LUA scripting: issue with visualizing slices in GUI

[quentin_schmidBRKQZ]

Hi I am trying to use a script to automate slicing. inspired by the example script, I wanted to display the obtained slices in the GUI using :

system:setloggingtooglwindow(true);
if tray == nil then
system:log(' tray is nil!');
else
local root = tray.root;

for mesh_index = 0, root.meshcount - 1 do

local mesh = root:getmesh(mesh_index);
local luamesh = mesh.mesh;
local MeshName = mesh.name;
local matrix = mesh.matrix;
newMesh = luamesh:dupe();
local matrix = mesh.matrix;
newMesh:applymatrix(matrix);
local outbox = newMesh:calcoutbox();
local Layersize = 0.03;

local FromZ = outbox.minz;
local ToZ = outbox.maxz;
system:log('Upper BB limit is :' .. ToZ);
local CreateInMemory = true;
local filename = PATH .. MeshName .. tostring("_") .. tostring(mesh_index) .. '.sli';
slice = system:slicemesh(newMesh, Layersize, FromZ, ToZ, CreateInMemory);
system:addslicetotree(slice);
--(0: USF, 1: CLI, 2: SLI, 3: CLS, 4: SLC);
slice:savetofile(filename, 2, Layersize, FromZ, ToZ);

end;
end;

but I do not see anything, even though the slicing seem to work well when I open the file that I exported.

Thanks,

Quentin

Hello, @quentin_schmidBRKQZ,

Welcome to the Netfabb forum!

This is not possible as this would cross between scopes which the current Lua implementation does not allow.

For more details see this remark in the online help: https://help.autodesk.com/view/NETF/2025/ENU/?guid=NETF-LUA-LUA#api-scopes

As well as this thread where the same limitation was hit by another user: https://forums.autodesk.com/t5/netfabb-forum/script10-slicebuildplatform/m-p/11709664#M2405

Kind regards,
