Critical(!) Updates

Windows 10 Fall Update Critical Bug Fix

• Microsoft’s Fall Update for Windows 10 introduces a bug to Application.VisualStyleState that causes the ribbon to become unusable when a File > Open, File > Insert, or File > Save dialog is shown. Alibre presented the bug to Microsoft, and Microsoft acknowledged the bug and plans to fix it. However, no release date is currently available for this fix from Microsoft.
• Alibre has implemented a stopgap patch that circumvents Microsoft’s bug. This results in a slight modification of the appearance of the Alibre Design window by forcing the Windows Vista Glass appearance off.
• If you install the major Windows 10 Fall Update without getting Alibre Design 2018.2, you will be unable to use the software.

Alibre Atom3D

New Features

• Helical Boss and Helical Cut have been added to Alibre Atom3D

Import/Export

• The 2018 versions of DWG and DXF are now available for import/export.

Keyshot 8.x for Alibre Design

• Keyshot 8 is now available.

Performance

• For large assemblies, we’ve made several changes that should improve SaveAs/SaveAllAs dialog interaction performance significantly. Other changes should help improve assembly loading (open) performance.
• Drawings of complex assemblies can now be opened faster. Optimizations for assemblies with many constraints and configurations now improve drawing file load times.

Bug Fixes

• A bug was fixed that occasionally prevented the editing of External Threads.
• A bug that caused the dimension style in-place editing menu in 2D drawings to have overlapping input boxes when the Fit option was selected has been addressed.
• A bug causing an exception during first-run of the Script overlay if the ribbon is disabled has been fixed.
• A bug that caused 2D drawing export to DXF to fail in some cases due to a centerline issue has been fixed.
• A bug causing some add-ons to have issues if the ribbon is disabled has been fixed.
• A bug when overriding the dimension value on the in-place editing menu in 2D drawings that caused the style to also be overridden has been fixed.
• A bug causing a Disposed Cursor Error exception after switching color schemes has been fixed.
• A bug causing issues with new View insertion in 2D drawings when the default units are in Feet and Inches has been fixed.
• Several Alibre Script bugs were addressed.

Misc

• The last-used export type is now remembered between sessions. For example, if you tend to export STL files a lot, you no longer have to select STL as the export format after reopening Alibre Design / Atom3D.
• New APIs to hide reference geometry such as reference planes, axes, and points.
• The Computer Name of the licensed machine will be passed to the Alibre licensing server. This makes it easier for you and for support to figure out which machine needs to be decommissioned if you have a licensing issue. This will replace the “DeviceID” that is currently used, which is a random string of characters.
• A Partner Code license type has been introduced. This does not affect customers.
• A string update in context menus in 2D drawings for consistency
• A German language dialog has been modified.

New Products

Alibre Atom3D

• Alibre Atom3D is a new product focused on consumer and enthusiast customers. It is similar to the legacy Alibre Design Personal Edition but does contain a different feature set.

Alibre Script

• Available in Alibre Design Professional and Expert, Alibre Script is a fully integrated, Python-based scripting language capable of driving nearly everything available in Alibre Design’s API without the overhead associated with making a standalone add-on. It’s particularly useful for automating repetitive tasks or creating 50 parts that vary slightly, for example. Try out some sample scripts.

Removed items

In this release we had to remove 2 pieces of functionality that rely on the same 3rd party technology library that we felt was not a good long-term solution and that is no longer under active development by the technology partner. These items are:

3D Print Analysis
The 3D print analysis feature has been removed. Alibre currently has no plans to replace this feature.

Mesh Support
(See KB Article) – The ability to import, view, or use mesh files (OBJ/STL/etc) has been removed from the software. Alibre does currently have plans to replace this feature, pending an evaluation of available technology partners. We do not currently have a timeline, and an analysis of technology partners is occurring with the following criteria:

• Substantially more robust import and conversion tools
• Customer conversations to ensure we not only replace the previous features but enable more robust workflows
• Other available mesh modeling technologies that might be of interest to our customers

User Interface

Open button on Home Window

• The open button has been moved to the left per customer request
  

Quick Access toolbar

• The Roll View Left and Roll View Right commands have been added to the Quick Access toolbar (near the gem) at the top left of the window. 

Reset View

• The Reset View (formerly Orient to Sketch) tool has been made more prominent near the Select tool in Sketch Mode.

 Renamed tools

• Several tools have been renamed for simplicity. For example, the “Measurement Tool” has been renamed “Measure”.

Insert Axis and Insert Point dialogs now DPI aware

• The Insert Axis and Insert Point dialogs in Sketch Mode now properly display on high resolution monitors.

Bug Fixes

• Cannot create external cosmetic thread if the cylindrical face has any feature on it
• Some users experienced an error: “Attempt to access index __; valid range is 0..__” when editing or creating Notes after a Windows update. This has been addressed. 
• Sketches created via the API could become deformed in some circumstances
• Glitch in displaying complex sketch in canvas when outside sketch mode
• Sheetmetal error with converted conical sheet metal parts
• Flatpattern fails for certain classes of converted sheet metal parts
• Workspace orientation is not respected when project as flat pattern is applied
• Object Ref Error seen when regenerating some legacy sheet metal parts
• An “Unable to create bend law when adjacent flanges are coplanar” error has been fixed

Licensing & Viewer Mode

Passive Licensing

• For customers in extremely secure environments who cannot have data leave their computers during the licensing process, a new licensing mechanism now exists. A license can now be generated by sending Alibre the computer’s Site Key, a short code that looks similar to LSURFTBZQX.

Network Licensing

• Allows customers to install a Licensing Daemon on the internal network via a Linux virtual machine.
• All licensing is done on-network
• Great for large, secure deployments

Viewer Mode

• A new Viewer Mode has been added. When a license is not detected during startup, you have the option of inputting a license or selecting the Viewer option. The Viewer option starts the product in Viewer Mode, which allows you to open and interrogate the model (e.g. take measurements).

Component Upgrades

The following core technology components have been upgraded to the latest versions, giving you access to several years of updates and bug fixes from these component providers:

• ACIS – the core modeling kernel
• 2D-DCM – the 2D constraint manager / solver
• 3D-DCM – the 3D constraint manager / solver
• HLM – the hidden line manager
• ST-Developer – STEP import/export
• Datakit – Import/Export of 3rd party proprietary CAD formats
• Adobe PDFLibs – PDF publishing
• ODA Toolkit – 2D import/export
• The build environment for Alibre Design (Visual Studio) was upgraded

New Import Formats

• Solidworks 2018 import is now supported
• Inventor 2018 import is now supported
• Parasolid 30 import is now supported

High Resolution Support

A lot of effort has gone into making Alibre Design more pleasurable to use on high resolution displays (e.g. 4k):

• Design/Drawing/Assembly Explorer icons now support higher resolutions
• In-Place Editing icons now support higher resolutions
• The Ribbon icons now support higher resolutions
• Grabbing the Design Explorer divider to resize it is easier
• Larger 2D Constraint Symbol option (System Options > Parts/Assemblies > Sketching > Sketch Constraints Size)
• Larger Sketch Node option (System Options > Parts/Assemblies > Sketching > Sketch Node Size)
• DPI-aware selection snap makes selecting things much easier on high resolution displays
• DPI-aware dialogs have been created for many that were not DPI aware – this fixes the jumbled look of dialogs on high resolution displays

General Display Fixes

• Several scenarios where the canvas would be replaced by the “Red X”, for example after waking from Sleep Mode, have been addressed.

New Features

Miter Flange

• Miter flanges (video) can now be created via the Miter option on the new Corners tab of the Flange dialog, dramatically simplifying the creation of many classes of sheet metal parts.

New Home Window

• The Home Window has been completely redesigned.

Graphical Most Recently Used

• On the new Home Window you can see icon previews of your most recently used files, making selecting recent documents easy and fast.

STEP export units

• Previously all STEP files were exported in cm. Now, you can choose which units to use via System Options > Interoperability > STEP

 Configurable Mouse Buttons

• The Zoom, Pan, and Rotate commands can now be customized. If you use several programs, you can now make them all operate the same way.

Pick PDF Engine

• The PDF publishing engine is now an option and can be selected from System Options > Drawings > PDF. If you install a new PDF writer (e.g. PDFill), it should show up here to be selected for use.

Default color scheme

• Small changes to the default color scheme for rollover and preview color
