Re: Help

Solidworks does have a "Dimensions" tool. You might try using that.

Re: Help

It's a scale drawing, print it out and measure the size of things, and use a protractor to find the angles.

Re: Help

If you have the model, then I would use the Measure tool:

Hold the control key down. Select the bottom flat face. Select the top flat face. and the normal distance will appear in the lower right corner of the graphics windows.

In the Evaluate tab, select the Measure tool for more options to measure angles and calculate x-y-z dimensions on the fly.

If you are in the drawing, there are some automatic dimensioning tools that can be very helpful. We usually don't stress these techiques in education because we want you to learn how to dimension according to a standard - but "DimXpert" can save you lots of time. Assuming you are using 2010, insert your views into a drawing. Select the small black expand arrow from the Smart Dimension tool from the Annotation toolbar. Select DimXpert option. Now select a vertex. This is your datum. Select different geometry in the view, such as a hole or edge. SolidWorks will insert horizontal, vertical and diameter dimensions automatically referencing the datum.


Marie

The roller axis should be 45 degrees from the plane of the wheel.

If you want a "bump-free" mecanum wheel, the contour of the rollers is important. Design help for the roller profile can be found here: http://www.chiefdelphi.com/media/papers/2390

Also the rollers should be long enough so that there is a slight overlap as one roller transitions to the next as the wheel is turning.
