Or collapse them into an offset operator…

Actually I’ll have to look into that.

Moving points by commands themselves aren’t that bad, the problem is that
when you deal with a few thousand vertices the speed and stability
difference between manipulating an array and moving points starts being in
the tens of folds

Like raf says, you can use commands to shift points. Translate et al are
operations, meaning they go on the stack, meaning you don't have to freeze.
Remember to clean them up if there's a lot of them, though.

If you don’t want to freeze you’ll have to give up the OM for moving points
and do it by commands (baaaaad), OR write the manipulation in a scop, good
chance to give it a go Patrick :)

Hi Raffaele,

It's work good. But don't forget to FREEEEEEEZZZZE, before ! like you
written.

Thank you.

You want to get the selection, the object the selection is on and then get
the activeprimitive.geometry of it.

>From that you can get the points.positionarray, manipulate the array, and
then store the manipulated array back in the positionarray.

Should be said tho that you can only manipulate the positionarray in a
script if the object is frozen, if you need to keep the operators you’ll
have to write a scop to do the same job, with the undertow that SCOPs
manipulating partial selections of points need a cluster to relate to those
points (or the pointIDs hardcoded in a loop).

Here’s an example

set oRoot = application.activeproject.activescene.root

set oSelection = Application.Selection

set oPoints=oSelection(0)

if oPoints.Type = "pntSubComponent" Then

set oObj = oRoot.FindChild(oPoints.Name)

set oGeom = oObj.ActivePrimitive.Geometry

ArrPoints = oPoints.SubElements

aPositions = oGeom.Points.PositionArray

aIndices = oPoints.SubElements

for i = LBound( aIndices, 1 ) to UBound( aIndices, 1 )

ii = aIndices(i)

aPositions(0,ii) = aPositions(0,ii) +1

aPositions(1,ii) = aPositions(1,ii) +1

aPositions(2,ii) = aPositions(2,ii) +1

next

oGeom.Points.PositionArray = aPositions

end if

select points on a frozen object and run it, it will shift every point by
1,1,1

Hi all,

I select points on an object by tagging an d i need to GET (SRT info) and
SET to a new positions (SRT) on each points by script, of course.

Have you an suggestion ??
Thanks.
