Linux X68_64 support
(... for downloading CYCAS public beta for 64bit, please follow the topic >Forum and >CYCAS 3.90 public beta test.)

Export 3DS: Initial support for 3D studio exports (in CYCAS pro only)

PDF compression: documents are shrinked to about 20% of the original size

Initial integration of Boolean set operations on 3D objects and walls using GTS (The GNU Triangulated Surface Library gts.sourceforge.net)

• Union, Difference, and Intersection functions in 3D menu
• GTS file import and export functions
• Limitations:
  GTS fails if 2 elements only touch each other
  GTS may fail on very complex geometry
  Walls are converted to 3D objects.. there is no way back
  

• new Hidden Line renderer (HLR pro), more robust and error free
• new options (in CYCAS pro only)
• smoothing of rounded objects with adjustable angle
• support for silhouette highlightning
• support for dashed hidden edges

SVG enhancements: now uses px units (should fix inkscape scaling problems)

DXF enhancements: updated HEADER and TABLES sections for better dimension support

Bugfixes:

• Locale environment no longer overwrites numeric settings (could cause crashes under some environments)
• Paste function now works reliable in 3D view
• Fix for orientation problems on 3D Sphere and 3D Tube elements
• Fix for random rotation problems for 3D Tube elements
• Fix for movement of dimension figures
