The levels are used to classify the points according to their type, so that we can choose their membership in the digital model, as well as their visibility. By default there are levels 0 (Default), 1 (Fill), 2 (Break), 3 (Information) and 4 (Stakeout).

In the code database, the equivalence of each point code with its level is specified, and when importing points, the Classify points by levels box can be activated to assign them automatically.
