First Checks
FILE TYPE
Verifies if the uploaded files are saved in .stl format.
When Rejected:
Please double-check if the files are saved in the stl format.
FILE SIZE
Currently each file uploaded must have less than 50MB, Choose STL binary allowing you to upload more detailed mesh geometries.
When Rejected:
You should reduce the amount of faces in your meshes. You can achieve this by reducing subdivision steps, applying decimation or similar methods. Always check the size of the STL file that you intend to submit.
OBJECT COUNT (LAST & SHOE)
The Object Count check will verify if Shoe and Last STLs contain a single mesh object.
When Rejected:
Please check if the mesh geometry can be split in separate objects before exporting as STL. Common issues, you have separate parts of the whole, you should join these meshes to a single mesh or you have floating objects, you should select only the shoe or last mesh object to be exported.
OBJECT COUNT TIP:
In Blender edit mode, select your object and go to menu:
“Mesh > Separate > by loose parts” may reveal your object is not a single object.
