The previous version contained smaller but significant changes and I warned their could have been some introduced errors. Unfortunately, this did occur and Version 1.5.2.2 largely contains bug fixes and extended DXF support.
New functionality
DXF support now includes more entities - text is not yet supported, but will be added soon.
Changes
New expiry date extended to 1 October 2014.
Bug fixes
The camera occasionally rotated unexpectedly in plan view.
Mapping in the scene did not always show the poles in the correct locations on the stereo-net.
Selecting scene meshes in Clipping Mode did not always highlight the correct layers in the grid.
Various coding changes to enable and simplify future additions.
Thanks for the e-mail feedback on the errors, and apologies for the slow response time to correct - I was travelling and also have slightly too much on my plate at the moment :)
