3Dsolid Mass Properties

[k005]

Hello friends;

How can I get the Total volumes of a 3Dsolid object or objects with the message box?

I bought the Quantities, but how can I get the Volumes?

Thanks in advance to the helper.

 this.Hide();
            Editor ed = aCap.DocumentManager.MdiActiveDocument.Editor;

            Adb.TypedValue[] filitre = new Adb.TypedValue[1];
            
            filitre.SetValue(new Adb.TypedValue((int)Adb.DxfCode.Start, "3DSOLID"), 0);
            SelectionFilter acSelFtr = new SelectionFilter(filitre);

            var selection = ed.GetSelection(acSelFtr);
            if (selection.Status != PromptStatus.OK)
            {
                ed.WriteMessage("\n\nKatı obje (3DSOLID) Bulunamadı.\n");
                return;
            }

            if (selection.Status == PromptStatus.OK)
            {
                SelectionSet acsset = selection.Value;
                MessageBox.Show("seçilen 3dsolid sayısı: " +
                                        acsset.Count.ToString());
            }

Thank you. How is it used in the message box?

Thank you very much. You have completed the missing piece in my work on densities-weights.
