Revision History

The following notes describe changes, fixes and enhancements to 3DVU. Where version numbers are skipped it is normally due to the fact that the version never left the development area.

2.13 [07/11/2011]

The boolean engine used by 3DVU was occasionally generating illegal polygons. When these were passed to the 3D rendering engine the engine incorrectly computed the extents of the polygon with the result that the desired data was extremely small compared to this bad polygon. This has been fixed.

2.11 [01/10/2011]

The progress bar is now visible when 3Di files are opened by double-clicking or by being launched from a shell within another application.

2.10 [03/10/2010]

Added support for 3Di v1.7 which includes support for paths with different endcaps: round, flush and 1/2 width extended.

2.09 [02/23/2010]

Modified the size of some dialogs based on changes in Windows 7.

2.08 [02/10/2010]

Added the X, Y, Z co-ordinate of the current mouse position to the status bar.

2.07 [01/05/2010]

Modified the 3D-VU installer.

Improved complex solid rendering using internal boolean operations.

2.05 [03/11/2009]

Added support for AWROut special entities and tables.

3DVU V2.04 02/05/09

A new element has been added to the 3Di database - a path with constant width. 3DVU 2.04 supports this new element. The element was added for use with simulation tools that prefer to use paths when possible instead of the previous conversion of each path to a boundary.

3DVU V2.02 05/20/08

Added an option to toggle the 3D axes symbol on/off. (this can be useful if you don' want them showing during snapshots.)

Windows size and placement is now stored/restored in a new way which should be more stable. Previous versions sometimes corrupted the window position resulting in full screen only sizing.

DRC functionality is now licensed separately - this enable us to offer a lower cost basic viewer without the 3D DRC.
