Solution: Go to Edit > Preferences > Performance. Reduce the "Undo level" from 50 to 10. The 64-bit version handles RAM poorly when storing large undo histories.
If you manage to get your hands on this software, here is the feature set that makes it legendary: artcam 2011 64bit top
To understand the value of “ArtCAM 2011 64bit top,” we need to rewind to the early 2010s. Before Autodesk acquired Delcam (the original developer) in 2014, ArtCAM was the industry standard for artistic CNC programming. Version 2011 arrived at a pivotal moment.

The computing world was shifting from 32-bit to 64-bit architecture. Standard RAM was moving from 2GB/4GB to 8GB+. Older versions of ArtCAM (2008, 2009, 2010) were largely 32-bit applications, meaning they could only address a maximum of 4GB of RAM—and effectively, often less than 2GB for the application. Nesting: Automatic arrangement of parts to minimize waste
ArtCAM 2011 introduced a robust 64-bit version. This was a game-changer. For the first time, users could load massive 3D relief models, create high-resolution bitmaps, and generate complex toolpaths without the dreaded “Out of Memory” crash. The “top” configuration of this version refers to running it on high-end 2011-era hardware (or modern virtual machines) to maximize its potential.
