Known Issues

Beta Version 1.2.7

Contains fixes for the known issues relating to versions 1.2.6.

Known Issues:

If a .fsn file contains sweep data, basic and rbf surfaces, saving the file in Delta can change the orientation of the current surface with respect to the other surfaces. If this happens reloading the file into FastSCAN and changing from the current surface to one of the other surfaces changes he orientation of the surface on the screen.
If an absolute volume has been created and is displayed when the Volumes tab is selected, it is still visible in Sections and Contours modes.

Beta Version 1.2.6

Contains fixes for the known issues relating to versions 1.2.4, 1.2.4B and 1.2.5.

Known Issues:

Performing a registration with only a subset of landmarks selected causes the registration to fail.

Beta Versions 1.2.4, 1.2.4B and 1.2.5

Known Issues:

Pressing 'set axis' in Section mode after performing a registration introduces an offset or reverts the scans back to their pre-registration positions. Saving the subject scan after registration and before pressing 'set axis' in Section mode solves this problem.
Demo files provided with the installation of Delta can not be reloaded once they have been saved.
