I have some object and want to transform to some absolute length …
(The gumball scale handles are convenient since they are in the model space and don’t require diverting into dropdowns or the command line).
… so suppose in this case we want a new length of 355 units - the only way I’ve managed to discover to achieve this explicitly is to append the desired length with the units (to force absolute) and divide by two (or the length becomes 2x because scaling is bidirectional) :
(although the “mm” needs to be in the divisor - which I always seem to forget the first time)
Is this the best way to achieve this action - or is there another less awkward route to this end?
How about using
Scale1D with a desired length instead of a second reference point?
Hi Brian -
It all depends on the specific situation, but you can move the gumball to a position at one of the ends, from which you’d be able to drop the division.
(and the same applies to the
Thanks for the tips @diff-arch and @wim - so it looks like
Scale1D is the closest to what I was thinking, (in terms of entering a number that transforms directly to that value in units). I think that will be most useful in quickly squaring-up elements in a multi part design.
From what I can tell relocating the gumball fixes the point/plane origin of the transformation - but - (in the case of some simple box-like object having extents that equal the bounding box) entering the scale-handle in units still yields a result that is 2x the length, i.e. :
Always great to get to explore the various approaches, definitely find that it helps in enhancing my grasp of how Rhino “thinks” about geometries. I wonder if this imagined “direct editing” approach is something that the new Constraints features will enable.
as others pointed out,
is the best solution i think
please notice, that scale1d does not only accept scalefactor, but also target length:
Base point - pick first dimension point
Scale factor or reference point - pick second point
Second reference point - enter number: the target number !!
