# Correction tools: global correction

## Global correction

The global correction tools permit to accurately render automatically according to the whole geometry on which there are potential faults. Several tools are available :

- Heal all intersections
- Heal all superimpositions
- Simplify all lines
- Heal and simplify all geometry

## Heal all intersections

The correction tool « Heal all intersections » permits to correct automatically all the intersections detected on the assembly of the geometry. On each intersection a fragmenting is made.

## Heal all superim-positions

The correction tool « Heal all superimpositions » permits to correct automatically all the superimpositions of the lines detected on the assembly of the geometry. On each superposition, a merge is made so as to create a single line on the common sections.

## Simplify all lines

The correction tool « Simplify all lines » permits to simplify automatically all the configurations of two adjacent lines, collinear and not superimposed on the assembly of the geometry in a single line.

## Heal and simplify all geometry

The correction tool « Heal and simplify all geometry » permits to carry out together global corrections in one action, namely: correct all the intersections, all the superimpositions and simplify all the lines of the geometry.
