slice script

Submitted by titane357 on Tue, 2010-08-10 10:43

Hello

I try to make a script to slice selected polys at equal distances in between two picked points.

Here is the in progress (in not progressing state) script.

Don't work.... If somebody can help. :-)

#universe

pta = pickpoint snap:#3d
ptb = pickpoint snap:#3d rubberBand:pta

try destroyDialog rlslice catch()
global rlslice = rollout rlslice "Slice"
(
button butconnect "GO" pos:[2,2]
spinner spX "X " width:60 range:[2,100,3] type:#integer pos:[55,5]
on butconnect pressed do
(
ptd = ( pta - ptb )
for i=0 to (spX.value) do
(
inc = (ptd/(spX.value+2))
ppp = (inc * i) + pta

Point pos: ppp
$.EditablePoly.slice [1,0,0] ppp flaggedFacesOnly:on
)
)
)
createDialog rlslice 160 50

Ah, now it makes totall sense. Thanks Miauu :)

Question: What do you need to change in the code so that it affects the current slice modifier instead of adding a new one?

Kind regards

Wonderful!
Works perfect :)

I saved both of them and will at some point look how it works to create a scripted plugin so that I use the first one (that adds a new modifier) as an option to the regular Slice.

Kind regards

How is this last script supposed to work?
Made a quick try, but achieved nothing.

hello anubis, nice to see

hello anubis, nice to see you.
I test with "local" but don't work....
I have another version where I substract object position, it was ok but slices planes wasn't rotated within the object...

(
local savesnap=snapMode.active
snapMode.active=true

in coordsys local pta = pickpoint snap:#3d
in coordsys local ptb = pickpoint snap:#3d rubberBand:pta
ptd = ( ptb - pta )
nptd = normalize ptd
na = nptd[1]
nb = nptd[2]
nc = nptd[3]
try destroyDialog rlslice catch()
global rlslice = rollout rlslice "Slice"
(
button butconnect "GO" pos:[2,2]
spinner spX "X " width:60 range:[2,100,3] type:#integer pos:[55,5]
on butconnect pressed do
(
for i=1 to (spX.value-1) do
(
inc = (ptd/(spX.value))
ppp = (inc * i) + pta
in coordsys local Point pos: ppp
in coordsys local $.EditablePoly.slice [na,nb,nc] ppp flaggedFacesOnly:on

hello again, Here is my

hello again,

Here is my script, but I don't know how to convert in local syst (because slice is in local sys )
anybody help ?

pta = pickpoint snap:#3d
ptb = pickpoint snap:#3d rubberBand:pta
ptd = ( ptb - pta )
nptd = normalize ptd
na = nptd[1]
nb = nptd[2]
nc = nptd[3]
try destroyDialog rlslice catch()
global rlslice = rollout rlslice "Slice"
(
button butconnect "GO" pos:[2,2]
spinner spX "X " width:60 range:[2,100,3] type:#integer pos:[55,5]
on butconnect pressed do
(
for i=1 to (spX.value-1) do
(
inc = (ptd/(spX.value))
ppp = (inc * i) + pta
--Point pos: ppp
$.EditablePoly.slice [na,nb,nc] ppp flaggedFacesOnly:on
)
)

createDialog rlslice 160 50
