What’s New: URDF Export, Control Point in Edit Curve, G3 Support in Connection Analysis

This update brings a focused set of refinements across CAD, Model-Based Definition (MBD), Simulation, Render Studio, Mobile, and the Learning Center, delivering greater precision, clarity, and creative control across Onshape workflows.

CAD Improvements

URDF Export

Onshape exports natively to the Unified Robot Description Format (URDF), the standard file format for describing robot models in simulation environments such as ROS, NVIDIA Isaac Sim, and more. This eliminates the need for external conversion tools and streamlines robotics design workflows end-to-end.

Edit Curve – Control Point Improvements

Edit Curve ships with improved control point behavior, delivering smoother and more predictable curve manipulation. Achieving the exact desired shape takes fewer adjustments and less time.

Connection Analysis – G3 Support

Connection analysis evaluates G3 (curvature rate of change) continuity, giving surfacing designers the ability to verify the smoothest possible transitions between surfaces. This is a critical capability for Class-A and aesthetic surfacing work.

MBD – Minimum and Maximum Cylinder Distance

MBD dimensions support minimum and maximum cylinder distance annotations, enabling more complete and precise communication of cylindrical feature requirements directly within the 3D model.

MBD – Fillet Dimension

A new Fillet dimension tool in MBD automatically associates the fillet default tolerance schema, ensuring the correct tolerance value is applied every time on both native and imported parts.

Improved Row Highlight for Table Rows in Onshape Tables

Table row highlighting in Onshape tables delivers sharper visual clarity. Active rows stand out more clearly across BOMs, configurations, and custom tables, reducing errors and speeding up review.

In-Context Without Insertion

Parts created in-context within a Part Studio no longer require immediate insertion into the originating assembly.

Mate Connector as Reference Coordinate System for Measurement

The Measure tool accepts a Mate Connector as a reference coordinate system, returning dimensions relative to both the position and orientation of the selected Mate Connector rather than the default coordinate system. A new quick list view for measurement selections also makes it faster to review and remove any selected references.

Use Pen Input as Mouse

Onshape treats stylus and pen input devices as full mouse equivalents. Users on pen-enabled tablets and touchscreen devices get a more natural and fluid design experience without any loss of precision.

Simulation Improvements

Solver Performance

A new update to the Onshape Simulation solver delivers noticeable speed improvements in Modal Analysis and Linear Static Inertial Relief.

Render Studio Improvements

Render Studio Projector Auto-Fit

The Render Studio projector gains an auto-fit option, automatically adjusting the projection to best match scene geometry. Scene setup moves faster, and projected textures and patterns align correctly without manual fine-tuning.

Render Studio Advanced – Environment Lighting

Render Studio Advanced introduces expanded controls for environment lighting, opening more creative options for scene composition. Fine-tune environment maps, manage multiple light sources, and produce more realistic and polished product visualizations.

CAM Studio

Post-Processors

Machine support has been added for the following:

Mobile Improvements

Sketch Chamfer

Sketch Chamfer arrives in the Onshape mobile app for iOS and Android. Add chamfers to sketch profiles directly from a mobile device.

Section View Preserved for In-Context Edits

Inside of an assembly on iOS, you can create a Part studio and preserve the Section view if it is active when creating the context state, enabling better visualization of your assembly's current position when designing parts in-context.

Learning Center Improvements

Model-Based Definition (MBD)

The Learning Center now offers the Model-Based Definition (MBD) course, where you learn how to work with the Inspection table and build out your MBD data directly in Onshape.
