how can i get difference between parallel frames ?

Hi Tudor,

> how can i get difference between parallel frames ?

Do you mean the difference in the origin points between 2 coordinate frames?

That would be like this:

var dx = FrameB.origin.x - FrameA.origin.x;
var dy = FrameB.origin.y - FrameA.origin.y;
var dz = FrameB.origin.z - FrameA.origin.z;

between parallels - similar to distance of projection of 1 pt from 1 frame to another

Hi Tudor, sorry it's not clear to me what you're trying to do.

If it's something like transforming the coordinates of a point in global x,y,z coordinates into coordinates relative to a frame, that would be like this:

var local_x = frame.distancex( pt );
var local_y = frame.distancey( pt );
var local_z = frame.distancez( pt );

The .distancex, .distancey, and .distancez functions on a coordinate frame return the distance of a point in world coordinates along the x, y, or z axis direction planes of the frame.

If that's not it then I need a clearer description of what you're trying to do, it's hard to figure out what you're asking about if you don't provide some more details.

bool operations of standalone curves that have different frames but are parallel to each other (ex circle at 0 0 0 and another at 1 1 1) -> to apply a move to second group(for difference will be subtract objectgroup) & do the bool

Is this something that you're trying to script? Can you show an example of the input objects and the result you are trying to make?

scene browser - objects are named
there is a solution - to create laaaaarge plane - and second group of objects to drop a point on this plane(project), and apply a move
mb is another solution

another script that i'm trying to work on is trim a segment or cut a segment from a curve
the problem that i'm conflicting is that i have todo a separate object - commit and later choose from sepFactory
I dont know what objects are created after commiting, or how can I set a variable to them ! sepFactory.commit().lenght = 0
what's happening after a commit ?

Ok, if you have a solution what do you need? Is there a question you have about this?

Hi Tudor,

re:

A .commit() is expected to be the last thing that is called on a factory, it is a signal to MoI that the work being done for the factory with updating different inputs is all finished.

If you want to get the objects that will be generated, you can instead call .update() and then .getCreatedObjects(). Or it is also possible to call .calculate() which will generate the result and return it as an object list without adding it in to the geometry database like usually happens in regular commands with .update()/.commit()/.cancel() .

All these Scripts (?) are they on a same place ? (Sites...)

thanks ! found also older posts by u'r recommendations
Trim hotkeys
t - trim add point
s - trim single segment (~ if u click wrong object it will delete that object -> there are no restriction to object selection)

single person trying to understand moi in depth - yes
mb later will open a git for scripts
don't like multiple theme option

Thanks for the infos!

i'm messing with bool operations difference operations to see all the states for curves
so ~ there's a glitch
on a shape like this with keep objects will delete 'baseobjects'

Hi Tudor, yes the curve booleans can get confused if you do a boolean between an open curve and a closed curve like that.

You can do an open curves as the base object and a closed curve as the cutter but a closed curve as the base object and an open curve as the cutter will tend to make some weird results. I would recommend to avoid using that combination.

Hi Michael !

I have a dream ))
Editpoints manipulation in 3dSpace if not snapped-> dragging -> http://moi3d.com/forum/index.php?webtag=MOI&msg=8665.117
toogle option
1. accordingly to the 3d view drag should change grid orientation : xy,xz,yz based on pickedpoint drag start position (similar to http://moi3d.com/forum/index.php?webtag=MOI&msg=8665.141)
2. view frame moi.ui.getActiveViewport().targetFrame

I've tried move command - but it requires to many actions for manipulation (for each -> select, move, axis or frame, drag)
this way we won't be snapped to orto views

about
http://moi3d.com/forum/index.php?webtag=MOI&msg=8665.142 - only on init - we can cancel align and do new one if camera changes
