Sure, numerical manipulation of screen-space coordinates in the operator redo panel is an ad-hoc way to achieve what more interactive direct manipulation could offer to tune the line/rectangle specified in the first attempt. A rubber band in the form of a line/rectangle for redo would be nicer. > Being able to enter in mouse coords exactly doesnt help much with > either of these since screen coords don't map to camera view coords. Oh I see, that's exactly the rationale behind the removal of the parameters from the operator redo panel, right? Admittedly overlooking that point, my example of a 500-by-500 render border was irrelevant. -- KAJIYAMA, Tamito <rd6t-k...@asahi-net.or.jp> On 26/05/2014 09:01, Campbell Barton wrote: > On Sun, May 25, 2014 at 11:24 PM, Tamito KAJIYAMA > <rd6t-k...@asahi-net.or.jp> wrote: >> Mouse coordinates are useful for quick and rough specification of a >> line/rectangle by clicking two points in the view port.
