3DCS Best Fit and Optics Analysis - Beam Direction, Optical Sensors, Autonomous Controls Applications

3DCS Best Fit and Optics Analysis Webinar February 23rd

The team at DCS will be presenting a detailed walkthrough of analyses focused on Best Fit scenarios for Locators, as well as controlling variation for sensor and beam projection in addition to a series of advanced functions for modelers

February 23rd, at 11 am EST, DCS will be presenting a free webinar on advanced modeling techniques that include a number of use cases that clearly show how tolerance analysis plays a role in far more than gaps and flushes.

A simple agenda belies a packed event:

Best Fitting Complex Assemblies
Light Projection and Optic Analysis
Advanced 3DCS functionality

The Best Fit Move Gives You Solutions to Complex Assembly Issues

The Best-Fit move is similar to the Six-Plane move except that it can have more than six pairs of locators defined. Like the Six-Plane move, each pair of locators needs a direction defined. Then, each object feature is best-fit to each target plane. Each target plane is defined by the target feature and the direction. If 4-way hole-pin pairs are locators, they need to be selected twice with two normal directions, just as in the Six-Plane move.

The Best-Fit move can fit multiple object parts to the target part(s). The object parts are independent from each other if points on each object part are used to locate each of them.

In addition to Best Fit, a number of advanced techniques will be shown and discussed -->

Dynamic MidPoint - Basic function is creating a midpoint between two points
Avg pt Move - Moves a point to the average center created by multiple points (DLL)
Iteration Move - Rotate or translate a part to converge onto a desired measurement value
MTM groups - Group MTMs to organize and simplify your navigation tree (MTMs - Moves, Tolerances, Measures)
Combination Measure - Add, Subtract, or find the Minimum or Maximum value of a group of Measurements
Non-Output Measurements - Maintain a measurement as active but not output it in the final results
Model Variants - Used to change the model to a different scenario quickly using different Moves, Tolerances, or Measurements
Hide/show feature - Clean up your graphics for easier understanding
Mesh color control - Offset part mesh colors in your graphics for easier understanding

This model discussion will give you a deeper understanding of methods already available to you in 3DCS, as well as insight into a number of modeling methods that can help you to become more proficient and efficient in your future modeling projects. This first half alone is enough reason to join the webinar, but we left the coolest model for last.

Optical Alignment Analysis for Beam Direction, Sensors, and Controls

Similar in scope to Valeo's presentation at the DCS User Conference (you can find a summary here) which controlled for dimensional variation that influenced the projection of the user interface on the windshield of a car, this model focuses on how dimensional variation affects the beam direction of a headlight, providing methods to control the variation and ensure proper beam projection.

This modeling method applies just as functionally to optical sensors for a multitude of applications including user interfaces and display projections, cameras, lights, and laser trackers. Dimensional variation affects far more than just simple gaps and flush conditions and often influences non-dimensional features that can cause headaches at final assembly. What's more, the plant team is left scratching their heads when the source of the problem isn't intuitive. 3DCS provides the tools to quickly find these issues, whether predicting them during design or using plant measurement data to root cause the issue at final production. (You can see an example of this in Philips Medical's analysis of beam direction in an MRI-based radiation therapy machine here)
