2012 has added many shortcuts that allow us to get our jobs done faster and more efficiently. Here is a new function that you may find useful if you create a lot of revolved features. 2012 now gives us the function to add multiple radial or diametric dimensions at one time without having to select the centerline every time. There is nothing special to activiate this function. Dimenison between a centerline and a line or point. Place your dimension to create either a radial dimension or a diametric dimension. Now just select the next line or point you want to dimension. SOLIDWORKS will automatically use the same centerline as the previous dimension. Your pointer will also change to for a diameter dimension.
