Get the Primary Load Case Information

Learn to obtain the primary load case information from the STAAD.Pro main application.

1. Continue with the model from the previous exercise.

2. Enter the following functions to define the primary load case variables:

DimiAs Integer

DimLCaseCountAs Integer

DimLCaseNum()As Long

DimLCaseName()As String

3. Enter the following functions to retrieve the Primary Load Case Information from the active STAAD.Pro model:

LCaseCount = objSTAADGUI.Load.GetPrimaryLoadCaseCount()

ReDimLCaseNum(LCaseCount)

ReDimLCaseName(LCaseCount)

objSTAADGUI.Load.GetPrimaryLoadCaseNumbersLCaseNum

For i = 0 ToLCaseCount-1

LCaseName(i) = CStr(LCaseNum(i)) & : & objSTAADGUI.Load.GetLoadCaseTitle(LCaseNum(i))

Note: In this exercise, we will create the following user dialog to select a defined load case:

2. Click on the Edit User Dialogicon.

3. Double-click anywhere within the new dialog in the UserDialog Editor.

4. Enter the following information into the Edit UserDialog Propertiesdialog:

Caption: Select Load Case

Then, click on the double right arrowbutton to enter the name of the dialog box.

5. Click on the Add Text icon in the UserDialogEditor. Click within the new dialog to define the text box location and then double-click withinthe new text box.

6. Enter the following information into the Edit Text Propertiesdialog:

Caption: Load Case:

Quoted: (checked)

Click on the double right arrowbutton to enter the name of the field. Then, click Close.

7. Click on the Add List Boxicon in the UserDialog Editor. Click within the new dialog to define the list box location and then double-clickwithin the new list box.

8. Enter the following information into the Edit List Box Propertiesdialog:

Array: LCaseName

Click on the double right arrowbutton to enter the name of the field. Then, click Close.

9. Click on the Add OK Buttonicon in the New UserDialog Editor. Then, click within the new dialog to define the OK button.

10. Click on the Add Cancel Buttonicon in the New UserDialog Editor. Then, click within the new dialog to define the Cancel button.

11. Click on the Save and Editicon in the New UserDialog Editor.

12. Delete the last line of this code (Dialog dlg).




Obtain the Selected Load Case Results

Learn to define the variables that were used in the Select Load Case dialog.


2. Enter the following functions to define the input variables:

DimdlgResultAs Integer

dlgResult = Dialog(dlg)

IfdlgResult = -1 Then

DimLoadCaseAs Long

DimLoadCaseNameAs String

LoadCase = LCaseNum(dlg.ListBox1)

LoadCaseName = LCaseName(dlg.ListBox1)

3. Enter the following functions to instruct STAAD.Pro to cancel the operation of the Cancelbutton was clicked:

ElseIfdlgResult = 0 Then

Debug.Print Cancel button PressedEnd If




Get the Selected Node Information

Learn to obtain the selected node information from the STAAD.Pro main application.


2. Enter the following functions to determine if any nodes have been selected in the main application:

DimNumSelNodesAs Long

DimSelNodeArray()As Long

NumSelNodes = objSTAADGUI.Geometry.GetNoOfSelectedNodes()

IfNumSelNodes > 0 Then

ReDimSelNodeArray(NumSelNodes)

objSTAADGUI.Geometry.GetSelectedNodes(SelNodeArray, 1)

Else

MsgBoxPlease Select Nodes, vbOKOnly

Exit Sub

End If

3. Enter the following functions to get the nodal displacements for the selected nodes:

DimjAs Integer

DimNodeNoAs Long

DimDisplArray(6)As Double

DimMaxDisplArray(6)As Double

DimNodeArray(6)As String

Fori = 0 ToNumSelNodes-1

NodeNo = SelNodeArray(i)

objSTAADGUI.Output.GetNodeDisplacements(NodeNo, LoadCase, DisplArray())

Forj = 0 To5

If Abs(DisplArray(j)) >Abs(MaxDisplArray(j)) Then

MaxDisplArray(j) = Round(DisplArray(j), 3)

NodeArray(j) = N & CStr(NodeNo)

End If

Nextj

Retrieve the Base Units Configuration

Learn to retrieve the base units configuration that has been specified in the main application.


2. Enter the following functions to determine the base units configuration that were specified in the STAAD.Pro Start Page.

DimBaseUnitAs Integer

BaseUnit = objSTAADGUI.GetBaseUnit

IfBaseUnit = 1 Then

BaseLengthUnit = in

Else

BaseLengthUnit = m

End If

Return the Maximum Deflection Results

Learn to obtain the maximum deflection results for the selected nodes and the selected load case.


Note: In this exercise, we will create the following user dialog to display the maximum deflection of the selected nodes:

2. Click on the Edit User Dialogicon.

3. Double-click anywhere within the new dialog in the UserDialog Editor.

4. Enter the following information into the Edit UserDialog Propertiesdialog:

Caption: Maximum Deflection

Then, click on the double right arrowbutton to enter the name of the dialog box.

5. Use the Add Texttool to add the following text fields to the dialog:

Load Case:

X:

Y:

Z:

Note: Ensure that the Quotedfield is selected when defining the text fields.

6. Use the Add Texttool to add the following text fields to the dialog:

LoadCaseName

CStr(MaxDisplArray(0))



BaseLengthUnit

NodeArray(0)

NodeArray(1)

NodeArray(2)

Note: Ensure that the Quotedfield is not selected and the Fieldparameter is left blank when defining the text fields for the variables.

7. Click on the Add OK Buttonicon in the New UserDialog Editor. Then, click within the new dialog to define the OK button.

8. Click on the Save and Editicon in the New UserDialog Editor.

9. Redefine the User Dialog by changing the last two lines in the macro to the following:
