What’s New: Hole Callout Updates, Hole Selection in CAM Studio, Render Studio Advanced

The last official Onshape release of 2025 offers some highly requested goodies, including robust methods for displaying hole quantities on drawings, never-before-seen realism with the Volume entity in Render Studio Advanced, and CAM Studio usability improvements.

Drawings

Quantity for Hole Callouts

Hole callouts in Drawings now support displaying quantities, improving clarity when documenting drilled holes.

Rectangular Border for Detail View Creation

Detail views now support a rectangular boundary option in addition to circular profiles, splines, and closed polygons.

Render Studio Advanced

Volume Entity

Render Studio Advanced introduces Volumes, enabling more realistic visualizations of volumetric objects such as fluids, smoke, gels, or translucent bodies. A volume can optionally be an OpenVDB 3D texture. Non-advanced users can open a scene that contains Volumes, but their properties are non-editable. Learn how to Create a Volume.

Sample OpenVDB volumes can be found at the OpenVDB website.

CAM Studio

CAM Jobs User Interface

The Jobs tree in CAM Studio has been redesigned to align more closely with native Onshape UI patterns, improving usability, clarity, and consistency across the platform.

Hole Cutting Strategy

Hole selection workflows now support improved ordering behavior, allowing hole-making operations to follow more predictable and intuitive selection sequences.

Reverse Face Normals

A new option allows you to reverse face normals directly within CAM operations, simplifying toolpath generation and reducing the need to modify geometry in the Part Studio.

Mobile

Support for Configurable Variable Studios

The Onshape mobile apps for iOS and iPadOS now support viewing details of configurable Variable Studios, allowing you to understand part and assembly behavior directly on mobile devices.

Learning Center

Inspection And Repair Tools

The Learning Center now offers the Inspection and Repair Tools course, where you’ll learn how to detect and resolve missing references using Onshape’s diagnostic tools, including the Profile Inspector, Constraint Manager, and Repair panel.
