I would love to be able to enter simple formulas in sketch dimensions. Like “=d2 / 2”, or “=d2”, or “=d2 - 10”, where d2 is an existing dimension. Doesn’t need to be super complicated math parsing.
This would help to automate some sketches where dimensions may change (such as connector positions when the size of an enclosure changes).

This will come with History Based Parametric Modeling. Try it if you haven’t yet, though this specific feature isn’t yet implemented.

Had this been implemented yet? Where is it on the timeline?
