Fixed Issues

General
Fixed an issued that caused the ViewCube to behave incorrectly. ALS-15473
Alias no longer crashes after selecting a preference set from the Use Preference Sets menu, and then selecting from the Workspaces menu. ALS-13620
Reopening Msave files works correctly again, even when the file location is set to a network drive. ALS-16309
Names in deletion confirm messages, such as layer names, are now only tracked if the ALIAS_TRACE level environment variable is set to a value of 4 or higher. ALS-16411
Msave now saves files to networked drives as expected. ALS-16357
Alias no longer crashes when running the Optimize For Draw plug-in. ALS-15406

Resolved a crash caused by creating a surface fillet in certain cases. ALS-15993
Copying and pasting a selection that contains a camera node no longer creates a new group in the Variant Lister. ALS-15865
Fixed an issue that caused continuity to be lost when creating a surface offset (Surfaces > Surface Offset) with Shrink to Trim turned on. ALS-15268
Copy and pasting objects between stages now includes any assigned shader or material even when Keep Shaders is turned off in the Import options (File > Import). ALS-1587
Unstitched objects (Surface Edit > Stitch > Shell Unstitch) are now assigned to the active construction layer as expected. ALS-15856
Alias no longer crashes when you use the Mesh Smooth tool with Lasso Selection Mode on to define a selection area, and then picking nothing. ALS-16003
The Profile tool no longer generates unexpected results. ALS-16304
Activating the Curve Curvature tool after creating an EP curve no longer causes Alias to deselect a curve. ALS-16018
Fixed an issue with General Preferences that caused the check boxes to not update accordingly when importing saved preferences. ALS-16030
Fixed a crash related to using the Ball Corner tool with specific data sets. ALS-16236
Changing a value in the Ball Corner Control window no longer causes Alias to crash. ALS-16308
Fixed an issue that caused a trimmed and filleted surface to be unexpectedly modified, such as when transforming the filleted surface CVs. ALS-16013
Fixed an issue that caused an attached Blend point to unexpectedly snap back to the origin of the attached Blend curve. ALS-16059

Surface fillets now build correctly when Construction Type is set to Arc (Chord). Previous to Alias 2023.1 Update, the Construction Type Arc (Chord) was called Chord. ALS-16594
Trim region cross-hairs are now larger and better positioned making them easier to see. They are also colored to indicate the selected trim region option. For example, the cross-hairs display blue for Keep, yellow for Divide, and red for Discard.

CATIA V5 export: Empty layers now get exported as expected when you enable Export Empty Layers. ALS-10712
Tolerance values set by the CATIA V5 Construction Preset in the Construction Options are now respected when you roundtrip (export then import) a CATIA V5 file. Note that Curve Fit Distance Tolerance, Trim Curve Fit, and Topology Distance still use default values. ALS-16147
