Like all CAD programs, SolidWorks allows you to dimension the parts you create. Parts do not have to be dimensioned, but when you are making accurate drawings or are interested in mating parts, dimensions are extremely important. Luckily, SolidWorks makes it very easy to add and change dimensions. This tutorial will use "link3slide.SLDPRT" from the parts.zip archive. You can use this tutorial for any part though.


-         a circle radius or diameter

-         a line

-         an arc

-         a fillet/chamfer

-         distance between two points

-         distance between a line and a point



You are now ready to try Dimensioning Exercise 1

● If you notice that the dimension tool is not working or working erratically, you can always hit escape to unselect the dimension tool and start over again. This usually fixes any problem.

● If you mess up badly, you can always edit->undo. Likewise, if you want to go back to a certain point, you can use the undo list to see your undo options
