What’s New: Cosmetic Threads, Routing Curve, Constrained Surface

With our fourth release of 2025, we've got some wonderful improvements in a variety of different areas. Let's have a look.

CAD IMPROVEMENTS

COSMETIC THREADS (3D)

When defining a thread using the Hole feature, or External thread feature, cosmetic threads are rendered on-screen in the modeling environment.

ROUTING CURVE

The new Routing curve feature assists with many 3D curve workflows including wire, tube, and pipe routing.

CONSTRAINED SURFACE

The new Constrained surface feature allows you to create a surface fit through a series of selected points or defined entirely by a mesh.

MOVE BOUNDARY - UP TO WITH OFFSET

The Move boundary feature now allows for an Offset distance to be defined when using any of the "Up to" end conditions.

FRAMES - LOCK PROFILE FACES

The new Lock profile faces option in the Frames feature allows you to lock your frame profile to follow one or more selected faces. This allows you to correctly introduce twist in your frame elements, to accurately follow non-planar curves.

ASSEMBLY SUBFOLDERS

You may now nest folders in the Assembly Instances list, to create assembly subfolders.

EXPAND/COLLAPSE ALL FEATURE FOLDERS

You may now expand or collapse all feature folders in the Part studio Features list and Assembly Instances list in a single click.

EXPORT TO RHINO - SELECT VERSION

When exporting to a .3dm file for Rhino, you can now select what file version to create.

DRAWINGS IMPROVEMENTS

DIMENSION THREADS

You can now directly dimension threads on your Onshape drawings using the Dimension tool.

RENDER STUDIO IMPROVEMENTS

ADD TEXTURE TO APPEARANCE - IMPROVED WORKFLOW

The process for applying a custom texture to an appearance has been greatly improved. You may now directly add a bitmap image by right-clicking on an applicable Appearance panel parameter and selecting Use bitmap file from the context menu.

LINK TO PART STUDIO APPEARANCE

A new Appearances list context menu option, Link to Part Studio Appearance, is available. This removes the applied Render Studio appearance, and instead re-link the entity to the original Part Studio appearance.
