Repair The Meshes That Other Software Can't!

LimitState:FIX takes the powerful mesh processing technology of Polygonica, developed and proven over two decades, and embeds it in an easy-to-use tool that automatically heals your 3D mesh files, ready for print or other end use.

In testing, LimitState:FIX quickly identifies and fixes a wider array of mesh errors than alternative commercial and free repair tools.

Key Features

 

Auto Fix

At the heart of the software is the Auto fix function, which quickly and systematically fixes all the errors in a model according to the user-defined settings.

Close Solids

Select from a range of hole closing algorithms, including ones that prioritize planarity, smoothness, compatibility with existing features or model contours.

Orient Normals

LimitState:FIX will systematically identify and fix polygons in a mesh that are incorrectly oriented.

Fix Self-Intersections

LimitState:FIX checks if a objects are self-intersecting and fixes them if they are, while ensuring that the final geometry is as close as possible to the original.

 

Remove Noise Shells

Solids can often contain small shells as well as the intended geometry. LimitState:FIX identifies these shells and removes them from the model.

Make Manifold

Many applications that deal with mesh files require a manifold mesh in order to function correctly. LimitState:FIX will query whether a mesh is manifold and, if it isn’t, repair it.

Platform Layout

For files containing multiple solids, LimitState:FIX contains functionality to snap to the baseplate, automatically arrange and scale the objects, as well as validate the layout within the selected print platform.

Export Slices

As well as exporting a healed file in mesh format, LimitState:FIX has the capability to save generate slice files (SLC or CLI) for use directly or in path planning.

 
 

LimitState:FIX 4.0 extends the capabilities of the software; building upon and enhancing the existing features, as well as adding new functionality to fit into the workflow of mesh fixing and preparation for 3D printing.

Improvements include:

  • LimitState:FIX 4.0 introduces a multiple-object interface, allowing you to heal and manipulate numerous mesh files at the same time - dramatically increasing process workflow and productivity.

  • LimitState:FIX 4.0 introduces a flexible project platform. Choose from a number of popular 3D printers or automatically size the volume based upon the objects you’ve imported. Once healed, objects can be arranged to optimize the use of space within the available volume - essential for efficient 3D printing projects.

  • For processes that require models to be provided in slice format, LimitState:FIX v4.0 allows users to export a healed mesh as both SLC and CLI.

  • The hole closing workflow has been completely re-worked for LimitState:FIX v4.0, meaning that repairs can now be undertaken up to 200 times faster when compared to previous versions.

    • Contour: Join vertices at similar elevations

    • Features: Triangulate across a hole by connecting similar features

    • Features (Smooth): Triangulate across a hole by connecting similar features, while also taking into account the surrounding geometry

  • New icons and a clean workspace ensure that usability is improved and productivity is accelerated.

  • Re-size, rotate and translate objects within the platform environment.

  • Where meshes are comprised of multiple shells, LimitState:FIX4.0 can automatically separate these into their constituent parts and export the healed objects as individual files.

  • Minimize waste and lost time by ensuring that objects lie within the build platform and clashes are eliminated, before they are sent to print.

  • We’ve upgraded the core functionality of LimitState:FIX to use Polygonica 2.3, which brings improvements in a wide range of areas.

  • LimitState:FIX 4.0 saves files at a precision that promotes compatibility with other mesh manipulation software (previously, higher levels of precision meant that false positive errors were encountered when importing fixed files into other applications).

Frequently Asked Questions

  • There are no upfront costs. Each purchase provides you with a 12 month license for LimitState:FIX.

  • You’ll be emailed an activation key that you can use to license the software.

    Each key will provide a node locked license for the machine that it is activated on and each key is valid for the number of activations that you have purchased.

  • We appreciate that system updates, hardware failures and new machines all mean that you might have reason to require a license swap mid-contract. For this reason, we’ll provide a replacement activation key on request - simply email licensing@limitstate.com.

  • Any user with a valid license can upgrade their copy of LimitState:FIX at no additional cost, whenever a new release becomes available.

  • Subscriptions to LimitState:FIX are paid annually.

 Benefits

Industry-Leading Mesh repair Technology

Utilizes the powerful Polygonica mesh processing tools to provide quick and robust healing of error-filled 3D mesh files. Close solids, fix face orientation, make manifold and more, all in a single click.

 

Increased Productivity

Accelerate build preparation using one simple software solution. Optimize your workflow from receipt or generation of a file, through to manufacture.

Print-Readiness Tools

Scaling, rotation and automatic nesting algorithms ensure solids are optimally located within the defined build volume, in advance of validation and export in production ready mesh or slice format.

“I spent many hours trying to manually fix a model with other professional tools, but LimitState:FIX did the job in under a minute.”

Case Studies

Auxetic lattice material fixing

Auxetic materials expand, rather than thin, when stretched. Here, LimitState:FIX was used to heal the geometry of an auxetic structure that was produced and manufactured by the Mercury Centre for an aerospace client. The original mesh contained almost 7 million faces and many hundreds of thousands of errors.

Complex chassis component

As seen in Wired magazine, this prototype chassis component for motor-sport application uses advanced design and manufacturing techniques. The original model contained almost 140,000 self-intersecting mesh faces, and 16,000 non-manifold edges. Impossible to heal manually, LimitState:FIX repaired the file in under one minute.

Fire extinguisher

A familiar 3D design, of a fire extinguisher. Issues are highlighted in red, and there are many in this model - 2,500 open edges and 6000 self-intersections. Although the model looks right, it wouldn’t print, and it would take a very long time to fix all the problems. LimitState:FIX automatically resolves all the issues with this model in seconds.
