Carbon Design Engine Release Notes

The Carbon team is always working on new and improved features for its powerful design software. The latest updates described here can improve your designs and overall user experience.

MARCH 27, 2024

Tiled textures

In addition to random “noise” textures (released in Carbon Design Engine™ software in 2023), users can now add decorative tiled textures to meshes. Tiled options appear as new entries in the “Pattern” drop-down menu within the existing Texture operation:

  • Cube
  • Diamond
  • Dot
  • Grid
  • Hex
  • Pyramid

Tiled pattern options:

Embedded controls allow users to control the tile size (the size of each individual texture feature) and depth (embossed or debossed) of the pattern. The selected texture can also be inverted to create a negative version of the pattern.

Note that patches must be contiguous for a successful texture application; process unconnected patches as separate Texture operations.

For users familiar with accessing tiled textures with the Print Preparation interface, applying textures in Design Engine should be faster and more robust. Additionally, editing a texture once applied (e.g., changing the pattern, tile size, depth, or boundary decay settings) will return a fast revision result for easy design iterations.


Remesh creates a new triangle mesh representation of your geometry with more regular triangles. Remeshing may be useful if a poor-quality mesh is limiting the outcomes of surface operations (e.g., texturing).

Remeshing typically creates more triangles to better represent the desired geometry, and therefore increases file size.

Access Remesh from the new “More mesh tools” drop-down next to the Decimate operation

Example: Remeshing a surface for optimal tile texturing

Replace Mesh

Any Input Mesh can now be replaced with an alternate mesh using the “Replace Mesh” feature. “Replace Mesh” will swap out the mesh in all operations in which that mesh is selected. This can be useful if you need to swap in an updated version of a file without redoing Operations work, or if you wish to duplicate a previous project to reuse a list of Operations on a different model file.

Note that any patches present on the original mesh will need to be reselected after replacing a mesh.

Replace Mesh is accessed from the menu options available for each Input Mesh.

Additional Part Info

Additional part information is now available for input meshes, including volume, units, and triangle and vertices counts. Click “View Info” from the Meshes menu to access information. Note that some fields may be unavailable for some meshes and/or for some users.

Large, complex meshes (typically >50 MB and/or >1,000,000 triangles) can be challenging to work with due to long processing times. Decimating a mesh reduces the number of vertices and triangles to simplify mesh geometry.

Consider decimating a mesh whenever your file is >50 MB, has >1,000,000 triangles, or when you know that your model contains more triangles than is necessary to accurately represent the desired geometry. Experiencing lagginess or slow processing might also be an indication that decimation could be helpful.

Decimate is a new option in the top menu, near “Upload” and “Add Shape.” Decimate is intended for input meshes only; Carbon does not recommend decimating generated meshes.

Note that decimation can cause your model to lose detail as triangles are removed/combined. This impact will vary based on geometry; there is no single “right” level of decimation or target number of triangles for all geometries. Decimation is reversible and alterable; consider trying different decimation percentages to get the desired outcome.

Following is an example of how decimation can impact model geometry. The optimal level of decimation for a model will depend on your use case.

Undecimated mesh
Mesh decimated to 50 percent
Decimated to 50% (50% of triangles and vertices retained)
Mesh decimated to 1 percent
Decimated to 1% (1% of triangles and vertices retained)

Decimate has been released as Beta functionality at this time; please submit any feedback to

“Zoom to fit” navigation control (center on this point)

A new “Zoom to fit” navigation control allows you to quickly center a part in the project area and zoom to the extents of the mesh. To access this command, press the F-key, select “Zoom to Fit” from the top-bar View menu, or select “Zoom” from the Meshes menu for a specific input or generated mesh.

Import STEP Files

STEP files can now be uploaded to Design Projects. The entire assembly will be converted to a single triangle mesh.

Note that meshes cannot be downloaded in STEP format (STL, PLY, and OBJ are the available download format options).

Reordering operations preserves inputs and dependencies

Moving operations within the operations list now retains inputs and other dependencies.

Note that an operation might need to be updated after it or a related operation is moved; watch for a red marking on an operation to indicate that it requires edits before proceeding.

Moving operations

New interface for “Settings” menu

Historically, clicking the Design Project name has opened a menu with various options (eg, Duplicate, Rename).

These options have now been moved to a “Settings” control panel. Here, you can Duplicate a design, Lock a design (see the following section for more information on this new feature), change the project name or material, or Delete a design. Access “Settings” by clicking the Design Project name.

Lock Design

A Design Project can now be locked to protect against unwanted or unintended edits.

Click the design name to launch the “Settings” control panel, then click the “Lock” icon. This action can only be performed by the project owner.

A locked Design Project can still be duplicated by any user with access, and a project owner can unlock a project at any time.

Access Lattice Search from Toolbar

Carbon offers a robust Lattice Search tool to help you identify an effective metamaterial (a combination of a material and a lattice design type) for your application based on desired performance and design requirements. Lattice Search can help you get started on a new project by quickly narrowing the vast field of potential lattices to the ones most likely to accomplish your goals.

Lattice Search has long been accessible from within the latticing operation; you can now access Lattice Search directly from the top-bar menu.

Lattice Search
Example: Access Lattice Search from the blue button in the top right-hand corner of the screen
Search Results
Example: Lattice Search allows you to quickly search for lattice types that meet design and performance requirements.

Learn more about using the Lattice Search tool (including as an example of finding a lattice to substitute for a specific foam material) in the Design Engine Tools and Features course.
