Fixed Issues

Modeling
Fixed an issue that caused surface fillets to disappear after adding more input surfaces in certain cases.
In the Duplicate Object Control window, pressing Tab now moves to the next input field as expected. ALS-15572
Fixed an issue that caused fillets created as chained fillets to fail edge criteria in some cases. ALS-7946
The 3D-Trimming option in the Trim tool has been reverted to its behavior prior to Alias 2023. ALS-5288
Fixed an issue that caused bounding box sizes on some input geometry to be inaccurate. ALS-13071
The Curve Curvature locator no longer changes the Max/Min Radius values after switching the camera from perspective view to orthographic view for imported IGS circle geometry. ALS-5977, ALSO-6064.
You can now access the Degree and Spans options in the Control Panel to edit point and blend curves as expected. ALS-5545
Resolved an issue with Blend Curves that caused history updates to fail. ALSO-7048
Resolved a crash caused by using the Subdiv Insert Edge tool to insert perpendicular edges (Insert Mode set to Perpendicular) in certain cases. ALSO-5788
Fixed an issue with the Surface Fillet tool that caused all created fillet surfaces to be deleted after deselecting one fillet input surface when the Query Edit tool is active. ALS-17029
After query editing a fillet result, you can now add or remove input surfaces again without issues. ALSO-5771
Fixed an issue that caused some tools, including Freeform Blend, Draft, and Rolled Edge, to not properly work with trimmed edges in specific cases. Correct edge alignment is now possible. ALSO-4792
The Create Trim option in the Surface Offset tool no longer generates incorrect trim curves. ALSO-5664
Layers now display as active in the Layer Bar after they are created. ALSO-7854
Fixed an issue that caused subdiv object trimming results to be different based on how the object was created. ALS-15785
New blend curves now get created with improved shape optimization and spiral shapes are no longer unexpectedly generated. ALSO-4790
Performing Zero Transforms on grouped objects created on a construction plane no longer deletes construction history. ALSO-4650
Resolved a crash related to moving the Dynamic Section tool manipulator. ALSO-4796
Degree and Spans information now displays in the Control Panel when creating an Edit Point Curve. ALS-17080
When subdivision modeling, the warning that construction history is to be deleted now only displays if the subdivision operation modifies input data, such as on an active objective with construction history. ALS-4753
Geometric normals no longer get inverted when mirroring geometry across a center line using Edit > Duplicate > Mirror. ALSO-6631
Fixed an issue that caused a surface to be unexpectedly duplicated when undoing a CV transformation done by the Transform CV tool. This only happens in very specific situations. ALSO-4747


Performance
Performance is no longer affected when working with the Information Window open. ALSO-4795
Resolved Duplicate Object performance issues. ALS-16842


Data Transfer
You can now import .edf files into Alias as expected. ALSO-5182
Resolved NX file import issue. Alias now supports reading of NX 2212 series files. ALS-17076
Importing CATIA V5 files with Materials/Fill Colors set to Fill Colors to HW Shaders and with Convert Curves and Convert Nurbs turned on, now only creates shaders for object fill colors as expected. ALSO-5103
Fixed a CATIA V5 export issue that caused invisible objects to be translated to visible objects despite Export Invisible being on in the Export Options. ALSO-4779, ALSO-4795
Turning on Tessellate in the FBX Save As options now generates tessellation data for surfaces as expected. ALS-17150, ALSO-4749
When Assign Shaders to Geom. Sets Only is on, all of the assigned Alias hardware shaders are now translated to CATIA V5 materials regardless of other export settings. ALSO-4734
The CATIA 5 and PTC Granite exporters now use the most recent version of the Autodesk Translation Framework (ATF). You can still use the legacy-based versions of these exporters by setting the following environment variables:
ALIAS_CATIA5_EXPORT_ATF to either 0 or false
ALIAS_GRANITE_EXPORT_ATF to either 0 or false.


Dynamo
The Dynamo Surface.FlipNormalDirection node now works as expected. ALSO-4762
Resolved an issued that caused spheres created and trimmed in Dynamo to be untrimmed when sent to Alias. AlSO-5205
The Dynamo Curve.Reverse node now works as expected. ALSO-4766
The Dynamo Node Surface.ToNurbsSurface now has an additional boolean input option named limitSurface. When you set it to false, trimmed surfaces are no longer reduced to their minimal active region. ALSO-4798, ALSO-5311
Dynamo Player scripts with option dropdown lists no longer unexpectedly refresh results when the dropdown is opened and closed, even if the value hasn't been changed. ALS-16875


Known Issues

  • Deleting Shader directories - Using the Delete option from the Shader Library context menu may remove shader directories that are not currently selected.

    Workaround: If you want to remove library directories from the Shader Library, either click the Delete icon in the Shader Library icon bar or click the X icon. These options remove the library directory from the Shader Library, but the shader and environment files are not permanently deleted from you system.

    You can also select Show in Explorer to perform your operations in Windows Explorer.

  • When using the Turnable option from the NavBar, the MMB and RMB do not constrain the turntable rotation horizontally and vertically as expected.

  • Using the Magnify View tool leaves a rectangular outline in view windows. Clicking the tool icon does not remove the outline.

    Workaround: Click on the close window icon "X" in the top left corner of the Magnify View tool window.

  • The Checkpoint save Reminder and Pause functionality is not available in Alias 2024.

  • Although you can include special characters in the key combination you use to assign a hotkey (Hotkey Editor), these values will not be imported if you plan to export your Preference Profile and import it later. Therefore, we recommend that you avoid using special characters so you don't lose any hotkey assignments.
