Re: Provide a simple measurement tool
The advantage of % is you can hit F6 and the sphere won't get added to your
object. If you don't like transparent grey you can override it with color.
E.g.color("grey") %.

HI Nophead,
I used your suggestions wrt the alt and up/down arrows, (and the norm)
and it makes the process far more usable, and I've used the % too, but in
this case, it was a bit distracting in the grey, due to transparency, to
locate the spheres where I wanted them, and for the final positioning I
removed the %, and lived with the possibly slightly slower rendering in
this example.
Having revisited it, I find that rendering times for moving a sphere
around in this particular stl file, seem to be very similar, between 0,036
and 0.079 in both cases (i.e. with and without %.) - removing the text
lines, rendering (based on half a dozen or so alt/arrows) lies between
0.038 and 0.043 for the yellow, and 0.026 and 0.042 for the transparent,
which explains why I noticed no difference in speed of rendering this
particular file.

Looks like you are using # rather than %. # will highlight pink but still
be included in the model. % will be transparent grey and not included in
the model.

If you use the background modifier (%) for your measurement object, it

be able to load from cache and not need to be re-calculated. Sometimes
preview is still slower than you'd like when nothing has changed if the
model is particularly complex, but it will always be faster if the program
isn't trying to do boolean operations involving any of the parts you've
modified since the last preview.

test object painfully slow at times.
