| 10 | +## Overview |
| 11 | +- In this tutorial, I'll show you how to use Visual Basic script to create a STAAD addin |
| 12 | +- What is User Tools? |
| 13 | + - STAAD User Tools allows you to extend STAAD functionality using Visual Basic script |
| 14 | + - You can access it from Utilities > User Tools |
| 15 | +- Why use this method? |
| 16 | + - Doesn't require any setup or external tools; it's built into STAAD |
| 17 | + - Better workflow, since you can't directly run your script from STAAD |
| 18 | + - It's older technology with limited functionality, making it more LLM friendly |
| 19 | +- I am assuming that: |
| 20 | + - You have basic knowledge of Visual Basic script and know how to add modules and create new subs |
| 21 | + - Keep in mind that Visual Basic script is a bit different from Excel VBA; syntax is similar, but VBA has much more functionality |
| 22 | + |
| 23 | +## Setup |
| 24 | +- Create a new text file with *.vbs extension |
| 25 | +- For this tutorial, I am creating `Test.vbs` file |
| 26 | +- Add the sample code below and save the file |
| 27 | +- Open any STAAD model, go to Utilities > User Tools > Configure |
| 28 | +- Add a new menu item, name it "Test VBS", and in the command input, select the `Test.vbs` file and click OK to save |
| 29 | +- Now you can run this code from Utilities > User Tools > User Tools > `Test VBS` |
| 30 | + |
| 31 | +```vb |
| 32 | +Sub Main |
| 33 | + MsgBox "Test.vbs is running successfully!", vbInformation, "Test Script" |
| 34 | +End Sub |
| 35 | +``` |
| 36 | + |
| 37 | + |
| 38 | + |
| 39 | +## Get Inputs |
| 40 | + |
| 41 | +### Input Box |
| 42 | +- You can use an input box to get single inputs from the user |
| 43 | +- By default, it will return a string, so you have to convert it to double or integer as per your requirements |
| 44 | + |
| 45 | +```vb |
| 46 | +Sub Main() |
| 47 | + Dim inputValue As String |
| 48 | + inputValue = InputBox("Text", "Input Box") |
| 49 | + |
| 50 | + MsgBox inputValue, vbInformation, "Input Received" |
| 51 | +End Sub |
| 52 | +``` |
| 53 | + |
| 54 | +### User Form |
| 55 | +- More suitable for multiple inputs |
| 56 | +- You can refer to this video for more complex code: [Modelling Intze Tank Geometry using User Tool in STAAD.Pro](https://www.youtube.com/watch?v=Az1E9Qaq4UY) |
| 57 | + |
| 58 | +```vb |
| 59 | +Sub Main() |
| 60 | + |
| 61 | +Begin Dialog ModelInputs 200,140,"Model Inputs" ' %GRID:10,7,1,1 |
| 62 | + GroupBox 10,0,180,105,"Geometry Inputs",.GeometryInputsGroupBox |
| 63 | + Text 25,20,70,14,"Length" |
| 64 | + TextBox 100,20,70,14,.LengthTextBox |
| 65 | + Text 25,50,70,14,"Width" |
| 66 | + TextBox 100,50,70,14,.WidthTextBox |
| 67 | + Text 25,80,70,14,"Height" |
| 68 | + TextBox 100,80,70,14,.HeightTextBox |
| 69 | + OKButton 20,110,80,20,.OKButton |
| 70 | + CancelButton 110,110,80,20,.CancelButton |
| 71 | +End Dialog |
| 72 | + |
| 73 | +'Create new dialog instance |
| 74 | +Dim dlg As ModelInputs |
| 75 | +dlg.LengthTextBox = "10" |
| 76 | +dlg.WidthTextBox = "5" |
| 77 | +dlg.HeightTextBox = "3" |
| 78 | + |
| 79 | +Dim result As Integer |
| 80 | +result = Dialog (dlg) |
| 81 | + |
| 82 | +Dim volume As Double |
| 83 | +If result = -1 Then |
| 84 | + volume = CDbl(dlg.LengthTextBox) * CDbl(dlg.WidthTextBox) * CDbl(dlg.HeightTextBox) |
| 85 | + MsgBox "Length: " & dlg.LengthTextBox & vbCrLf & _ |
| 86 | + "Width: " & dlg.WidthTextBox & vbCrLf & _ |
| 87 | + "Height: " & dlg.HeightTextBox & vbCrLf & _ |
| 88 | + "Volume: " & volume |
| 89 | +End If |
| 90 | + |
| 91 | +End Sub |
| 92 | +``` |
| 93 | + |
| 94 | +## Generate Model |
| 95 | +- You can use this post [Automate STAAD model from Excel using OpenSTAAD](/posts/openstaad-generate-model) for the full version |
| 96 | + |
| 97 | +```vb |
| 98 | +Sub Main |
| 99 | + 'Create OpenSTAAD Object |
| 100 | + Dim objOpenSTAAD As Object |
| 101 | + Set objOpenSTAAD = GetObject(, "StaadPro.OpenSTAAD") |
| 102 | + |
| 103 | + 'Add nodes with node IDs 1 and 2 |
| 104 | + objOpenSTAAD.Geometry.CreateNode 1, 0, 0, 0 |
| 105 | + objOpenSTAAD.Geometry.CreateNode 2, 3#, 0#, 0# |
| 106 | + |
| 107 | + 'Add beam with ID 1 connecting nodes 1 and 2 |
| 108 | + objOpenSTAAD.Geometry.CreateBeam 1, 1, 2 |
| 109 | + |
| 110 | + 'Create rectangular section |
| 111 | + Dim width As Double, depth As Double |
| 112 | + Dim beamNo As Long |
| 113 | + Dim sectionPropertyNo As Long |
| 114 | + width = 0.3 |
| 115 | + depth = 0.3 |
| 116 | + beamNo = 1 |
| 117 | + sectionPropertyNo = objOpenSTAAD.Property.CreatePrismaticRectangleProperty(depth, width) |
| 118 | + objOpenSTAAD.Property.AssignBeamProperty beamNo, sectionPropertyNo |
| 119 | + |
| 120 | + 'Create fixed support |
| 121 | + Dim supportNo As Long |
| 122 | + supportNo = objOpenSTAAD.Support.CreateSupportFixed |
| 123 | + |
| 124 | + 'Assign support at nodes 1 and 2 |
| 125 | + objOpenSTAAD.Support.AssignSupportToNode 1, supportNo |
| 126 | + objOpenSTAAD.Support.AssignSupportToNode 2, supportNo |
| 127 | + |
| 128 | + ' Clean up |
| 129 | + Set objShell = Nothing |
| 130 | + Set objOpenSTAAD = Nothing |
| 131 | +End Sub |
| 132 | +``` |
| 133 | + |
| 134 | +## Extract Results |
| 135 | +- This is sample code to display node results |
| 136 | +- I am using fake data to display a report table |
| 137 | +- You can use the OpenSTAAD API to extract results as per your requirements |
| 138 | +- You can refer to this post for sample code on how to extract results using OpenSTAAD: [How to Extract Results from STAAD to Excel Using VBA](/posts/staad-excel-extract-results) |
| 139 | + |
| 140 | +```vb |
| 141 | +Sub Main() |
| 142 | +'Create OpenSTAAD Object |
| 143 | +Dim objOpenSTAAD As Object |
| 144 | +Set objOpenSTAAD = GetObject(, "StaadPro.OpenSTAAD") |
| 145 | + |
| 146 | +Dim reportID As Long, tableID As Long, numRows As Long, numCols As Long |
| 147 | + |
| 148 | +numRows = 5 |
| 149 | +numCols = 2 |
| 150 | + |
| 151 | +' Create report |
| 152 | +reportID = objOpenSTAAD.Table.CreateReport("Reports") |
| 153 | + |
| 154 | +' Add table to report |
| 155 | +tableID = objOpenSTAAD.Table.AddTable(reportID, "Support Reactions", numRows, numCols) |
| 156 | + |
| 157 | +' Set column headers |
| 158 | +objOpenSTAAD.Table.SetColumnHeader reportID, tableID, 1, "Node No." |
| 159 | +objOpenSTAAD.Table.SetColumnHeader reportID, tableID, 2, "FY (kN)" |
| 160 | + |
| 161 | +' Fill table with data |
| 162 | +Dim i As Long |
| 163 | +For i = 1 To numRows |
| 164 | + objOpenSTAAD.Table.SetCellValue reportID, tableID, i, 1, CStr(i + 1) |
| 165 | + objOpenSTAAD.Table.SetCellValue reportID, tableID, i, 2, CStr(i * 10) |
| 166 | +Next i |
| 167 | + |
| 168 | +End Sub |
| 169 | +``` |
| 170 | + |
| 171 | +## Run External Program from STAAD |
| 172 | +- You can use this code to run your external program directly from STAAD |
| 173 | +- If it's a Python script, convert it into an exe file and you can run it via STAAD |
| 174 | + |
| 175 | +```vb |
| 176 | +Sub Main |
| 177 | + |
| 178 | + 'Create OpenSTAAD Object |
| 179 | + Dim objOpenSTAAD As Object |
| 180 | + Set objOpenSTAAD = GetObject(, "StaadPro.OpenSTAAD") |
| 181 | + |
| 182 | + 'Check if model is open |
| 183 | + Dim stdFilePath As String |
| 184 | + objOpenSTAAD.GetSTAADFile stdFilePath, True |
| 185 | + |
| 186 | + If stdFilePath = "" Then |
| 187 | + 'Model is not open; exit sub |
| 188 | + MsgBox "No Active Model Found. Please open a STAAD model and retry.", vbExclamation, "No Active Model" |
| 189 | + Set objOpenSTAAD = Nothing |
| 190 | + Exit Sub |
| 191 | + End If |
| 192 | + |
| 193 | + 'Create Shell object |
| 194 | + Dim objShell |
| 195 | + Set objShell = CreateObject("WScript.Shell") |
| 196 | + |
| 197 | + ' Get application path |
| 198 | + Dim applicationPath |
| 199 | + applicationPath = "C:\SampleApp\Console.exe" |
| 200 | + |
| 201 | + ' Construct the command to open the STAAD model |
| 202 | + Dim command |
| 203 | + command = """" & applicationPath & """ """ & stdFilePath & """" |
| 204 | + |
| 205 | + ' Execute the command to open STAAD.Pro with the specified model |
| 206 | + objShell.Run command, 1, False |
| 207 | + |
| 208 | + ' Clean up |
| 209 | + Set objShell = Nothing |
| 210 | + Set objOpenSTAAD = Nothing |
| 211 | + |
| 212 | +End Sub |
| 213 | +``` |
| 214 | + |
| 215 | +## Conclusion |
| 216 | +- You can build small tools to assist with your regular tasks using STAAD Visual Basic script since it doesn't require any setup or admin permission |
| 217 | +- I personally prefer not to code using Visual Basic script since it's quite old, so I usually just use it to call my exe file |
| 218 | +- For large model generation or results extraction, running the script can be very slow, so my advice is to minimize STAAD while running your script to speed up execution |
| 219 | +- I'll try to keep this updated with more variations and use cases |
