[Qgis-user] create clean knot-edge-model

[Nicolas Cadieux]

Hi,
You have multiple plugins and tools available.  You can download the following plugins:

Geometry Checker
Topology Checker

Look in the main menu or in the processing tool box for the following:

Multipart to Singlepart
Check validity (use both methods)
Remove duplicate vertices
Deleted duplicate geometries 
Snap geometries to layer, (search for snap in processing)
V.clean (break an snap,rmdangles....) see the cleaning tools.

Some of these are unstable like check Geometries.  Try fixing one problem at a time for better stability.
Nicolas
