general Drawing Dimension .

[Anonymous]

Hello All,

I am getting a problem for creating automatic dimension. I am done with " Retrived Dimension " and "two arc select dimension" methods.Please give me the solution of general drawing dimension so that i will try to work on it too.

                           Thank You...!!

Hello,

Here is the sample code in VBA.

This code will add General Dimensions to the straight line segments on the active drawing document.

I think you can translate this to other languages (such as C#).

Sub test()
    Dim drwDoc As DrawingDocument
    Set drwDoc = ThisApplication.ActiveDocument
    
    Dim sheet As sheet
    Set sheet = drwDoc.ActiveSheet
    
    Dim drwView As DrawingView
    Set drwView = sheet.DrawingViews(1)
    
    Dim gds As GeneralDimensions
    Set gds = sheet.DrawingDimensions.GeneralDimensions
    
    Dim dcs As DrawingCurvesEnumerator
    Set dcs = drwView.DrawingCurves
    
    Dim intentOne As GeometryIntent
    
    Dim dc As DrawingCurve
    Dim dcSegs As DrawingCurveSegments
    Dim dcSeg As DrawingCurveSegment
    
    For Each dc In dcs
        Set dcSegs = dc.Segments
        If dc.CurveType = kLineSegmentCurve And dcSegs.Count = 1 Then
            Set dcSeg = dcSegs.Item(1)
            If (Not dcSeg.StartPoint Is Nothing) And (Not dcSeg.EndPoint Is Nothing) Then
                Dim textOrigin As Point2d
                Set textOrigin = ThisApplication.TransientGeometry.CreatePoint2d
                textOrigin.X = (dcSeg.StartPoint.X + dcSeg.EndPoint.X) / 2
                textOrigin.Y = (dcSeg.StartPoint.Y + dcSeg.EndPoint.Y) / 2
                Set intentOne = drwDoc.Sheets(1).CreateGeometryIntent(dc)
                gds.AddLinear textOrigin, intentOne
            End If
        End If
    Next dc
End Sub

The result is...

Thanks for giving me the solution..Can you please give this in c#..

Thank you..

GeneralDimensions gds = oSheet.DrawingDimensions.GeneralDimensions;
DrawingCurvesEnumerator dcs = oView.DrawingCurves;

GeometryIntent intent1;

DrawingCurve dc;
DrawingCurveSegments dcSegs;
DrawingCurveSegment dcSeg;

foreach (var dc in dcs)
{
dcSegs = dc.Segments;
if (dc.CurveType == kLineSegmentCurve & dcSegs.Count == 1)
{
dcSeg = dcSegs.Item[1];
}

if ((!dcSeg.StartPoint == null) & (!dcSeg.EndPoint == null))
{
Point2d textOrigin;
textOrigin = application.TransientGeometry.CreatePoint2d();

textOrigin.X = (dcSeg.StartPoint.X + dcSeg.EndPoint.X) / 2;
textOrigin.Y = (dcSeg.StartPoint.Y + dcSeg.EndPoint.Y) / 2;
intent1 = oDrawDoc1.Sheets[1].CreateGeometryIntent(dc);
gds.AddLinear(textOrigin, intent1);
}
}

I did like this..This is giving error-------->foreach (var dc in dcs)------>dc cannot be declared in this scope because that name is used in an enclosing local scope to define a local or paramter..

DrawingView targetView = oSheet.DrawingViews[1];

GeneralDimensions gds = (GeneralDimensions) oSheet.DrawingDimensions.GeneralDimensions;
DrawingCurvesEnumerator dcs = oView.DrawingCurves;

GeometryIntent intent1 = default(GeometryIntent);
DrawingCurveSegments dcSegs = default(DrawingCurveSegments);

dcSegs = oDrawDoc1.SelectSet[1];

DrawingCurve dc = default(DrawingCurve);

DrawingCurveSegment dcSeg = default(DrawingCurveSegment);

foreach (var DrawingCurve in dcs)
{

dcSegs = dc.Segments;
if (dc.CurveType == CurveTypeEnum.kLineSegmentCurve && dcSegs.Count == 1)
{
dcSeg = (DrawingCurveSegment)dcSegs[1];
}

if (!(dcSeg.StartPoint == null) && (!(dcSeg.EndPoint == null)))
{
Point2d textOrigin;
textOrigin = application.TransientGeometry.CreatePoint2d();

textOrigin.X = (dcSeg.StartPoint.X + dcSeg.EndPoint.X) / 2;
textOrigin.Y = (dcSeg.StartPoint.Y + dcSeg.EndPoint.Y) / 2;
intent1 = oDrawDoc1.Sheets[1].CreateGeometryIntent(dc);
gds.AddLinear(textOrigin, intent1);
}
}

------ I draw the code like this...there is no error but its not working     ---->

foreach (var DrawingCurve in dcs)
{

dcSegs = dc.Segments;

Hello,

Here is the code that has been rewritten in C#.

try
{
    if (!(application.ActiveEditDocument is DrawingDocument oDrawDoc1))
    {
        return;
    }
    Sheet targetSheet = oDrawDoc1.ActiveSheet;
    if (targetSheet == null || targetSheet.DrawingViews.Count == 0)
    {
        return;
    }
    DrawingView targetView = targetSheet.DrawingViews[1];

    foreach (DrawingCurve drawingCurve in targetView.DrawingCurves)
    {
        DrawingCurveSegments drawingCureveSegments = drawingCurve.Segments;
        if (drawingCurve.CurveType == CurveTypeEnum.kLineSegmentCurve && drawingCureveSegments.Count == 1)
        {
            DrawingCurveSegment drawingCurveSegment = drawingCureveSegments[1];
            if (drawingCurveSegment.StartPoint != null && drawingCurveSegment.EndPoint != null)
            {
                Point2d textOrigin = application.TransientGeometry.CreatePoint2d();

                textOrigin.X = (drawingCurveSegment.StartPoint.X + drawingCurveSegment.EndPoint.X) / 2;
                textOrigin.Y = (drawingCurveSegment.StartPoint.Y + drawingCurveSegment.EndPoint.Y) / 2;
                GeometryIntent intentOne = targetSheet.CreateGeometryIntent(drawingCurve);
                targetSheet.DrawingDimensions.GeneralDimensions.AddLinear(textOrigin, intentOne);
            }
        }
    }
}
catch (Exception ex)
{
    MessageBox.Show(ex.ToString());
}

Hacking APIs is easier in VBA than C#.

How about using VBA to explore APIs?

I always understand how the APIs work in VBA well and then write AddIn codes in C#.

Hacking the APIs in C#(or VB.net) requires much effort than in VBA because we must restart Inventor when the code is changed.

Thank you for taking the time to help me out. Sorry I forgot to mention it but I am completely new to api and so far my experience have been to get codes from forums/help file then modify them to fit my need. I did try to build upon the example you provided me but I couldn’t get anywhere after researching for a while. Attached is what I did based on your suggestion not sure if I even did that right, could you build upon it when you get the chance.

Sincerely,
