we jumped from nx8.5 to 10 and this may seem like a naïve question but what happened to dragging dimensions in real-time
the only thing I found close to it is opening the sketch in task env and editing the sketch parameters. I miss it-where is it
With the sketch active select Menu-Edit-Sketch Parameters this displays the Sketch Parameters dialog and the drag bar.
I'm sure there is an Icon for this you can add to you sketch toolbar.
