처음 보는 오류이다.

원인이 무엇인지 모르겠다.

언젠가 부터 계속 복사하여 붙여넣기를 하는데 도중에 계속 엑셀이 멈춘다.

인터넷에 찾아보니 몇가지 방법이 있다고 하는데

1. COM추가기능을 삭제한다.

내 컴퓨터에는 다음과 같은 COM 추가 기능이 설치되어 있다.

근데 체크가 되어 있지 않아 사용하지 않는 것 같은데...

하나씩 체크 해제하고 문제가 발생하는지 확

2. 하드웨어 그래칙 가속 사용 안 함. 체크

3. 잘라내기/복사/붙여넣기

콘텐츠를 붙여넣을 때 붙여넣기 옵션 단추 표시(S) 체크 해제

4. 사용자 인터페이스 옵션

Mohr's circle VBA code by ChatGPT

End Sub

To use this code, follow these steps:

1. Open your Excel workbook and press Alt+F11 to open the VBA Editor.
2. Insert a new module by clicking on "Insert" > "Module."
3. Copy and paste the code into the new module.
4. Modify the worksheet name in the line Set ws = ThisWorkbook.Sheets("Sheet1") to match your desired worksheet name.
5. Save the workbook and close the VBA Editor.
6. Press Alt+F8 to open the "Macro" dialog box.
7. Select the "CreateMohrsCircle" macro and click "Run."
8. The macro will prompt you to enter the values of sigma_x, sigma_y, and tau_xy in separate input boxes.
9. Enter the values and click "OK."
10. The Mohr's circle will be created on the specified worksheet with the entered values.

Please note that this code assumes you have a worksheet named "Sheet1" where the Mohr's circle will be created. Modify the code accordingly if you want to use a different worksheet name or if you want to adjust the layout or formatting of the circle.

Additionally, the code currently draws the Mohr's circle using text-based symbols ('•') in the worksheet. If you prefer a graphical representation, you can use VBA to create a scatter plot or utilize Excel's built-in charting features to display the circle. Let me know if you would like assistance with that aspect as well.

        ' Set chart title
        .HasTitle = True
        .ChartTitle.Text = "Mohr's Circle"
    End With
End Sub

After running the modified code, a scatter plot chart representing the Mohr's circle will be created in the specified worksheet. The chart will display the σ values on the x-axis and the τ values on the y-axis. The axis scales and titles will be set accordingly. You can adjust the chart style, axis labels, or other formatting options as desired.

Remember to modify the worksheet name in the line Set ws = ThisWorkbook.Sheets("Sheet1") to match your desired worksheet name.

VBA를 사용하여 X 축과 Y 축의 범위 값을 가져오기

ChatGPT의 답변은 다음과 같다.

Sub GetAxisRanges()
    Dim myChart As ChartObject
    Dim xAxis As Axis, yAxis As Axis
    Dim xAxisMin As Variant, xAxisMax As Variant
    Dim yAxisMin As Variant, yAxisMax As Variant
    
    ' 차트 개체 가져오기
    Set myChart = ActiveSheet.ChartObjects("Chart 1")
    
    ' X 축과 Y 축 가져오기
    Set xAxis = myChart.Chart.Axes(xlCategory)
    Set yAxis = myChart.Chart.Axes(xlValue)
    
    ' X 축 범위 가져오기
    xAxisMin = xAxis.MinimumScale
    xAxisMax = xAxis.MaximumScale
    
    ' Y 축 범위 가져오기
    yAxisMin = yAxis.MinimumScale
    yAxisMax = yAxis.MaximumScale
    
    ' 결과 출력
    MsgBox "X 축 범위: " & xAxisMin & " ~ " & xAxisMax & vbNewLine & _
           "Y 축 범위: " & yAxisMin & " ~ " & yAxisMax
