This page describes the general operations and principles of Constructions.
More information about all features of the Construction Tools Sidebar, see : 2D Constructions.
Construction tools are used to help you calculate and position exact locations. Look at them as your ruler and measure equipment to set out new coordinates.
There are 2 types of construction tools : Points and Lines. A Construction Point has a single location. You can create as many as you need. A Construction Line as a position and orientation but has no length. You can create as many as you need.
Constructions are georeferenced and can be saved in a special file (*.ocf) so you can use them again or forward them to a college.
Construction tools are mostly used to edit objects.
While editing objects, the snap function will use constructions as anchorpoints.
