Thanks to the live preview of objects, their dimension is already visible during drawing.
Since the latest OCAD Update 2020.5.12, the live preview is no more only limited to line objects, but is also available for point objects.
In addition, a so-called legibility halo can be displayed for point objects. The distance of this legibility halo is based on the IOF specifications for orienteering maps and supports the cartographer to draw objects with enough distance to each other.
More information can be found in our OCAD Wiki.
