Annotative Mtext
« on: October 29, 2012, 12:59:25 PM »
If you are adding MText from an Annotative style is this the way you have to calculate text height?
Code - C#: [Select]
  1. mtxt.TextHeight = (1.0 / Db.Cannoscale.Scale) * txtStyleTblRecord.TextSize;
  2.  
Testing code
Code - C#: [Select]
  1.  
  2.          [CommandMethod("MTL")]
  3.         public void MTL()
  4.         {
  5.             MtxtCommand(AttachmentPoint.TopLeft);
  6.         }
  7.         [CommandMethod("MTC")]
  8.         public void MTC()
  9.         {
  10.             MtxtCommand(AttachmentPoint.TopCenter);
  11.         }
  12.         [CommandMethod("MTR")]
  13.         public void MTR()
  14.         {
  15.             MtxtCommand(AttachmentPoint.TopRight);

Looks like SetFromStyle() will make annotative and add annotation scale
