Title: acedXformSS()
Post by: Bobby C. Jones on June 29, 2006, 08:57:38 AM

Does the 2007 version of the managed API wrap this function anywhere?  I couldn't find anything last night and have rolled my own version, but considering that they wrapped acedDragGen() it seems at least somewhat likely that acedXformSS() is out there, somewhere...

I am tired and an EXTREMELY quick look resulted in this:

Autodesk.AutoCAD.EditorInput.DragCallback MethodsInvoke
Autodesk.AutoCAD.EditorInput.SamplerStatus

Invoke(

Autodesk.AutoCAD.Geometry.Point3d current,

Autodesk.AutoCAD.Geometry.Matrix3d& xform)

Parameters
current Input Autodesk.AutoCAD.Geometry.Point3d object. 
xform Input Autodesk.AutoCAD.Geometry.Matrix3d& object. 

Return Type
Autodesk.AutoCAD.EditorInput.SamplerStatus


No idea if this is what you are after Bobby, but I am off to la la land...night.

Cheers,
Glenn.

Hey Glenn,
Thanks for taking a look at this.  Have a good rest!

That's a related topic, and I was able to create a DragCallback delegate, but it's not quite what I was looking for.

I am re-visiting the 2006 code from here http://www.theswamp.org/index.php?topic=8198.0, which drags selected entities around the cursor and copies them to a new location, mimicking the COPY command (I never did get all the bugs worked out).  Now in '07 they have wrapped acedDragGen() and made it all a moot point.  However, I wasn't able to find where, or if, they wrapped acedXformSS().  I banged out a quick version late last night, but I don't want to pursue it any further if it's provided in the API.

Code: [Select]

    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();
      }
    }
