Hi Burr, thanks for the video description that helps clear it up.

So yeah you don't want any "perp/perp" type of thing for your case, so that CrvDeviation tool in Rhino will not work for this case.

Doing a set of y-axis aligned lines like you showed there will work but the accuracy will be limited to whatever density of lines you used. But you can probably do a pretty large number of them just in the general area where you know the spot is at.

Then doing a script that just selects the longest curve from all existing ones in the model is definitely possible without much fuss - here's one that you can set up on a shortcut key:

script: /* select longest curve */ var curves = moi.geometryDatabase.getObjects().getCurves(); var maxlen = -1; var maxcrv = null; for ( var i = 0; i < curves.length; ++i ) { var crv = curves.item(i); if ( crv.hidden || crv.locked ) { continue; } var thislen = crv.getLength(); if ( thislen> maxlen ) { maxlen = thislen; maxcrv = crv; } } if ( maxcrv != null ) maxcrv.selected = true;

That will look through all curves that are not hidden or locked, it does not only look at lines, so if you have some curves that you don't want to have considered (like the original ones that you are measuring between) lock or hide those before running the script.

Hope that helps!

so you have now 2 scripts ;)

Hi Michael,
Thanks for the help.

Frenchy,
Thanks for looking in... Yes the curves are all planar and the sketchup script does the measurment too, 2... :)

@Michael
Does it possible to have the smallest curve ?
I have made some try without success but a little headache ;)
At first view some inverse sign and other trivial changements but not so easy for me :D

Added the biggest :)

Ps What happen if there are 2 biggest equal?
Seem the first created is selected :)

Pss And it's a curious workflow : nothing must be selected before lauch the script!
I have make many try before find it by hasard :D

Hi Pilou,

> Does it possible to have the smallest curve ?

Yup, this script will select the smallest curve instead:

script: /* select shortest curve */ var curves = moi.geometryDatabase.getObjects().getCurves(); var minlen = 1e100; var mincrv = null; for ( var i = 0; i < curves.length; ++i ) { var crv = curves.item(i); if ( crv.hidden || crv.locked ) { continue; } var thislen = crv.getLength(); if ( thislen < minlen ) { minlen = thislen; mincrv = crv; } } if ( mincrv != null ) mincrv.selected = true;


> Ps What happen if there are 2 biggest equal?

Yup, that's correct.

Yup, it adds the shortest or longest one to the selection without disturbing other already selected objects. That allows for more flexibility - for example if you want to select both the shortest and the longest curve you can start with nothing selected and then run both of those scripts and you'll then have that selection at the end. If each script cleared the selection first then it wouldn't be possible to do that anymore.

But if you do want everything else to be deselected, it's possible to do that by adding a call to moi.geometryDatabase.deselectAll(); at the start of the scripts.

Well well all is clear now!
So 2 more little scripts who can be useful for tricky things!

var minlen = 1e100; that was this that I have missed !
Near the infinite of the number of stars ;)
