here is the task setup:
delete objects
gc()
(
mesh_attach = meshop.attach
fn fastAttach meshes =
(
k = 1
while meshes.count > 1 do
(
k += 1
mesh_attach meshes[k-1] meshes[k]
deleteItem meshes k
if k >= meshes.count do k = 1
)
meshes[1]
)
size = [32,32]
global poly = editable_mesh()
meshes = #()
for y=0 to size.y-1 do for x=0 to size.x-1 do
(
m = copy (createinstance plane width:1 length:1 widthsegs:2 lengthsegs:2).mesh
meshop.movevert m #all [x*1.2, y*1.2,0]
append meshes m
)
poly.mesh = fastAttach meshes
converttopoly poly
update poly
select poly
)
the challenge is –
Design quick and convenient UI to Grow and Shrink element selection for this poly node.

Because the most interesting of this challenge is User Interface solution let’s make all more simpler. Do Growing and Shrinking by face index (not position!).

Had some play for fun. *Still would not know how to grow

My next step would have been change face selection on element spinner
But had to do some work
Jun 11, 2017 3:56 am
Or I guess select element by face spinner

Now for the impossible part grow by face ID and not by position. *Will it always be this object from your code?
Hmmm…

Ok, I think I have solved it
