What does a reference dimension look like?

A Reference Dimension is a dimension given to any features that are just for reference – or visualization purposes. These are called out on a drawing using parenthesis (i.e., 5.125). It also could be a dimension that is described on another drawing or elsewhere. Either way, the dimension does not get inspected.

What is a reference dimension in Solidworks?

Reference dimensions show measurements of the model, but they do not drive the model and you cannot change their values. However, when you change the model, the reference dimensions update accordingly. Reference dimensions are enclosed in parentheses by default (except ordinate dimensions).

How do you show reference dimensions in Solidworks drawing?

To add a reference dimension:

  1. Click Smart Dimension. (Dimensions/Relations toolbar) or click Tools > Dimensions > Smart.
  2. In a drawing view, click the items you want to dimension. You can dimension to a silhouette edge.
  3. Use rapid dimensioning to place evenly spaced dimensions.

What is a baseline dimension?

A baseline dimension is a group design object. It allows for the dimensioning of a linear distance of a collection of references, relative to a single base reference. The first point chosen is the ‘base’. All subsequent points are relative to this first point.
