My whole standard assembly is driven by equations, to make it quicker for amendments when customer require special order. I can change entire shape using just 3 main dimensions (height - somewhere on side, length & width on top panel). However size of the drawer box can be only from a range (e.g. 239, 339, 439, 539mm width and also the height is changing: 90mm for first two, 140mm for bigger). I know how to create a Design Table in a SW part and how to use a table (in Excel) for ranges). The thing I don't know is how to (is it possible) drive DT by equations in assembly. If my drawer front width is for example between 261mm-360mm I want the width of my drawer box to be 239mm. In the range of 361-460: 339mm and so on...

Kind Regards

P.S.

Before posting I've done some research on the forum. This thread [https://forum.solidworks.com/thread/14544] is really good, but not exactly what I'm trying to achieve.
