current title
    oPartsLists = oSheet.PartsLists
    oTitle = oPartsLists.Item(1).Title
    'ask for Legend
    oLegend = InputBox("Enter Legend", "Legend", "Mach=Machined, Fab=Fabricated")

    'set title
    oNewTitle = oTitle + _
                vbLf + _
                vbLf + oLegend
    oPartsLists.Item(1).Title = oNewTitle
'finish the transaction
