    To use an equation in a dimension, you still use the dimension tool but instead of entering in the value, enter in the equation that you want to use.

    Here is an example using a variable that was created earlier:

    @robert_morris  Thanks so far, but I would like to see something like this https://www.onshape.com/cad-blog/whats-new-10-13-2015. Just did not find it before.

    @brucebartlett but why You do not like official video? I posted this quaestion only because could not find it. Suppose there is nothing better than official videos. :)

    @arturs_zipris, yes the video is good, just watched it, or part of it but I think though a picture may be a quicker to grasp the concepts.

    Good tip for creating a bunch of variables is to rollback whole feature list and use shift+enter when accepting > that will immediately continue with another new variable.

    Remember to think names twice, at the moment you can't change without rewriting all equations.

    Shouldn't this be possible? Is there a workaround? I want to have 1 dimensions (width) as my "driving" dimension. If that value changes down the road, all the geometry will update based on the functions.

    @jeremie_bertin
    Looks like you probably have a units error -- if you get rid of the parenthises (just #Width + 1/8 in) it should work.
