An Overview of Dimxpert Model.


DimXpert is part of the SWIFT (SOLIDWORKS Intelligent Feature Technology) functionality found in SOLIDWORKS. More than just dimensioning, DimXpert provides an environment to add dimensions, both manually and automatically, to your designs complete with tolerancing.

DimXpert follows ASME Y14.41-2003 and ISO 16792:2006. Even if you do not typically apply GD&T you can still use the Plus / Minus Tolerancing, represented in many standard (common) formats.

Getting Started (Manual Dimensions)

Both the Tree and the ribbon contain tools for working with DimXpert.



DimXpert works with Mechanical features, which are different than the features you add to your models. What this means is that DimXpert works just as well with an imported STEP file (with no intelligence) as it does with a SOLIDWORKS model you built from the ground up.  DimXpert was designed for manufacturing detailing, as it recognizes common manufacturing features like bosses, fillets, chamfers, holes, slots, pockets, and on and on. It understands how certain features are created, and dimensions accordingly. So whether the feature is prismatic (mill, drill, etc.) or turned (lathe) you will get the dimensioning style and layout you need.

To manually add dimensions and annotations use a combination of features. The thing I love the most about this is that you don’t select points, lines, and centers… you actually pick features! Think about it this way… you want to dimensionally locate a hole, with DimXpert you select the hole and the face you want to dimension the hole from.

There are three dimension features: Location Dimension, Size Dimension, and Basic Dimension.

Location Dimensions are used to locate features, both linearly and angular. Use Size Dimensions to extract the size information of the feature. Both work with most features, Location Dimensions do not work with a few types including surfaces, fillets, chamfers, and pockets.

With Location Dimensions you have the following options:

  • Linear dimensions are created between parallel planes/faces/axis/edges, between two points, between a point and a plane/axis/edge, and axis/edges that are non-parallel and non-intersecting.
  • Angular dimensions are created between two non-parallel planes/faces/edges
  • Additional options include Points and the various Plane features. Edges are only available in certain situations.
