Hi! this might be pretty basic but I just can't find the way to do it. I'm trying to modify the text height of an AlignedDimension via C#.
In AutoCAD, I can modify it in the properties panel:
below is my code for aligned dimension creation :
using Autodesk.AutoCAD.EditorInput;
using Autodesk.AutoCAD.DatabaseServices;
ObjectId drawAlignedDimension(Point3d line1Point, Point3d line2Point, Point3d dimLinePoint, string text)
{
Document document = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;
Editor editor = document.Editor;
Database database = document.Database;
ObjectId dimensionObjId = ObjectId.Null;
using (var tr = database.TransactionManager.StartTransaction())
{
DimStyleTable dimStyleTbl = database.DimStyleTableId.GetObject(OpenMode.ForRead) as DimStyleTable;
DimStyleTableRecord targetDimStyle = null;
const string targetDimStyleName = "ISO-25";
//find dimStyle
foreach (ObjectId objId in dimStyleTbl)
{
DimStyleTableRecord dimStyleRec = objId.GetObject(OpenMode.ForRead) as DimStyleTableRecord;
if (dimStyleRec.Name == targetDimStyleName)
{
targetDimStyle = dimStyleRec;
break;
}
}
//create dimension
using (var dimension = new AlignedDimension(line1Point, line2Point, dimLinePoint, text, targetDimStyle.Id))
{
var blkTbl = database.BlockTableId.GetObject(OpenMode.ForRead) as BlockTable;
var modelSpace = blkTbl[BlockTableRecord.ModelSpace].GetObject(OpenMode.ForWrite) as BlockTableRecord;
dimensionObjId = modelSpace.AppendEntity(dimension);
tr.AddNewlyCreatedDBObject(dimension, true);
}
tr.Commit();
}
return dimensionObjId;
}
ObjectId dimId = drawAlignedDimension(new Point3d(0, 0, 0), new Point3d(30, 0, 0), new Point3d(5, 5, 0), "test text");
I've been searching and reading the document for several days but seem not able to find relative source or property. Can someone give me some suggestions? Any help is really appreciated!
