1 AutoCAD and VBA Integration with Microsoft Office Presented by Jerry Winters About this Class Classes are taught on AutoCAD / Excel Integration. Classes are taught on AutoCAD / Access Integration. This class will utilize most Microsoft Office applications. Specifically, we will use Microsoft Excel, Microsoft Word, Microsoft Outlook, Microsoft Access, and Microsoft FrontPage. These tools will be used to create a solution to allow us to standardize an AutoCAD drawing, request quotes from suppliers, process the quotes, and show resulting data for use on a corporate Intranet. About the Instructor Jerry Winters has been using AutoCAD since He has written several books on programming AutoCAD with VBA and will be releasing his AutoCAD 2004 VBA book soon. Jerry provides VBA training as well as customization services for customers all over the United States as well as other countries on Earth. He has yet to teach on other planets in the solar system but is not counting out the possibility in the future. This is his second year teaching at Autodesk University. Had his 5th son, Nathan not been born the night before AU 2001, this would have been his third year. His first daughter, Olivia was born October 28th, 2003, so he is very happy to be here this year. He has been happily married for 12 years. If you are counting, that makes 5 sons, 1 daughter, and 1 wife. Also, 8 chickens, 1 cat, 1 turkey named Thanksgiving (he isn t feeling very well) and 1 turkey named Christmas (she is very cold right now). Jerry and his 3 oldest sons hold Tae Kwon Do Black Belts. To contact Jerry, please him at jerryw@vbcad.com or visit his website: Pg. 1

2 The file C:\Program Files\AutoCAD 2004\Sample\8th floor furniture.dwg is installed with AutoCAD We will use this file for this class. We will pretend that we have received this file from a 3rd party. The first thing we will do is a little standardization. Pg. 2

The first thing we notice is the block names of some of the inserted blocks. Let s get rid of much of the name and simplify the name. This block that is listed should be named DESK_CHAIR.

3 The first thing we notice is the block names of some of the inserted blocks. Let s get rid of much of the name and simplify the name. This block that is listed should be named DESK_CHAIR. Sub ChangeBlockName() Dim MyBlk As AcadBlock For Each MyBlk In ThisDrawing.Blocks If Left(MyBlk.Name, 1) <> "*" Then If InStr(1, MyBlk.Name, "http") > 0 Then MyBlk.Name = Mid(MyBlk.Name, InStrRev(MyBlk.Name, ".") + 1) This code looks for the string http in the name of the block. If found, we take everything to the right of the left-most period in the block name. The next thing we notice is that the blocks we want to work with have a single attribute. Our standard dictates that we have three attributes named dbid, cost, and supplier. How do you add an attribute to a block that is already inserted? One way is to add an attribute to the block definition and swap out the old inserted blocks with the newly defined blocks. Sub AddAtts() Dim BlkDef As AcadBlock Dim InsPt(0 To 2) As Double For Each BlkDef In ThisDrawing.Blocks If Left(BlkDef.Name, 1) <> "*" And BlkDef.IsXRef = False Then If MsgBox("Add attributes to " & BlkDef.Name & "?", vbyesno) = vbyes Then BlkDef.AddAttribute 1, acattributemodeinvisible, "dbid", InsPt, "dbid", "" BlkDef.AddAttribute 1, acattributemodeinvisible, "cost", InsPt, "cost", "" BlkDef.AddAttribute 1, acattributemodeinvisible, "supplier", InsPt, "supplier", "" Pg. 3

4 The macro AddAtts asks if we want to add our standard attributes to each block. Clicking Yes means the attributes will be added to the block. Clicking No means the block will not be modified. Sub AskToSwap() Dim MySS As AcadSelectionSet Dim BlkRef As AcadBlockReference Dim GrpC(0 To 1) As Integer Dim GrpV(0 To 1) As Variant Dim AcadBlk As AcadBlock GrpC(0) = 0: GrpV(0) = "INSERT" For Each AcadBlk In ThisDrawing.Blocks If Left(AcadBlk.Name, 1) <> "*" And AcadBlk.IsXRef = False Then If MsgBox("Swap block " & AcadBlk.Name & "?", vbyesno) = vbyes Then Set MySS = ThisDrawing.SelectionSets.Add("BlkSwap") GrpC(1) = 2: GrpV(1) = AcadBlk.Name MySS.Select acselectionsetall,,, GrpC, GrpV For Each BlkRef In MySS SwapBlocks BlkRef, AcadBlk.Name MySS.Delete Sub SwapBlocks(MyBlk As AcadBlockReference, BlockToReplaceWith As String) Dim TmpBlk As AcadBlockReference Set TmpBlk = ThisDrawing.ModelSpace.InsertBlock(MyBlk.InsertionPoint, _ BlockToReplaceWith, MyBlk.XScaleFactor, MyBlk.YScaleFactor, _ MyBlk.ZScaleFactor, MyBlk.Rotation) TmpBlk.Layer = MyBlk.Layer MyBlk.Delete The macro AskToSwap goes through each block in the drawing and asks if you want to swap the existing insertions of the block with the existing definitions of the blocks. If the user says Yes to the message box, we create a selection set of all blocks of that name and call the SwapBlocks procedure to do the swap. Pg. 4

5 Sub GetRefs() Dim MyBlk As AcadBlock Dim MyExcel As Excel.Application Dim MySht As Excel.worksheet Dim CurRow As Long Dim MySS As AcadSelectionSet Dim GrpC(0 To 1) As Integer Dim GrpV(0 To 1) As Variant CurRow = 1 Set MyExcel = GetObject(, "Excel.Application") Set MySht = MyExcel.ActiveSheet Dim CurCol As Long Dim BlkRef As AcadBlockReference For Each MyBlk In ThisDrawing.Blocks If Left(MyBlk.Name, 1) <> "*" And MyBlk.IsXRef = False Then If MsgBox("Export Block " & MyBlk.Name & "?", vbyesno) = vbyes Then CurCol = 3 GrpC(0) = 0: GrpV(0) = "INSERT" GrpC(1) = 2: GrpV(1) = MyBlk.Name Set MySS = ThisDrawing.SelectionSets.Add("GetRefs") MySS.Select acselectionsetall,,, GrpC, GrpV For Each BlkRef In MySS MySht.Cells(CurRow, 1) = MyBlk.Name MySht.Cells(CurRow, 2).NumberFormat = "@" MySht.Cells(CurRow, 2) = BlkRef.Handle Dim cadent As AcadEntity CurCol = 3 For Each cadent In MyBlk If cadent.objectname = "AcDbAttributeDefinition" Then MySht.Cells(CurRow, CurCol).AddComment MySht.Cells(CurRow, CurCol).Comment.Visible = False MySht.Cells(CurRow, CurCol).Comment.Text cadent.tagstring CurCol = CurCol + 1 CurRow = CurRow + 1 MySS.Delete Now that the blocks have been updated, we need a way to update the attributes of the blocks. We will do this by bringing all of the blocks and their attributes into Excel. The Attribute tag name is entered in Excel as a comment so we know which cell relates to which attribute. Pg. 5

6 The last attribute column is for the supplier. Excel makes it easy to copy and paste suppliers down the list of inserted blocks. Let s sort the columns now based on the supplier first, and then by the block name. Pg. 6

Sub UpdateAttsFromExcel() Dim MyBlk As AcadBlockReference Dim MyExcel As Excel.Application Dim MySht As Excel.worksheet Dim CurRow As Long CurRow = 1 CurCol = 3 Set MyExcel = GetObject(, "Excel.

7 Sub UpdateAttsFromExcel() Dim MyBlk As AcadBlockReference Dim MyExcel As Excel.Application Dim MySht As Excel.worksheet Dim CurRow As Long CurRow = 1 CurCol = 3 Set MyExcel = GetObject(, "Excel.Application") Set MySht = MyExcel.ActiveSheet While MySht.Cells(CurRow, 2) <> "" Dim MyComm As Comment Dim IsGood As Boolean Set MyComm = MySht.Cells(CurRow, CurCol).Comment While MyComm Is Nothing = False Set MyBlk = ThisDrawing.HandleToObject(MySht.Cells(CurRow, 2)) atts = MyBlk.GetAttributes For I = LBound(atts) To UBound(atts) If atts(i).tagstring = MySht.Cells(CurRow, CurCol).Comment.Text Then If MySht.Cells(CurRow, CurCol) <> "" Then atts(i).textstring = MySht.Cells(CurRow, CurCol) I = UBound(atts) + 1 I CurCol = CurCol + 1 Set MyComm = MySht.Cells(CurRow, CurCol).Comment Wend CurRow = CurRow + 1 CurCol = 3 Wend This macro will take the data we have in Excel and update the blocks in AutoCAD to reflect the values in Excel. After the macro is run, the Supplier attribute is filled with whatever was in Excel. Pg. 7

8 It makes sense to have bi-directional updating of data so we will create a macro that updates values in Excel based on changes to attributes in AutoCAD. Sub UpdateAttsFromAutoCAD() Dim MyBlk As AcadBlockReference Dim MyExcel As Excel.Application Dim MySht As Excel.worksheet Dim CurRow As Long CurRow = 1 CurCol = 3 Set MyExcel = GetObject(, "Excel.Application") Set MySht = MyExcel.ActiveSheet While MySht.Cells(CurRow, 2) <> "" Dim MyComm As Comment Dim IsGood As Boolean Set MyComm = MySht.Cells(CurRow, CurCol).Comment While MyComm Is Nothing = False Set MyBlk = ThisDrawing.HandleToObject(MySht.Cells(CurRow, 2)) atts = MyBlk.GetAttributes For I = LBound(atts) To UBound(atts) If atts(i).tagstring = MySht.Cells(CurRow, CurCol).Comment.Text Then MySht.Cells(CurRow, CurCol) = atts(i).textstring I = UBound(atts) + 1 I CurCol = CurCol + 1 Set MyComm = MySht.Cells(CurRow, CurCol).Comment Wend CurRow = CurRow + 1 CurCol = 3 Wend So far we have worked with Microsoft Excel. We now need to take the data we have exported into Excel and request quotes from the suppliers specified in the blocks. Pg. 8

9 Sub PrepareQuotes() Dim MyExcel As Excel.Application Dim MySht As Excel.worksheet Dim CurRow As Long CurRow = 1 CurCol = 3 Set MyExcel = GetObject(, "Excel.Application") Set MySht = MyExcel.ActiveSheet Dim BlkCnt As Long Dim BlkName As String Dim SupName As String SupName = MySht.Cells(1, 6) BlkName = MySht.Cells(1, 1) PrepareDoc While MySht.Cells(CurRow, 2) <> "" If MySht.Cells(CurRow, 6) <> SupName Then AddBlockToQuote BlkName, BlkCnt SaveDoc SupName PrepareDoc BlkName = MySht.Cells(CurRow, 1) SupName = MySht.Cells(CurRow, 6) BlkCnt = 1 Else If MySht.Cells(CurRow, 1) <> BlkName Then AddBlockToQuote BlkName, BlkCnt BlkName = MySht.Cells(CurRow, 1) BlkCnt = 1 Else BlkCnt = BlkCnt + 1 CurRow = CurRow + 1 Wend AddBlockToQuote BlkName, BlkCnt SaveDoc SupName I have put the procedures we need to create in BOLD. They will follow this page. Pg. 9

10 Sub SaveDoc(Supplier As String) Dim MyWord As Word.Application Dim MyWDoc As Word.Document Set MyWord = GetObject(, "Word.Application") Set MyWDoc = MyWord.ActiveDocument MyWDoc.SaveAs "c:\au2003\office\out\" & Supplier & ".doc" MyWDoc.Close Sub PrepareDoc() Dim MyWord As Word.Application Dim MyWDoc As Word.Document Set MyWord = GetObject(, "Word.Application") Set MyWDoc = MyWord.Documents.Add("RequestForQuote.dot") Sub AddBlockToQuote(BName As String, BCnt As Long) Dim MyWord As Word.Application Dim MyWDoc As Word.Document Set MyWord = GetObject(, "Word.Application") Set MyWDoc = MyWord.ActiveDocument Dim MyTable As Table Set MyTable = MyWDoc.Tables(1) 'Insert Row and Populate MyTable.Cell(MyTable.Rows.Count, 1).Select MyWord.Selection.InsertRowsBelow 1 MyTable.Cell(MyTable.Rows.Count, 1).Range.Text = MyTable.Rows.Count - 1 MyTable.Cell(MyTable.Rows.Count, 2).Range.Font.Bold = False MyTable.Cell(MyTable.Rows.Count, 3).Range.Font.Bold = False MyTable.Cell(MyTable.Rows.Count, 4).Range.Font.Bold = False MyTable.Cell(MyTable.Rows.Count, 5).Range.Font.Bold = False MyTable.Cell(MyTable.Rows.Count, 4).Range.ParagraphFormat.Alignment = 0 'Left MyTable.Cell(MyTable.Rows.Count, 2).Range.Text = BCnt MyTable.Cell(MyTable.Rows.Count, 4).Range.Text = BName The code we have so far will create Microsoft Word documents based on a template named RequestForQuote.dot. We update the table identifying the items we want the supplier to quote. The files are saved to c:\au2003\office\out. When our suppliers return the documents, we will put them in the in folder. Now that we have the Word documents created, we need to them. Let s use Microsoft Outlook to them out and add tasks for each to make sure we follow up on the request for quotes. Pg. 10

$Sub SendRFQ() Dim MyFSO As New FileSystemObject Dim MyFolder As Folder Dim MyFile As File Set MyFolder = MyFSO.GetFolder("c:\au2003\office\in") For Each MyFile In MyFolder.Files Select Case MyFile.$

11 Sub SendRFQ() Dim MyFSO As New FileSystemObject Dim MyFolder As Folder Dim MyFile As File Set MyFolder = MyFSO.GetFolder("c:\au2003\office\in") For Each MyFile In MyFolder.Files Select Case MyFile.Type Case "Microsoft Word Document" Select Case UCase(MyFile.Name) Case "HP.DOC" Doc "hp@vbcad.com", MyFile.Path, "HP" Case "HERMANMILLER.DOC" Doc "hermanmiller@vbcad.com", MyFile.Path, "Herman Miller" Case "AT&T.DOC" Doc "att@vbcad.com", MyFile.Path, "AT&T" End Select End Select Sub Doc(MailAddress As String, FilePath As String, Company As String) Dim MyOut As New Outlook.Application Dim MyMail As MailItem Set MyMail = MyOut.CreateItem(olMailItem) MyMail.To = MailAddress MyMail.Subject = "Please provide a quote for the items included in this RFQ." MyMail.Attachments.Add FilePath MyMail.Body = "Thank you." & vbcr & vbcr & "Jerry Winters" MyMail.Send Dim MyTask As TaskItem Set MyTask = MyOut.CreateItem(olTaskItem) MyTask.Body = "Look for returned request from " & Company MyTask.DueDate = DateAdd("d", 4, Now) MyTask.Subject = "RFQ sent to " & Company MyTask.Save I have bolded the lines where the is sent and the task is saved to Outlook. At this point, the supplier has our RFQ. The supplier needs to enter the costs in the provided space in the table in the RFQ. The supplier simply needs to enter the value in the Price column, save it, and it back to us. When it comes back, we place the file in the c:\au2003\office\in directory. Pg. 11

12 Sub GetPricingFromWord() Dim MyFSO As New FileSystemObject Dim MyFolder As Folder Dim MyFile As File Dim MyWord As Word.Application Dim MyWDoc As Word.Document Set MyWord = GetObject(, "Word.Application") Set MyFolder = MyFSO.GetFolder("c:\au2003\office\in") For Each MyFile In MyFolder.Files Select Case MyFile.Type Case "Microsoft Word Document" Set MyWDoc = MyWord.Documents.Open(MyFile.Path) Dim MyTable As Table Set MyTable = MyWDoc.Tables(1) For I = 2 To MyTable.Rows.Count Dim ItmCost As Double Dim BlockName As String ItmCost = Left(MyTable.Cell(I, 5).Range.Text, _ InStr(1, MyTable.Cell(I, 5).Range.Text, vbcr) - 1) BlockName = Left(MyTable.Cell(I, 4).Range.Text, _ InStr(1, MyTable.Cell(I, 4).Range.Text, vbcr) - 1) Select Case UCase(MyFile.Name) Case "HP.DOC" UpdateCost BlockName, ItmCost, "HP" Case "HERMANMILLER.DOC" UpdateCost BlockName, ItmCost, "Herman Miller" Case "AT&T.DOC" UpdateCost BlockName, ItmCost, "AT&T" End Select I MyWDoc.Close False End Select Exit Sub Sub UpdateCost(BName As String, BCost As Double, Supplier As String) Dim MySS As AcadSelectionSet Dim GrpC(0 To 1) As Integer Dim GrpV(0 To 1) As Variant Dim MyBlk As AcadBlockReference GrpC(0) = 0: GrpV(0) = "INSERT" GrpC(1) = 2: GrpV(1) = BName Set MySS = ThisDrawing.SelectionSets.Add("UpdateCost") MySS.Select acselectionsetall,,, GrpC, GrpV For Each MyBlk In MySS atts = MyBlk.GetAttributes atts(2).textstring = BCost SendToDB MyBlk.Name, MyBlk.Handle, BCost, Supplier MySS.Delete Pg. 12

$Sub SendToDB(BName As String, BHandle As String, BCost As Double, Supplier As String) Dim MyDB As New ADODB.Connection Dim MyRS As New ADODB.Recordset MyDB.Open "File name=c:\udls\au2003office.$

13 Sub SendToDB(BName As String, BHandle As String, BCost As Double, Supplier As String) Dim MyDB As New ADODB.Connection Dim MyRS As New ADODB.Recordset MyDB.Open "File name=c:\udls\au2003office.udl" MyDB.Execute "Delete from Blocks Where BHandle = '" & BHandle & "'" MyRS.Open "Blocks", MyDB, 1, 2 MyRS.AddNew MyRS("BHandle") = BHandle MyRS("BName") = BName MyRS("BCost") = BCost MyRS("BSupplier") = Supplier MyRS.Update MyRS.Close MyDB.Close Set MyRS = Nothing Set MyDB = Nothing In order for this code to work, we need to create a database and a udl file. Here is the database. One table is all that is necessary. The necessary fields are shown here. Pg. 13

14 Create a udl file named c:\udls\au2003office.udl and point it to the access database we just created. Running the macro GetPricingFromWord populates the database., we want to make the database viewable from our company intranet. This involves creating an ASP file to display the database data. We will do this in FrontPage. <% response.expires = 0 %> <html> <head> <meta http-equiv="content-language" content="en-us"> <meta http-equiv="content-type" content="text/html; charset=windows-1252"> <meta name="generator" content="microsoft FrontPage 4.0"> <meta name="progid" content="frontpage.editor.document"> <title>new Page 1</title> </head> <body> <table border="1" width="700"> <tr> <td width="100">qty</td> <td width="300">item</td> <td width="100">supplier</td> <td width="100">cost</td> <td width="100">ext. Cost</td> </tr> <% Dim MyDB Dim MyRS Dim TotCost Set MyDB = Server.CreateObject("ADODB.Connection") Set MyRS = Server.CreateObject("ADODB.Recordset") MyDB.Open "File name=c:\udls\au2003office.udl" MyRS.Open "Select * from Blocks Order By BSupplier, BName", MyDB, 1, 2 BName = MyRS("BName") BSupplier = MyRS("BSupplier") BlockCnt = 1 BlockCost = MyRS("BCost") While MyRS.EOF = False If MyRS("BName") <> BName Then response.write "<tr>" & vbcr response.write "<td>" & BlockCnt & "</td>" & vbcr response.write "<td>" & BName & "</td>" & vbcr response.write "<td>" & BSupplier & "</td>" & vbcr response.write "<td align=""right"">" & FormatCurrency(BlockCost, 0) & "</td>" & vbcr response.write "<td align=""right"">" & FormatCurrency(BlockCnt * BlockCost, 0) & "</td>" & vbcr TotCost = totcost + BlockCnt * BlockCost response.write "</tr>" & vbcr BlockCost = MyRS("BCost") BName = MyRS("BName") BSupplier = MyRS("BSupplier") Else BlockCnt = BlockCnt + 1 MyRS.Move Wend MyRS.Close MyDB.Close Set MyRS = Nothing Set MyDB = Nothing response.write "<tr><td colspan=4><b>total Cost</td><td align=""right""><b>" & _ FormatCurrency(TotCost, 0) & "</td></tr>" %> </table> </body> </html> That s the code. Name the file showcost.asp. View the file in your web browser now. On my machine, it is Pg. 14

15 This is the result of our ASP file showcost.asp. As our Word quotes come in or change, simply re-run the appropriate macro and the web page will automatically update based on the new values. Pg. 15

16 This concludes the content for this class. If you are reading this but didn t attend Autodesk University, you missed out! Microsoft Office products can be used to create powerful applications. Why count blocks when AutoCAD can do it? Why enter pricing manually when you can pull it from Word? Once you get your data, making it available to anyone in your organization via your intranet is simple. Feel free to modify the code here to meet your needs. Perhaps 3 additional attributes are not enough. You may want more. We hard-coded some things such as the suppliers we are using. This meets our needs for this presentation but you will probably want to put supplier info in a database. Actually, you probably already have your supplier info in a database. Thanks again for taking the time to attend this class. If you didn t, I hope to see you next year at Autodesk University 2004!!!! Jerry Winters President, VB CAD jerryw@vbcad.com Pg. 16
