Dimensioning with SolidWorks - Demo Although most demos are implemented with word documents, this demo employs slides so that more details can be shown to the students as the drawing is constructed. Part 1 Since Dimensioning is one of the more difficult concepts introduced in 1182, the resulting dimensioned file produced by this instructor led DEMO is not recommended as an optional in class assignment since the student will benefit by doing the in class assignment on the EEIC website on their own.

Dimensioning in SolidWorks Basic Dimensioning Dimensioning is used to define an object so that it could be manufactured and must: Define the overall size of the part in all 3 dimensions. Define the size and location of the features of the part in all 3 dimensions. Rev: 20140114, AJP Dimensioning in SolidWorks

Baseline versus Chain Dimensioning There are many ways to use dimensions to locate features. Chain Baseline (Both techniques are acceptable, however baseline dimensions are preferred.) Chain Dimensioning Baseline Dimensioning Rev: 20140114, AJP Dimensioning in SolidWorks

SolidWorks: Adding Dimensions, Center Marks and Center Lines Dimensions can be added using the “Smart Dimension” feature Notes can be added to reduce the number of dimensions by stating symmetry or identifying fillet radii Note that sometimes the Isometric needs to be re-scaled to allow adequate drawing space which requires a NOTE. Notes can be used to describe Symmetry or radii of curvature, etc. Rev: 2014-07-13 - RCB Dimensioning in SolidWorks

Size and Locate the Other Features Note that the following Dimensioning Guidelines have been followed: Dimensions are located in the "Characteristic View" Positive cylinders are dimensioned where they appear as rectangles Negative cylinders are dimensioned where they appear as circles Dimensions are generally located between Orthographic Views Object is not OVER DIMENSIONED (no more dimensions allowed!) Note that since dimensioning is one of the more difficult exercises, it is NOT recommended that the completed dimensioned drawing be optionally submitted for the in-class assignment. The provided in-class assignment provides the needed student practice in dimensioning. Rev: 2015-05-20 - RCB Dimensioning in SolidWorks
