Only parts smaller than 500 x 500 x 500 millimeters are supported for CNC machining. This might change in the future as we expand the network of our suppliers.
The upper limit for the file size is 128Mb. If your CAD file exceeds this limit, please make sure the export settings are correct. If you are trying to upload a full assembly, split your file into individual parts and upload them separately.
This means we have detected multiple separate geometries in your file. If you are trying to upload a full assembly, split your file into individual parts and upload them separately.
This means that we were not able to detect any geometry in your CAD file. Make sure your file is exported correctly and try to upload it again.
We support most of the common CAD formats for CNC machining. STL and OBJ files are not suitable for CNC machining as they lack the precision required by our suppliers.
This is a often a sign of a corrupted file. Make sure all the surfaces are stitched and your file is exported correctly.
