points transformation by script commands

Once you are done manipulating the aindices array all you need to do is

oGeom.Points.PositionArray = aPositions

and that will force the new array (the one with your manipulation in it)
into the objects geometry, doing effectively what you wanted to do.

Again you only have to be careful that the object is frozen, or trying to
write into the position array will result in an illegal operation.

Good luck :)

Raffaele,

Great, i can get the positions on each points inside the "for next" loop.

My goal is to modify the positions of the points.

An exemple :

- some points position can be 10.05897423 or 5.693145 or 7.00026

- my goal is to modify their position like this : 10.05 or 5.69 or 7.00

- have a choice to keep 2 (ie) number after the dot...

with your help i've made that, but I don't know how to modify the posXYZ of
the point.

-- ---- ---- ---- ---- ---- --

set oRoot = application.activeproject.activescene.root
set oSelection = Application.Selection
set oPoints=oSelection(0)

ApresLaVirgule = InputBox ("Nbs de chiffre apès la virgule :","XSI
Script","2")
If ApresLaVirgule <> "" then

if oPoints.Type = ".....

.................oPoints.SubElements

for i = LBound( aIndices, 1 ) to UBound( aIndices, 1 )
ii = aIndices(i)
for axis=0 to 2

pos = aPositions(axis,ii)
LaVirgule=inStr(1,pos,".",0)
aPositions(axis,ii) = left(pos,ApresLaVirgule +
LaVirgule)

Next

....

-- ---- ---- ---- ---- ---- --

Hope that i'm clear

Thank

Patrick
