Shanghai 3DCS User Conference Begins Next Week May 15th -- See What It Entails!

2019 DCS Asian Users' Conference - Shanghai, China May 15 - 17

ETA-China hosts the 2019 DCS Asian User Conference in Shanghai China to create a space for 3DCS users to share their successes and learn from one another

ETA-China has been promoting the world-class tolerance analysis software 3DCS in China since 2009. With the increasing emphasis on tolerance analysis in the manufacturing industry, 3DCS has been widely used by automotive, aerospace, 3C product manufacturers and many universities.

Monte Carlo Simulation for Tolerance Analysis in Prefabrication and Offsite Construction

Monte Carlo Simulation for Tolerance Analysis in Prefabrication and Offsite Construction 

Understanding how analysis of prefabricated assemblies in construction makes for better modern buildings

Written by Chris Rausch, PhD Student, in conjunction with the University of Waterloo and the University of Toronto

     

Highlights

  • The AEC industry lacks comprehensive approaches for controlling geometry in offsite fabrication and assembly.
  • Assembly tolerances can accumulate to cause misalignment at key connection points.
  • 3-D tolerance behaviour can be predicted using Monte Carlo simulation, predefined process tolerances and assembly sequence.
  • Statistical distributions for misalignments are generated and used to quantify rework risk.
  • Tolerance simulation can be used to analyse alternative fabrication and assembly processes to reduce the risk of rework.

Avoid Double Work with the Digital Twin and GD&T

Digital Twins Help Avoid Double Work

(and Waste)

Many businesses are still clinging to 2D drawings or a combination of 2D and 3D CAD renderings. Although 2D drawings may feel comfortable to use, they can actually cause problems throughout the design and manufacturing process. For example, any change made to a 2D drawing has to be manually applied. Unfortunately, drawings can be modified at any point along the workflow, leading to problems with the resulting manufactured part (and eventually, the entire system).

 2D Drawings are very useful tools, but hard to keep properly updated and communicate downstream

How is Excel Failing Your Tolerance Stack Ups? Now ON-DEMAND

[Webinar] How is Excel Failing Your Tolerance Stack Ups

Understanding the difference between 1D vs 2D vs 3D vs Worst Case Tolerance Analysis, and how you may become misled.

Tolerance Analysis can be a simple function. Using RSS and Excel, tolerances can be calculated as a stack-up to determine the range of variation. However, as soon as this method is used for real parts in an assembly, this method begins to lose its validity. Incorporating the variation from 3 dimensional effects can make the math extremely difficult and hard to reproduce quickly, leaving out variation that can cause expensive problems during manufacturing.

1D vs 2D vs 3D Tolerance Analysis, How is Excel Failing your Tolerance Stack Ups? [Webinar]

1D vs 2D vs 3D Tolerance Analysis Explained

Excel Stack-Ups do not include influences from 3D part associations, nor does it include process variation, that can greatly impact a design causing high costs to correct in scrap, rework and recalls.
