Drawing projection requires several steps. One of those steps has been multi-threaded. This can, but does not always, provide a nice speed improvement. Speed improvements are based on a number of factors including geometry, number of views, etc.
Sketch Editing in Large Assemblies
Editing sketches on parts several levels deep could suffer from performance degradation. They are now more performant.
Assembly Save As Dialog
Some cosmetic changes have been made to the Assembly Save As Dialog to provide a bit more white space in certain areas.
Keyboard Shorcuts added to Atom3D
Alibre Atom3D customers now have access to customizable keyboard shortcuts.
Better Placement of Realtime Dimensions
On high DPI displays the realtime dimension box might be placed under the mouse during figure creation, causing frustrating behavior. The dimension input box has been moved further from the cursor.
High-DPI Improvements Product Wide
On high resolution monitors with Windows scale factors greater than 100%, many dialogs in the product had icons that are way too small. These have been addressed. A handful of other dialogs were not high-resolution aware, resulting in chopped off dialogs. These have been addressed.
Some icons have been redesigned to be more clear or visually consistent.
Face Color Dialog
The Face Color dialog has been tweaked.
View Projection Dialog
The 2D Drawing View Projection Dialog has had a few cosmetic changes made to it.
Equation Editor Dialog
Changed some default size settings and modified the way the Name column scales with dialog width, generally increasing its size especially on high resolution displays.
Standard / Custom Properties UI Size
The Standard Properties and Custom Properties areas now resize proportionally with the dialog size.
Reverse Checkbox in Revolves
Revolve Boss/Cut and their thin-wall equivalents now offer a Reverse checkbox.
Very Large Dimension Text on Imported Parts
Editing part in assembly which contains imported STP file with different Model Units displays extremely large or small dimension text.
Face Highlighting in 3D
Highlight issue on hovering over a semi-opaque face in the assembly.
Fixed a case where changing facet resolution may not change facets for some faces on a part.
Catalog Features & Imported Geometry
Sometimes sketches saved as Catalog Features would be at an incorrect scale.
On some models, the number of interferences shown was incorrect.
Measurement Bug with Booleans
Some components generated via boolean operations had unexpected Measurement Tool behavior.
White Parts Showing as Blue in Shaded Views
White parts may show in blue color in Shaded Views in 2D drawings.
Face Colors in Drawings
Face color not showing up in the shaded view when new configurations are added to an assembly.
Sometimes transparent objects are seen behind totally opaque objects in assembly.
DXF Import Hangs
Alibre hangs sometimes when importing this DXF file with "m/cm/in" as File units
Multi-Line Labels in 2D Templates
Label Multi-line Text not displaying properly in template.
Note Leader Lines
Note leader lines now behave more predictably.
2D Drawing Font Size
Some text with different font sizes incorrectly interpreted with Hoops in 2D drawings.
Shaded Views & Configurations
Reprojecting shaded views with parts with multiple configs puts Alibre in bad state sometimes.
Hatches on Broken Out Section Views
Hatch goes missing from the broken out section view on a shaded view in 2D Drawing and PDF.
Dragging Views & Line Weights
Dragging the views in drawing sometimes moved the line weight in different direction.
Dynamic Sections & Face Color
Dynamic section view shows hollow body in the presence of a face color.
Precise Section and Faceting
Inserting precise section view could degrades selected facet resolution.
BOM Header Name Change Clears Data
Changing the Display Header name in the BOM for custom properties cleared the values in that column in 2D drawing.
Lofted Flange Unbend/Rebend
Lofted flange might change height after unbend followed by re-bend.
Detection for circular dependencies between part features has been implemented to prevent crashing.
Centerlines for Patterned / Mirrored Holes
Improvements in 2D drawings now handle cases where holes have been patterned or mirrored.
Last-Used BOM Template
BOM dialog now remembers the last-used BOM template.
More fonts are now supported in 2D drawings
Hatch dialog now remembers last-used settings.
ACIS, DCM, .NET
Several core technology components have been upgraded to the latest versions.
API / Script
Script AutoComplete Improved
Several changes to Script's AutoComplete functionality.
Script Elliptical Arc Copy Bug
Copy of clockwise elliptical arc gets flipped in Alibre Script. This has been addressed.
Image Support in API
Tightly integrated addon is unable to use a BMP or PNG image in DefineTexture api on IADCanvasDisplay interface.
New API for Text on Canvas
New API for tightly integrated addons to draw text into graphics window.
