Improvements
Added the ability to use Ctrl+F on grid layers, so they can be quickly located in the file explorer.
Added support for loading routes from disk, improving persistence and reuse of routes.
Bugs
Fixed a crash when using the Quick Profile, Ctrl+clicking the same location.
Fixed unnecessary reshading of the dynamic grid on load.
Fixed an issue where multi‑layer grids did not shade all layers when loaded (only the first layer was shaded).
Corrected
cmdop surfacediffso it no longer incorrectly forces use of a layer ID parameter.Fixed Extract Area on multi‑layer grids that previously produced an incorrect (height) grid.
Fixed an issue using Scalar Copy and Attach to Grid operations so scalars are properly named, and added or replaced on the target grid.
Fixed an issue where cable/pipe objects did not adjust to vertical exaggeration changes. They now visually scale with the rest of the scene.
Fixed an issue where BAG file imports could result in missing data.
Fixed an issue when importing XYZ files where the first 3 columns were not always XYZ.
Fixed an issue where 2 vertical CRS with the same EPSG code but slightly different wkt strings were treated as different.
Known Issues
Issue | Summary | Affects Version/s | Expected Fix Version |
|---|---|---|---|
License Manager - Activate Softlock | Licensing - Opening older versions of Qimera may deactivate your license There is a known issue with licensing in older versions of Qimera. An error would appear in the dialog “Failed to Activate License” with the message “There are network adapters on the system that are disabled, please enable them and try again.” when trying to activate the softlock license. In order to fix this issue, we’ve updated the licensing in Qimera 2.8.0 and License Manager 1.10.2. This update may cause accidental license deactivation if you activate your license in Qimera 2.8.0 and then open an earlier 2.7.x version. The fix is to manually copy the DLLs (found in the link below) into that older version’s installation folder as noted in steps 1 and 2:
