Topic: Switching back to the original view after creating a UCS.

[tik]

I am creating a new UCS and aligning it to the line that user picks in the drawing. For picking the line I am setting the coordinate system to be WCS and after picking the link I am creating a new UCS and setting it to current.

For example if the user picks the line in the SW Isometric View, I see that my command is creating the new UCS and setting it to current but instead of going back to SW Isometric View it is setting to Top View.

What do I need to do to set it back to the original view.

Thanks in advance.

Following is the code I am using to Create the UCS and Make it current and I am not doing any thing to change the views.

Code - C#: [Select]

1. public static void CreateUCS(string ucsName, double[] origin, double[] xAxis, double[] yAxis, bool makeCurrent)
2.         {
3.             // Get the current document and database, and start a transaction
4.             Document acDoc = AQME_ACAD.AQMEACADInstance.ActiveDocument;
5.             Database acCurDb = acDoc.Database;
6.             using (Transaction acTrans = acCurDb.TransactionManager.StartTransaction())
7.             {
8.                 using (DocumentLock dl = AQME_ACAD.AQMEACADInstance.ActiveDocument.LockDocument())
9.                 {
10.                     // Open the UCS table for read
11.                     UcsTable acUCSTbl;
12.                     acUCSTbl = acTrans.GetObject(acCurDb.UcsTableId, OpenMode.ForWrite) as UcsTable;
13.                     UcsTableRecord acUCSTblRec;
14.                     // Check to see if the ucsName UCS table record exists
15.                     if (acUCSTbl.Has(ucsName) == false)
16.                     {
17.                         acUCSTblRec = new UcsTableRecord();
18.                         acUCSTblRec.Name = ucsName;
19.                         acUCSTbl.Add(acUCSTblRec);
20.                         acTrans.AddNewlyCreatedDBObject(acUCSTblRec, true);
21.                     }
22.                     else
23.                     {
24.                         acUCSTblRec = acTrans.GetObject(acUCSTbl[ucsName], OpenMode.ForWrite) as UcsTableRecord;
25.                     }
26.                     acUCSTblRec.Origin = new Point3d(origin);
27.                     //calulate vector between two points
28.                     Point3d origin1 = new Point3d(origin);
29.                     Point3d xPoint = new Point3d(xAxis);
30.                     Point3d yPoint = new Point3d(yAxis);
31.  
32.                     Vector3d vectx = origin1.GetVectorTo(xPoint);
33.                     Vector3d vecty = origin1.GetVectorTo(yPoint);
34.  
35.                     acUCSTblRec.XAxis = vectx;
36.                     acUCSTblRec.YAxis = vecty;
37.                     acTrans.Commit();
38.                 }
39.             }
40.  
41.             if (makeCurrent == true)
42.             {
43.                 using (Transaction acTrans = acCurDb.TransactionManager.StartTransaction())
44.                 {
45.                     using (DocumentLock dl = AQME_ACAD.AQMEACADInstance.ActiveDocument.LockDocument())

53.                         {
54.                             acUCSTblRec = acTrans.GetObject(acUCSTbl[ucsName], OpenMode.ForWrite) as UcsTableRecord;
55.                             // call the set tolerances method to set the tolerances.                        
56.                             // Open the active viewport
57.                              ViewportTableRecord acVportTblRec;

60.                                 acVportTblRec.IconAtOrigin = true;
61.                                 acVportTblRec.IconEnabled = true;
62.                                 // Set the UCS current
63.                                 acVportTblRec.SetUcs(acUCSTblRec.ObjectId);
64.                                 acDoc.Editor.UpdateTiledViewportsFromDatabase();
65.                                 acTrans.Commit();

Before code
    ViewTableRecord CurrentVtr = ed.GetCurrentView();

end of code
acDoc.Editor.SetCurrentView(CurrentVtr);

[MexicanCustard]

This also works:

Code: [Select]

Matrix3d olducs = ed.CurrentUserCoordinateSystem;

......

ed.CurrentUserCoordinateSystem = olducs;

Bryco, MexicanCustard,

Thanks for the suggestions. I will give them a try.

Can you satisfy my curiosity please ?

What is
AQME_ACAD
and
AQME_ACAD.AQMEACADInstance

Hi Kerry,

AQME_ACAD is a wrapper class I wrote for the CAD Interactions, I want to have singleton object for my CAD interactions.
