Warning: Model too small to load

Recommended Posts

Posted · Warning: Model too small to load

I have constructed a model in 123 D design and obtain the message above (from CURA) when attempting to load into CURA

I am using Ultimaker 2+

The model can be contained in a block about 20mm x 40mm x 30mm (x,y,z) and has a minimum wall thickness of 1mm

although generally 2mm.


I have been unable to find any references to minimum size from on-line manuals etc. so am now trying here for help.


Any advice much appreciated.

STL files don't store the units.  Even if you designed it in mm in 123D, you may be exporting it in inches or meters or feet.  For example if it's in meters and because cura expects mm it will be 1000X too small.


So when you export from 123D I think there should be somewhere an option to select the units.  Select mm.

Many thanks for your quick response. Although your answer did not help directly, it put me onto the solution. 

Whilst looking for the option to 'select mm' (not available) I came across the option to 'Combine objects'.(please see attached)

Happily this solved the problem immediately and Cura accepted my model.
