hi
i always loose the subtract object when boolean differnce
ex:assemble 2 objects with bolt , the bolt is subtract object (electrod)
is it possible to have chek box to keep it

Use "Boolean Merge" you will have all combinaisons possible in the same time!
So you can choose all that you want to keep or delete ;)
Just Boolean Union after your choice if necessary :)

hi pilou
boolean merge will splite the bolt in pieces and i dont want to splite it

Have you a little image or file 3dm?

with boolean differnce the bolt is subtracting object and i want to keep it in good shape

OK: I see :)
Just Copy Move the Bolt on a straight axis by a certain distance "D"
Make the normal Diff :
Just Move come back the Bolt by the Distance D on the previus axis

Sure if exist a function "Diff Stay in place" that will be more easy but... ;)

Hi lyes,

I would just copy the bolts "edit~ copy" or "ctrl+c", make the boolean, then paste "edit~ paste" or "ctrl+v"

But do agree that an option to delete_input y/n would be good.

I second that. Copy paste is good but an option to keep the subtracted object would be very helpful.

Hi lyes, I have added this to the wishlist.

In the meantime using Copy / Paste like Steve suggested is probably the easiest.

Sorry if I am missing something (not unusual), but if you copy/paste an item, not moving it, and doing the boolean with the copy, would not the original still be in place?

Hi Brian, yes it would be - that is the way to currently achieve that.

What I would actually do would be to first do a copy, then do the boolean, then do the paste after the boolean is all done.

That way you don't have any time where there are 2 copies of an object stacked right directly on top of each other, which can make selection more difficult.

HI Brian you are not missing any thing but you are thausends miles away, hahaha
i added 2 lines to boolean diff script:copy and paste. and is working.

// config: norepeat

#include "GetObjects.js"

function DoDifference()
{
var objectpicker = moi.ui.createObjectPicker();
objectpicker.allowBReps();
objectpicker.allowCurves();

if ( !GetObjects( objectpicker ) )
return;

var baseobjects = objectpicker.objects;

moi.ui.beginUIUpdate();
moi.ui.hideUI( 'FirstSelectPrompt' );
moi.ui.showUI( 'SecondSelectPrompt' );
moi.ui.endUIUpdate();

if ( !GetObjects( objectpicker ) )
return;

moi.geometryDatabase.copyToClipboardCommand( objectpicker.objects );

var subtractobjects = objectpicker.objects;

var factory = moi.command.createFactory( 'booleandifference' );
factory.setInput( 0, baseobjects );
factory.setInput( 1, subtractobjects );

moi.geometryDatabase.pasteFromClipboard();

factory.commit();
}

DoDifference();

I think I would prefer to keep the simplicity of how it now works.
Especially the idea of withholding the paste until later! I had not given a though to any ability to do that!

And it's everyone usually being 2000miles away from me not the other way around---well I like to think so!

hi Brain sorrey its just a joke i dont know where you are ,
the clever one is michael im just using demo run out in 10 days

Hey! Mine was a joke also!(But you spelt my name correctly!!!!!!!)

With Michael/MoI and Andrew/3D Coat I am living in app heaven!
