Translations:Sketcher Tutorial/65/en

In the first part it was shown that construction geometry is not necessary for constructing triangles. But nevertheless the sketcher provides construction geometry, which is useful for more complex problems. Any line can be converted to a construction line with the button. The construction lines are shown in the sketch as blue lines. They can be used for constraints in the same way as other lines, but are not shown and not used when the sketch is closed.
