Why are the dimensions on my sketches not displaying?
There are 2 likely causes of this problem, the first one is that your Application options need to be changed to show the dimension text in a larger font. To do this from inside of Inventor, click on Tools, then Application options. On the Sketch tab, set your "Constraint & DOF symbol scale" to 1 If this doesn't work, then the second thing to investigate is your graphics driver. Your Graphics driver is more than likely in need of an update
