Carbon Graphics Announces Geo STUDIO PRO 3.6: A Focused Update Ahead of its Major 64-bit Transition

Carbon Graphics is pleased to announce the release of Geo STUDIO PRO 3.6, an update that delivers powerful new modeling tools, workflow refinements, and important stability improvements. Although this is a slightly earlier release than usual—due to our development team transitioning focus to the upcoming 64-bit Geo STUDIO PRO 4.0—Version 3.6 still delivers a substantial set of new capabilities that many users have been eagerly awaiting.

Major New Features

New Loft Tool (Rebuilt from the Ground Up)

After many customer requests, the classic lofting functionality from Geo 2.0 has been completely replaced with a modern, flexible Loft Tool. Users can now:

• Loft wall polygons between two selected contours

• Perform multiple lofts within the same session

• Enjoy in-tool undo and smoother interactive workflowsThis new Loft Tool also enables several other 3.6 features, including multi-section hull generation in the Tube Tool.

  
  

Enhanced Orthographic Views

The Front, Side, and Top views have been updated to eliminate long-standing inconsistencies. A new SHIFT + Right-Click context menu provides rapid access to:

• Opposite-side views (Back, Bottom, etc.)

• Background image management

• Additional view-specific options

  
  

Plugin-Driven Radial Menus

Geo’s plugin architecture now allows plugins to update and customize the Radial Menu that is available during the lifetime of the tool session - dynamically, enabling faster tool-specific actions and more efficient workflows.

Major Tube Tool Upgrade

Guided by extensive user feedback, the Tube Tool has been significantly expanded:

• Full integration with all three orthographic views

• Support for variable cross-section counts and shapes

• Contours can now have different vertex counts

• Automatic hull generation using the new Loft Tool

• Tool-specific Radial Menu enhancements

• Perfect for CAD-like blueprint modeling or multi-view construction workflows.

  
  

New Bevel Edge Tool

A highly requested modeling feature:

• Select multiple polygon edges and apply a controllable bevel width

• Automatically adjusts original edges and maintains correct poly sizes

• Supports in-tool undo

• Auto-edge selection when starting from a selected polygon

• “Shrink Mode” (K key) ensures precise vertex picks

• Custom Radial Menu entries for fast operationAn excellent way to quickly soften hard edges or prepare geometry for next-stage modeling.

  
  

New Translate Gizmo

The Translate Tool now supports a full 3-axis gizmo:

• Drag colored cones to constrain motion along X/Y/Z

• Drag colored squares to move along XY/XZ/YZ planes

• Drag the center box to reposition the origin freely

• Combine moves with full in-tool undo

• Adjust gizmo size using “+” and “–” keys. This delivers a modern, intuitive translation workflow while preserving the classic one.

  
  

Cut Insert Tool

A new modeling tool that allows:

• Selecting “parent” and “insert” polygons

• Cutting insert shapes cleanly from parent polygons

• Multiple cuts within one session

• Full in-tool undo. This is a precursor to full boolean operations, planned for a future release.

  
  

New Helper Point Tools

Six new HelperPt tools place pivot points at the selection’s center but offset to ±X, ±Y, or ±Z extremes. This lets users add pivot/reference points without exiting the active tool, dramatically speeding up modeling workflows.

A new HelperPts On Selection BBox tool has also been added.

Duplicate Tool Enhancements

A powerful new auto-repeat feature:

• After the initial manual duplicate & move, users can repeat the operation

• Each repeat moves and copies by the same original amount - Ideal for replicating objects like tables, pillars, rails, or patterned elements.

  
  

Spherical Mapping Tool

New texture mapping capabilities:

• Spherical UV generation

• Configurable Up-axis

• Adjustable U/V scale and offset

• Automatic artifact prevention at seams and poles

• Full Radial Menu integration

  
  

GLTF Improvements & New Extension Support

Importer Stability Fixes

A significant bug has been fixed where primitives using different materials could incorrectly merge vertex lists, causing large memory use and potential crashes. This update greatly improves:

• Stability

• Memory usage

• Scenegraph accuracy

  
  

KHR_texture_transform Support

PBR materials can now use:

• UV offset

• UV scale

• RotationAll applied on the GPU—no baked UVs. Essential for texture atlases.

• 
  

KHR_node_visibility Support

Geo now reads this extension to automatically hide groups and their child polygons. The Hidden flag can also be manually toggled in the Group attributes, enabling powerful hierarchy-based visibility control.

Important Fixes

• Undo list no longer persists after loading new files

• Texture Properties now support separate U/V wrap modes

• Numerous stability improvements across the toolset

  
  

Looking Forward: Geo STUDIO PRO 4.0 (64-bit)

Version 3.6 marks the final major 32-bit release of Geo STUDIO PRO. Carbon Graphics is now focused on Geo STUDIO PRO 4.0, a modernized 64-bit version with deeper capabilities, expanded scene sizes, improved performance, and a new generation of modeling tools.

The target release is January 2026.
