Hello every body,

I just want to make a linear dimension vertical or horizontal with 2 point.

I try to make command but it not work.

Hi,

I'm not sure to understand what you're trying to achieve, but you should be able to get some inspiration from the following codes.

[CommandMethod("DHOR")] public static void DimHorizontal() { var doc = Application.DocumentManager.MdiActiveDocument; var db = doc.Database; var ed = doc.Editor; // get the first point var options = new PromptPointOptions("\nPick the first point: "); var result = ed.GetPoint(options); if (result.Status != PromptStatus.OK) return; var pt1 = result.Value; // get the second point (must have a different X value) options.Message = "\nPick the second point: "; options.BasePoint = pt1; options.UseBasePoint = true; while (true) { result = ed.GetPoint(options); if (result.Status != PromptStatus.OK) return; if (result.Value.X != pt1.X) break; ; ed.WriteMessage("\nSecond point must have different X value."); } var pt2 = result.Value; using (var tr = db.TransactionManager.StartTransaction()) { // compute the 'dimensionLinePoint' (max Y value + the current dimstyle text height X 5 var dimstyle = (DimStyleTableRecord)tr.GetObject(db.Dimstyle, OpenMode.ForRead); var pt3 = new Point3d(pt1.X, Math.Max(pt1.Y, pt2.Y) + 5 * dimstyle.Dimtxt, 0.0); // create a new RotatedDimension var cSpace = (BlockTableRecord)tr.GetObject(db.CurrentSpaceId, OpenMode.ForWrite); var dim = new RotatedDimension(0.0, pt1, pt2, pt3, "", db.Dimstyle); dim.TransformBy(ed.CurrentUserCoordinateSystem); cSpace.AppendEntity(dim); tr.AddNewlyCreatedDBObject(dim, true); tr.Commit(); } } [CommandMethod("DVER")] public static void DimVertical() { var doc = Application.DocumentManager.MdiActiveDocument; var db = doc.Database; var ed = doc.Editor; // get the first point var options = new PromptPointOptions("\nPick the first point: "); var result = ed.GetPoint(options); if (result.Status != PromptStatus.OK) return; var pt1 = result.Value; // get the second point (must have a different Y value) options.Message = "\nPick the second point: "; options.BasePoint = pt1; options.UseBasePoint = true; while (true) { result = ed.GetPoint(options); if (result.Status != PromptStatus.OK) return; if (result.Value.Y != pt1.Y) break; ; ed.WriteMessage("\nSecond point must have different Y value."); } var pt2 = result.Value; using (var tr = db.TransactionManager.StartTransaction()) { // compute the 'dimensionLinePoint' (max X value + the current dimstyle text height X 5 var dimstyle = (DimStyleTableRecord)tr.GetObject(db.Dimstyle, OpenMode.ForRead); var pt3 = new Point3d(Math.Max(pt1.X, pt2.X) + 5 * dimstyle.Dimtxt, pt1.Y, 0.0); // create a new RotatedDimension var cSpace = (BlockTableRecord)tr.GetObject(db.CurrentSpaceId, OpenMode.ForWrite); var dim = new RotatedDimension(0.5 * Math.PI, pt1, pt2, pt3, "", db.Dimstyle); dim.TransformBy(ed.CurrentUserCoordinateSystem); cSpace.AppendEntity(dim); tr.AddNewlyCreatedDBObject(dim, true); tr.Commit(); } }

Hi,

I want to measure a 3D object, i have not been able to create dimensions in the views (Front, Left...) ,all dimensions are oriented in top view.

Can you help me with this?

Thanks

You have to set the Dimension.Normal property.

Vector3d.ZAxis for Top view (default)

-Vector3d.YAxis for Front view

-Vector3d.XAxis for Left view
