Version History

Version Number Version Description


2.3.0 AutoCAD® 2018-2022 supported initial release. Update: revised to mitigate a .NET API bug with the CopyFrom() Method that results in Centroid and/or Viewport Grips that 'stick' to the previous location when non-rectangular Viewports are subsequently Moved or Copied. These grips no longer 'stick' and now behave as expected.
