Autodesk Alias 2027 introduces enhancements to core modeling tools, including a redesigned Combine Surfaces tool and extended functionality for Subdiv Retopo and Subdiv Cut. The release also improves Diagnostic Shade surface evaluation and visualization, Live Referencing, and VR/XR viewing, while addressing numerous customer‑reported crashes and issues.
For new features and enhancements in this release, see What's New in Alias 2027.
| General |
|---|
| Resolved Alias crashes related to undocking the Control Panel. ALS-32751 |
| Selecting the Text tool or Markups no longer causes Alias to crash or freeze when .otf fonts are installed. ALS-3354 |
| When reloading a stage from the Stage Editor, the file browser now lists all supported file types not just .wire files. ALS-33442 |
| Information Window: Fixed an issue that caused Curvature Radius values to be off by a factor of 10. ALS-33163 |
| When using multiple monitors with Always Ask on in the Paste options, the paste/layer list now consistently appears near the mouse pointer instead of on random monitors. ALS-34130 |
| Fixed a crash that occurred when selecting (POI) Point of Interest in the SBD window to retrieve position information in the Information Window. ALS-33710 |
| Fixed an issue where changes made to Alias settings in the 3DConnexion (SpaceMouse) software were not consistently reflected in Alias after rebooting or updating device settings. ALS-33396 |
| UI |
|---|
| Pressing Ctrl + Spacebar now opens and closes the Shader Lister window as expected. ALS-32726 |
| Fixed the Non-Proportional Scale view in the viewport so users can interact without repeatedly clicking the icon. You can also click the icon once, then hold Shift + Alt and drag in the viewport to scale the view. ALS-28336 |
| When you have multiple stages open, the stage tabs no longer scroll unexpectedly when pasting geometry into the active stage. ALS-33504 |
| Fixed an issue where pressing Ctrl + Spacebar did not hide certain floating windows. ALS-33464 |
| Insert New Layer from Objects now works as expected when the source layer is off. A new layer is created including the selected objects instead of creating an empty layer. ALS-33473 |
| Custom shelf icons no longer display black after importing or merging profiles. ALS-27798 |
| Modeling |
|---|
| Resolved an issue where Render Settings were lost when switching stages in VRED rendering mode. ALS-32701 |
| Fixed the Surface Fillet tool to maintain expected span count and continuity compared to previous versions. ALS-32389 |
| Improved performance of the Reference Manager with Alternatives compared to previous versions. ALS-31147 |
| The Symmetric Modeling tool now works on previously failing objects without requiring Zero Transform. ALS-16668 |
| When using the Curve and COS Trim Tool with Keep Originals turned off, undo now correctly removes the trimmed curve results instead of leaving unintended curves behind. ALS-33480 |
| Freeform Blend tool: Selecting Undo All now restores the blend operation without removing the Curve on Surface that was just created to support that blend. ALS-33230 |
| Subdiv Insert Edge tool: Adding multiple edge loops and then using Ctrl + Z to undo them no longer corrupts the subdivision geometry. Incremental undos now restore the model correctly. ALS-31559 |
| Using the Dynamic Measurement tool with Snap to Curve turned on no longer causes flickering edges or off‑edge end points. ALS-33814 |
| The Align tool now correctly shows true/projected intersection snap points when aligning one curve to another. ALS-33469 |
| Subdiv Cut tool: Snapping the start point to a CV with Ctrl pressed, releasing Ctrl now frees the snap so you can move the starting point off the CV, making the snapping behavior consistent with other tools. ALS-32746 |
| Alias no longer introduces a deviation from the original surface when a periodic shape is extruded and the degree is later increased. ALS-32594 |
| Multi-surface Draft tool: Fixed an issue where the Continuity Check locator did not appear for degree‑1 curves. ALS-33750 |
| Fixed an issue where continuity locators appeared to break after flipping geometric normals on Square or Rail Curvature surfaces created with Continuity Check enabled. ALS-25672 |
| Curve & COS Trim tool: When using Project Curves, trims no longer intermittently remove the wrong side or create offset trims; repeated operations now yield stable, predictable results. ALS-33783 |
| Surface to surface deviation behavior has been corrected to produce consistent and reliable results within construction tolerances. ALS-31772 |
| Visualization |
|---|
| Fixed an issue where modifying a linked shader using Assets > Modify from the More menu did not correctly update in the user interface. ALS-33246 |
| Fixed an issue where copying and pasting geometry with a VRED material, which included a texture map, duplicated the material unnecessarily. ALS-32754, |
| Fixed inconsistent UV mapping behavior in VRED render mode for decal projections. ALS-32689 |
| Fixed visual artifacts created by Screen Space Refractions when switching between orthographic face views of the perspective window. ALS-32555 |
| Resolved an issue where overwriting a texture file did not refresh the texture in Alias. ALS-32548 |
| Alias no longer crashes when deleting unused shaders from the Shader Lister when Image-Based Lighting is on. ALS-33671 |
| Updating a VRED asset using Modify Material and Save Material no longer embeds VRED render materials in a way that unnecessarily increases .wire file size. ALS-33678 |
| Shader preview thumbnails are now cached and reused as expected, speeding up Shader Lister refreshes. ALS‑32764 |
| Shader Lister: Sort By settings now persist after saving profiles. ALS-34036 |
| Self Shadows no longer cause dark artifacts on subdivision edges. Auto Render Clip is now on by default. ALS-28918 |
| Fixed an issue where shaders disappeared from the Shader Lister when switching between stages. ALS-34198 |
| Animation |
|---|
| Using Output Image in VRED render mode no longer degrades viewport performance. ALS-33229 |
| Data Transfer |
|---|
| Resolved issues with untrimmed surfaces when exporting to NX .prt and importing back into Alias. ALS-32740 |
| New Data Translator: Fixed NX export to correctly handle curves with weighted CVs. ALS-32543 |
| Exporting data to NX with Split Periodic Surfaces turned on no longer splits non‑periodic surfaces. ALS-31974 |
| Dynamo |
|---|
| Resolved an issue where Dynamo inputs were lost after saving scripts under a new name. ALS-32512 |
| Resolved inaccuracies in Dynamo calculations when a construction plane was active in Alias. ALS-32256 |
| The Flacon Generator script now works as expected. A new version of the script (flcgen_2027.0.2.dyn) has been added to the Dynamo Player scripts. ALS-32611 |
| API |
|---|
API functions that rely on mapscr() now correctly convert application‑relative screen coordinates to window‑relative coordinates before mapping. ALS-34020 |
Meshes exported from Blender may affect the geometric surface orientation of Alias geometry. For example, when you have a Blender mesh in a scene with Alias geometry, using the Set Geometric Surface Orientation tool on the Alias geometry may not work as expected.
Workaround: Hide the Blender mesh before working with Geometric Surface Orientations.
When working with Live Referencing between VRED and Alias, using files stored on a network location, promoting changes in Alias turns off Enable Live automatically. This occurs for any promoted feature, including: materials, variants, annotations, and sections. Further updates from VRED to Alias no longer occur because Live Referencing is disabled.
Workaround: After promoting changes in Alias, manually re‑enable Enable Live to continue receiving updates from VRED. Once Enable Live is turned back on, Live Reference updates work as expected.
When working with Live Referencing between VRED and Alias, changes made in VRED can be lost after sending overrides to Alias, depending on the update order and user actions in Alias.
This can happen in the following sequence of events:
In VRED:
In Alias:
You Promote some or all of the VRED overrides.
Promotion updates the Live Reference data and makes the changes part of the Alias file.
In VRED:
You manually update or Auto‑Update.
During this update, VRED discards the promoted overrides because they are no longer owned by VRED.
In Alias:
In VRED:
Workaround: Save your VRED file before selecting Send Overrides to Alias.
When promoting Live Reference overrides from VRED to Alias, Switch, Multipass, and Layered materials do not promote correctly. Switch materials promote only the currently active child material instead of the switch. Multipass and Layered materials promote but are not applied to the geometry.
When promoting Live Reference overrides from VRED to Alias, materials assigned to objects on stitched shells may not promote correctly. In some cases, the expected material assignment is missing, and variant overrides may also fail to transfer.
When you send Live Reference overrides from VRED to Alias and promote them multiple times, Alias may create duplicate annotations. The annotation count appears unchanged before promotion, but promotion adds duplicates.
Workaround: Associate the VRED annotation with the Alias layer instead of a child node before sending overrides.
