3DCS Variation Analyst


Today's fast paced product market has shorter lifecycles and tighter budgetary concerns. Tolerance analysis software provides an ideal solution to reduce the number of crucial steps needed to optimize a product at the design step itself. 3DCS Variation Analyst is the world's most used tolerance analysis software that is fully integrated into NX/ CATIA V5/ Creo and CAD Neutral Multi-CAD. 3DCS Variation Analyst is designed to use a consistent format and set of mathematical formulae that create reliable results, enabling engineers to gain a complete insight into their design. The software empowers design engineers to control variation and optimize their designs to account for inherent process and part variation, which in turn reduces non-conformance, scrap, rework and other associated costs.

About 3DCS Variation Analyst

DCS - Spec Studies Show Variation

Used by the world’s leading manufacturing OEM’s to reduce the cost of quality, 3DCS Variation Analyst comes in two flavours:

1) 3DCS Variation Analyst (NX / CAA V5 or Creo Based) is an integrated solution for NX / CATIA V5 or Creo. Since it is an integrated solution, users can not only activate 3DCS workbenches from within the modelling solution, they can use many of its inbuilt functionality to support their modelling.

2) 3DCS Variation Analyst Multi-CAD is a standalone CAD neutral software system. It is used for modeling variation that is caused by part tolerances as well as manufacturing and assembly processes. Using Transmagic conversion software, 3DCS Multi-CAD works with native CAD files (.prt, CAD product, etc), STEP, IGES and JT files. It thus provides a single, CAD neutral platform for designing products in an optimal manner.

How 3DCS Variation Analyst Works - Model Part and Process Variation

3DCS Variation Analyst Multi-CAD

The software utilizes three methods of simulation to highlight the sources of variation and to identify the potential build issues of the product. Since the software accurately models the product build process, the user can accurately simulate in a virtual environment. In other words, the software essentially creates digital prototypes to test and validate design objectives of the product.

Why use 3DCS Variation Analyst?

Why use 3DCS Variation Analyst

Since the software allows a design engineer to simulate products in a digital environment, they are able to gain new insights into the product design and account for variation in key areas. This reduces rework, non-conformance and scrap at final assembly. Moreover, specifications that are less critical can be relaxed, increasing tolerances and allowing the use of less expensive manufacturing processes. This in turn reduces the product manufacturing costs without sacrificing its overall quality.

3DCS software has automatic report generation for fast, effective communication of analysis results, and easy collaboration with peers and managers.
