1DCS 

1DCS is a World Class Linear Tolerance Analysis Tool that allows users to quickly develop and analyze various design objectives through the comparison of different tolerance scenarios.  1DCS offers users the ability to allocate tolerances to determine  the component capability required to meet overall assembly objectives (Roll-down), as well as determine the overall assembly variation based on actual tolerance capability (Roll-Up).  Studies testing Alternative Tolerancing Schemes and Assembly Sequences can help to identify the most "Robust" Design & Manufacturing Alternatives.

1DCS has a simple, graphical user interface that anyone can use.   Because no "programming" is required, engineers and designers can learn how to use this simple tool with a minimal amount of effort, but the output is invaluable.

Graphical User Interface:
1DCS is a Graphics-Based Package.  It employs a Graphical User Interface that allows for rapid development of tolerance studies, and requires a minimal amount of effort to learn.  Anyone who is familiar with a Microsoft Windows-based computer can perform tolerance analysis.

Predict & Display Assembly Variation:
Because 1DCS is Graphical in nature, The assembly and assembly sequence are displayed in a descriptive tree and histograms are used to graphically display the assembly tolerance, with red bars indicating the out of spec condition.

Complete Statistical Data:
1DCS uses a Random Number Generator to assign a value for each tolerance during each and every Simulated Build.  The simulation method can be selected from Monte Carlo, RSS, or Worst-Case, and users can import actual part data for even more accurate results.   The Distribution Type for each Tolerance can be select from a list of distribution-types or a best-fit curve can be calculated to match your data.  The output of each simulation comes in the form of Complete Statistical Results that include, Standard Deviation, % Out of Spec, Tolerance Ranges, and a Histogram that graphically displays the distribution for each measurement in the model.

Complete Assembly Diagrams:
Determining the best assembly sequence is paramount to simultaneous engineering.  To make that possible, 1DCS uses a simple assembly tree to display the relationships between parts and sub-assemblies.  Each part, sub-assembly, and fixture is identified in the correct assembly sequence and each element in the assembly tree is assigned it's associated tolerance.  This tree serves as a quick and user-friendly interface through which the user can perform his or her studies.

Automatic Report Formatting & Database Connectivity:
Reporting the output of tolerance studies is simple and thorough in 1DCS.  Reports are created automatically, with the touch of a button.  And the statistical output can also be directed to an ODBC database just as easily.
