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.

Editing sketches on parts several levels deep could suffer from performance degradation. They are now more performant.

Some cosmetic changes have been made to the Assembly Save As Dialog to provide a bit more white space in certain areas.

Alibre Atom3D customers now have access to customizable keyboard shortcuts.

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.

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.

The Face Color dialog has been tweaked.

The 2D Drawing View Projection Dialog has had a few cosmetic changes made to it.

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.

The Standard Properties and Custom Properties areas now resize proportionally with the dialog size.

Revolve Boss/Cut and their thin-wall equivalents now offer a Reverse checkbox.

Editing part in assembly which contains imported STP file with different Model Units displays extremely large or small dimension text.

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.

Sometimes sketches saved as Catalog Features would be at an incorrect scale. 

On some models, the number of interferences shown was incorrect.

Some components generated via boolean operations had unexpected Measurement Tool behavior.

White parts may show in blue color in Shaded Views in 2D 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.

Alibre hangs sometimes when importing this DXF file with "m/cm/in" as File units

Label Multi-line Text not displaying properly in template.

Note leader lines now behave more predictably.

Some text with different font sizes incorrectly interpreted with Hoops in 2D drawings.

Reprojecting shaded views with parts with multiple configs puts Alibre in bad state sometimes.

Hatch goes missing from the broken out section view on a shaded view in 2D Drawing and PDF.

Dragging the views in drawing sometimes moved the line weight in different direction.

Dynamic section view shows hollow body in the presence of a face color.

Inserting precise section view could degrades selected facet resolution. 

Changing the Display Header name in the BOM for custom properties cleared the values in that column in 2D drawing.

Lofted flange might change height after unbend followed by re-bend.

Detection for circular dependencies between part features has been implemented to prevent crashing.

Improvements in 2D drawings now handle cases where holes have been patterned or mirrored.

BOM dialog now remembers the last-used BOM template.

More fonts are now supported in 2D drawings

Hatch dialog now remembers last-used settings.

Several core technology components have been upgraded to the latest versions.

Several changes to Script's AutoComplete functionality.

Copy of clockwise elliptical arc gets flipped in Alibre Script. This has been addressed.

Tightly integrated addon is unable to use a BMP or PNG image in DefineTexture api on IADCanvasDisplay interface.

New API for tightly integrated addons to draw text into graphics window.
