modify text height of AlignedDimension

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!
