"Smart" dimensions control
igor_sekularac

Is it possible to control dimensions values in sketch mode with link values, equations, global variables, variables, etc ?
The simple example would be to link two (or more) dimensions with a math formula (equation) so once you change one all others change following the formula?
For now I couldn't find the way to do it, but as I am a new user it is probable that I just don't have the right knowledge how to operate in Onshape.
Thank for answers and tips.

You will need to define your variable before using it in a scetch. There is no on the fly linking like solidworks.
Global variables are doable with featurescript. But only readable in partstudios.5 -

OK, it is as I thought ...
It's a pity that there is no "on the fly linking" (like some other parametric CAD systems), as it is very powerful and elegant tool.
I just hope that it is not a decision but rather one of many things on Onshape's to do list and that we can reasonably hope to see it sooner rather than later.
Thanks for your replies.
