Using a specified minimum wire width

Hi everyone,

Is there any way to make Nanoroute use a minimum wire width? for example using of 0.15 instead of 0.1 um in MX. I tried NON DEFAULT RULE with the provided lef file from the foundry,  however seems it is not affecting all wires and even in one wire it just changes some segment's width based on space and room  availability and DRC violation. 

Best Regards,
