: [dim-ek-spurt]-noun. SWIFT DrivenA means to apply dimensions and tolerances to a part model basedon the ANSI Y14.5 and Y14.41 GD&T standard or the equivalent ISOstandards.- ANSI Y14.5 and ASMEY14.41- ISO 1101 and 16792 (based on ANSI/ASME standards)
True Power of DimXpert
Different Than Model Creation
Modeling - Uses dimensions to establishdesign intent
Drawings - Uses models for manufacturingand Inspection
DimXpert: Benefits
No need for expert status on GD&T in order to producecompliant dimension/tolerance scheme.GD&T can produce lower manufacturing costs by allowinglooser tolerances and reduce assembly fit problems.Fewer errors are generated and consistency is maintainedusing settings for plus/minus and GD&T in the options page,
DimXpert: Benefits
3D Models are fully annotated and can be viewed with EDrawings.Creation of 2D drawings is faster and easier utilizing DimXpertdimensions.

DimXpert: BenefitsQuickly identify under or over toleranced parts graphically.Dimensions can be automatically analyzed for tolerance stack using TolAnalyst.
