Resetting Z Point coordinates

[k005]

Hello friends;

I want to set the Z values ​​of all objects in the drawing to 0. But I think there is an error somewhere in this code. It does not give 0 to Z values.

Thanks in advance to the helpful friend.

 private void btnMesleki_Click(object sender, EventArgs e)
        {
            this.Close();
                // Aktif belgeyi al
            Aapp.Document doc = aCap.DocumentManager.MdiActiveDocument;
            Database db = doc.Database;
            Editor ed = doc.Editor;

            // Kullanıcıdan nesneleri seçmesini iste
            PromptSelectionResult selRes = ed.GetSelection();
            if (selRes.Status != PromptStatus.OK)
            {
                ed.WriteMessage("Seçim iptal edildi veya hatalı.");
                return;
            }

            // Seçilen nesneleri al
            using (Transaction trans = db.TransactionManager.StartTransaction())
            using (Aapp.DocumentLock docLock = Adoc.LockDocument())
            {
                SelectionSet selSet = selRes.Value;
                foreach (ObjectId objId in selSet.GetObjectIds())
                {
                    Entity ent = trans.GetObject(objId, Adb.OpenMode.ForWrite) as Entity;

                    if (ent != null)
                    {
                        // Z koordinatını sıfırla
                        ent.TransformBy(Matrix3d.Displacement(new Vector3d(0, 0, -ent.GeometricExtents.MinPoint.Z)));
                    }
                }

                // İşlemleri tamamla
                trans.Commit();
            }

            // Ekrana yazı bas
            ed.WriteMessage("Seçilen nesnelerin Z koordinatları sıfırlandı.");
        }

How do we integrate it into the code I gave above?

[ActivistInvestor]

It is an extension method. You just add it to your code file and then call it like it was a method of the Entity class.

<snip>
Entity ent = trans.GetObject(objId, Adb.OpenMode.ForWrite) as Entity;

if (ent != null)
{
   // Z koordinatini sifirla
   ent.TranslateToXYPlane();
}

It's busy... I'll try. Thank you.

Cannot be accessed due to protection level. I'm getting the error.

AcRx means Autodesk.AutoCAD.Runtime

[k005]

Ok. Solution?

@k005 

The immediate solution is attached.
The long term solution is to study.

Thank you. I didn't notice...

* Isn't there a much shorter ready-made code?

It will only give zero value to the Z points of 2D objects. will reset.

Thanks.

Perhaps have a look at this:

You really need to provide more information about your problems.

happy new year

The code that I posted will only move objects so that the bottom of their bounding box is in the XY plane.

That makes the assumption that they are 2 dimensional objects that are parallel to the XY plane. If that's not the case then you need to be more specific about exactly what it is you are trying to do and what types of objects you are dealing with.

[k005]

What I want to do is to set the Z point value of objects such as Line, polyline, circle, mline, Text, Mtext to zero. If it's already zero, it won't do anything.

for example a Line object. 500 units and at an angle of 14 degrees. Z1: 18 ,Z2: 35 change it to Z1: 0 , Z2: 0...

[k005]

I added the class here. In the file I added below, it resets the Z value of only Circle objects. Other Line objects do not reset.

* I tried it in text and points. They also reset. OK.

Hi,

For curves that aren't parallel to the XY plane, you can try the Curve.GetOrthoProjectedCurve method.

OK, let me investigate. Thank you.
