3DCS Design Variation Modeler - DVM

Easy-to-Use 3D Tolerance Stack Simulation

Equation-Based Simulation

3DCS DVM (Design Variation Modeler) is an entry-level equation-based 3D assembly GD&T prediction tool integrated in the major CAD Platforms.  

DVM is intended for components assembled in one station with planar and axial locating features.

  • Learn quickly
  • Get answers fast
  • Use irregularly without retraining

Benefits of DVM vs. Excel Stacks

  • Take into account the 3D effect
  • Create (reusable) virtual prototype
  • Run what-if studies
  • Reduce calculation time
  • One single source of answers (single model vs spreadsheets)
  • Quick change management – no need to rebuild with each change
  • Add new Measurements without creating new tolerance stacks
  • Reduce manufacturing risk
  • Reduce manufacturing costs

Integrated Solution

Available Fully Integrated into CATIA, 3DEXPERIENCE, NX, CREO, and SOLIDWORKS

Also available as a Stand-Alone software for any CAD Platform

  • Save inside the CAD model – easy model file management
  • Follows the model – easily integrates with PLM Systems (Teamcenter, Windchill, Enovia, 3DEXPERIENCE)
  • Work in the same environment – no translations or exports
  • Use GD&T & Product Manufacturing Information PMI to Support Model Building

Easy to Learn and Use 3D Analysis 

Easy to Learn and Use 3D Analysis that provides more accuracy than 1D Excel Stacks

  • Easy to learn and use 3D Analysis 
  • Faster and more accurate than a 1D stack
  • Integrated into CAD - Design change & PMI 
  • Scalable solution to 3DCS Variation Analyst
  • Available to a broader team

Part of 3DCS Suite 

3DCS DVM is part of the DCS Scalable Solution. 

This tool provides broad access to tolerance analysis for your organization, allowing for fast stacks to be calculated and tolerance models to be made quickly, with little training. 

If complex processes or difficult conditions exist in your product, you can flag your models and pass them to a Specialist to use 3DCS Variation Analyst, the advanced analysis version for high complexity analysis.

3DCS DVM Key Features

How does 3DCS DVM help you reduce lead times, scrap, and rework?

Quick Build with PMI

Extract Product Manufacturing Information PMI - GD&T - and Joints and Constraints from your CAD model to instantly create a tolerance simulation. Use DVM's moves, measures, and tolerances to complete the model and get additional information. 

Value:

  • Build models faster with PMI
  • Streamline processes utilizing Model-Based Definition
  • Reduce reauthoring of information by making the CAD model the single source of information
  • Combine with DVM's inbuilt tolerances, moves, and measures

Immediate Results

Equation-based analysis provides instant results from your tolerance stack up simulation. 

Value:

  • Get immediate results from your analysis
  • Make changes and get your results right away
  • Easy to understand outputs help to make decisions quickly

Update without Rebuilding

Change, update, and alter your design & model, and get immediate results without having to rebuild or remake the model. 

Value:

  • Part and design changes can be updates with a single button click
  • Changes to tolerances, GD&T, assembly, and part geometry can be quickly incorporated without rebuilding
  • Allows for fast iterative design changes to determine the impact of alterations and variants
  • Add new measures without creating a new tolerance stack

Root Cause Variation

Find the sources of variation and begin reducing your risk of failure. 

Value:

  • Find primary source of variation issues from either tolerances or assembly process
  • Make changes and determine the affect of variation
  • Use iterative changes to create the optimal design for maximum quality and minimum cost

True 3D Stacks

Determine variation from 3-dimensional influences without timely modeling. 

Value:

  • Incorporates 3-dimensional analysis 
  • Provides a much more accurate picture than 1D Stacks
  • Create your simulations and stacks faster than doing the same analysis in Excel
