Exact sizing of holes

working in metric, when I set and lock the size of a square hole, 7.88 and 11.88 Easel changes the eize by rounding out. how can I change this habit?

Have had that problem several times especially when there are groups of pockets, the position may change as well as the size may drift.

simply put: use a software that is intended for mechanical design, such as Fusion360 or Solidworks.
Easel was not intended for strict position/sizing and rounding occurs throughout the software, this rounding simplifies the toolpath calculation process later on, which allow it to run within a browser and use less processing power/ram than those other softwares… GL
