Topic: How can I get the number of first cogopoint's number on a drawing?

[ekoneo]

I use a for cycle beginning from the first cogo points' number to last points' number.
I can calculate the last point's number adding the number of all points to first cogo point's number.
How can I get first cogopoint'number without any counting operations?

You need to look at the Command Settings. Example for next pointnumber:

Autodesk.Civil.ApplicationServices.CivilDocument CivilDoc = Autodesk.Civil.ApplicationServices.CivilApplication.ActiveDocument;
Autodesk.Civil.Settings.SettingsCmdCreatePoints CmdPointSettings = CivilDoc.Settings.GetSettings<Autodesk.Civil.Settings.SettingsCmdCreatePoints>();

int NextNumber = (int)CmdPointSettings.PointIdentity.NextPointNumber.Value;

If you get the "_All Points" PointGroup object and use the GetPointNumbers() method it returns a sequential array of all point numbers in the drawing.

Thanks Jeff_M and huiz.

Jeff_M you helped me in last week by this code about renumbering cogo points.

Code: [Select]

  public void renumpnts()

      {

          CivilDocument civdoc = CivilApplication.ActiveDocument;

          using (AcDb.Transaction tr = AcDb.HostApplicationServices.WorkingDatabase.TransactionManager.StartTransaction())

           {

               for (uint i = 1; i < 11; i++)

              {

                   if (!civdoc.CogoPoints.Contains(i))

                      continue;

                  CogoPoint pt = (CogoPoint)civdoc.CogoPoints.GetPointByPointNumber(i).GetObject(AcDb.OpenMode.ForWrite);

                   pt.Renumber(i + 100, PointNumberResolveType.Overwrite);

              }

                tr.Commit();

           }           

      }



And I add a for cycle in your code. Becouse I want to renumber all points starting from first available point to end one.

I can use it only once.. when I try to run it second time I get "Retrive attribute failed" error message.
Interestingly when I try to run second time, if I delette first point manually, it works..

my last work is:
