To get started - import a ".STEP" file.

The system recognizes all meta data from your .STEP file; dimensions, tolerances, GD&T annotations, part names, part colors, sub-assemlies, ...

‍

Keep your work up-to-date anytime.

The "iteration feature" allows you to import a new .STEP file; the system then automatic recognizes parts. You only have to approve/adjust changes in your model from the previous import.

‍

If you don't have a .STEP file yet - and start from a blank piece of paper - you can create a project without a .STEP file.

This allows project teams to:

- Draft critical tolerance stacks
- Plan a shared vision of a product architecture
- Plan an exact constrained system design

‍

Automatic stack-up detection
Get instant help to set-up tricky tolerance stacks and check if tolerance stacks are ambigious (to avoid overconstraints).

Define a 'Point of Interest' and let the system identify possible tolerance paths. See the video to see an example.

Setup a product archtecture from scratch or inherit the architecture from the .STEP file.

From an initial import-setting "interface definition" - the system identifies all interfaces between parts.

The architecture feature let's the user(s) arrange and re-arrange parts in assemblies and sub-assemblies to make tolerance analysis easy and simple.

The interface map feature aids the users by a graphical overview of the product architeture.

The system automatically generates the map. A mapping of part or sub-assemblies and their interfaces.
‍
This feature is helpful to:
- layout product architecture
- divide work-tasks or areas of responsibility
- spot complexity (if the map looks like spaghetti you are most likely overcomplicating things and makes it imposible to make any valid tolernance analysis)

From the "Path Finder" feature - automatically setup a given tolerance stack. Based in the identified path the system automatically sets up initial parameters for the stack to get the user off to a quick start.

‍

The system offer the ability to manually setup stacks - handy pre-CAD - to estimate performance of critical features before development.

Assign nominal values, tolerances, distributions, Cp, Cc and/or Cpk values.

Handle 2D and 3D stacks.

The system allows you to setup multi-dimensional stacks. In combination with the iteration feature the analysis can be refined during the development process.
‍

Set-up non-linear stacks. Calculate forces, pressure, your commute-time-to-work, only your imagination sets the limit - as long as you can provide a mathematical expression.

The system works with all standard math-operators such as cos, sin, cosh, sinh, Pi, etc.

Refine tolerance stacks with GD&T modifiers such as Symmetry, Straightness, Total Runout, Circular Runout, Profile of a Surface, Profile of a Line, Position, Perpendicularity, Parallelism, Flatness, Cylindricity, Concentricity, Circularity, or Angularity.

Draft tolerance stacks and allocate estimated tolerances based on sketches or illustrations.

Annotate on sketches to draft and communicate design intents.

Keep the design history. After sketching - link the paramenters to the CAD model.
‍

The system allows you to look-up and assign tolerance on the fly based on the ISO 286 IT grade standard.

The user can either input a tolerance and then calculate the corresponding IT Grade or input a tolerance grade and then calculate the related tolerance.

Take screenshots from the embedded 3D viewer directly into the 2D Documentation Canvas.

Easy annotation of stacks by:
- Point of Interest annotation
- Leader lines
- Arrows

Automatic link of annotation to parameters.

The canvas is an "infinity canvas" and can be used to add notes, screenshots, stickers to support the development and thought process.

Identify impactful parameters - often a source for optimization.

Easily preview the impact of publishing your parameter changes

"What if" this parameter changes? Instantly check the impact on other calculations.

E.g. handy in case if a part is out of specification. Check the impact in seconds.

Collaborate real-time with colleagues 'google docs style'.

Cloud based system: no check-in or check-out.

Manage and control access/viewer rights.

Our technology is built on world-leading interface engine.

Here you see an illustration of two parts - a grey and a purple.
Our 'X-ray' mode lets you inspect functional surfaces between the parts.
‍
In this case almost all functional surfaces are highlighted in orange - indicating overconstraints. This results in unnecessary complexity for tolerancing.

Contrary to the other example with an overconstrained design - here's an example with no overconstraints.

The 'X-ray' and constraint evaluation engine determine that there are no overcontraints and that the part is ideally constrained - indicated by green functional surfaces. The parts are exact constrained and hereby easy to tolerance.
