drag.zip

Hallo,

bin auf der Suche nach einer Lösung einen Auswahlsatz zu "draggen".
Im Beispiel das Draggen für ein Entity. Aber wie funktioniert es für einen Auswahlsatz?

Gruss
Peter

Servus Peter,
hatte gerade das selbe Problem, hier ein Beispiel von TheSwamp.

Code:

---

using System;
using System.Collections;
using System.Collections.Generic;

using Autodesk.AutoCAD.EditorInput;
using Autodesk.AutoCAD.Geometry;
using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.AutoCAD.GraphicsInterface;
using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.Runtime;

using RSNNAcadApp.ExtendedCommands;

[assembly: CommandClass(typeof(RSNNAcadApp.ExtendedCommands.EntityDragger))]
namespace RSNNAcadApp.ExtendedCommands
{

    public class EntityDragger
    {
        private Point3d m_basePoint;

        [CommandMethod("dragSS")]
        public void SsDragger()
        {
            Editor currentEditor = Application.DocumentManager.MdiActiveDocument.Editor;

            //Create a new selection set options object
            PromptSelectionOptions ssOptions = new PromptSelectionOptions();
            ssOptions.AllowDuplicates = true;
            ssOptions.MessageForAdding = "Select objects to copy: ";

            //Get a selection from the user
            PromptSelectionResult ssResult = currentEditor.GetSelection(ssOptions);
            if (ssResult.Status != PromptStatus.OK)
            {
                return;
            }

            //Get a base point from the user
            PromptPointResult pointResult = currentEditor.GetPoint("\nSelect base point: ");
            if (pointResult.Status != PromptStatus.OK)
            {
                return;
            }
            m_basePoint = pointResult.Value;

            //Initiate the drag callback delegate
            DragCallback dragCallbackDelegate = this.FollowCursor;

            //Start the drag operation
            PromptDragOptions dragOptions = new PromptDragOptions(ssResult.Value, "\nSelect destination point: ", dragCallbackDelegate);

            PromptPointResult destinationPointResult = currentEditor.Drag(dragOptions);
            if (destinationPointResult.Status != PromptStatus.OK)
            {
                return;
            }

            //Determine the final displacement matrix
            Matrix3d transMat = Matrix3d.Displacement(m_basePoint.GetVectorTo(destinationPointResult.Value));

            //transform the ss to the new location
            this.TransformSelectionSet(ssResult.Value, transMat);
        }

        //DragCallback Delegate
        public SamplerStatus FollowCursor(Point3d currentPoint, ref Matrix3d transMat)
        {
            //transMat = Matrix3d.Scaling(2, currentPoint);
            //transMat *= Matrix3d.Displacement(m_basePoint.GetVectorTo(currentPoint));
            transMat = Matrix3d.Displacement(m_basePoint.GetVectorTo(currentPoint));

            return SamplerStatus.OK;
        }

        private void TransformSelectionSet(SelectionSet ss, Matrix3d transMat)
        {
            if (ss.Count == 0)
            {
                return;
            }

            Database targetDatabase = ss[0].ObjectId.Database;

            using (Transaction trans = targetDatabase.TransactionManager.StartTransaction())
            {
                BlockTableRecord currentSpace = (BlockTableRecord)trans.GetObject(targetDatabase.CurrentSpaceId, OpenMode.ForWrite);

                foreach (SelectedObject selectedObj in ss)
                {
                    Entity selectedEntity = (Entity)trans.GetObject(selectedObj.ObjectId, OpenMode.ForRead);

                    Entity transformedEntity = selectedEntity.GetTransformedCopy(transMat);

                    currentSpace.AppendEntity(transformedEntity);

                    trans.AddNewlyCreatedDBObject(transformedEntity, true);
                }

                trans.Commit();
            }
        }

    }
   
}

Ich denke das sollte helfen
