For this reason, QCAD does not show the unit everywhere but only in the drawing preferences. Also all values displayed by QCAD can be considered to be in that same unit. Once you switch your drawing unit to millimeter (or any other unit), all distance values you input including coordinates are considered to be in that unit. Further, some dimension label formatting options are only available for drawings in imperial units (inch, feet). Another situation in which the drawing unit is used is when scaling a part library item that was created in a different unit into a drawing.

The drawing unit might also be indicated in a drawing header or similar.įor QCAD, the drawing unit is significant mainly for printing a drawing on paper at an exact scale. As a CAD user you are expected to be aware of the unit in which your drawing has been constructed. This means that the unit of a line with a length of 10 is irrelevant to the CAD system. Note that all CAD systems (including QCAD) generally operate unit-less.
