This example in the movie comes from the USA where the unit of measure is decimal feet. T he principles are the same when working in the metric environment.
Landscape plans are drawn full size in gCADPlus software. It is possible to apply dimensions to entities in the drawing taking the dimension value directly from the CAD model. This is a difficult concept for designers who are new to CAD drafting. We let the software do the hard work, not the other way around.
In the movie, entity snaps are used to precisely position a linear dimension. Once placed, the appearance of the dimension is improved by by fine tuning the dimension style by reducing text height and moving text closer to the dimension line. If it is necessary to adjust the position of lines, we show that the ORTHO switch allows for that without altering the dimension value.
