Need width of the furniture I am drawing to be 15mm and 18 mm but gets rounded to 0.01mts or 0.02mts

Any way around this? really need to measure/draw things with precision, but everything is rounded up to the smalles size (1 cm or 10mm). Thx in advance!

Change the units and precision to be suitable for your project. Window>Model Info>Units. You may also find it useful to turn off Length Snapping if it is turned on.

let me check that out, thx!
