Import LandXML Surface and Breaklines (option) addon for Blender 3.0

Import LandXML Surface and Breaklines (option) addon for Blender 3.0

(Works from Blender 2.8)

This addon is to import Surfaces and breaklines (option) from a LandXML, exported from for example Autodesk Civil 3D.
The Surface name is the 'Surface name' in the LandXML-file.
For each Surface in the LandXML-file there wil be a new material with a random color. This material wil have the same name as the Surface. After importing the Surface(s) you'll need to cleanup the mesh(es) (delete duplicate vertes) this can be done in edit mode: Mesh > Clean Up > Merge by Distance
or [F3] Type: Merge by Distance.
While importing the breaklines and Surfaces, the collection name is the 'Project name' in the LandXML-file. While selecting the LandXML-file, there are two options:

  • Import Breaklines
  • Close lines

Option: Import Breaklines:

To import the Breaklines as well, select this option.
For each breakline in the LandXML-file there wil be a new mesh
Select the lines (read meshes), hit [CTRL+J] and it wil be one mesh.

Each imported breakline will be imported as a seperate mesh but it will be in the same collection.

Option: Close lines

Sometimes it is needed to close the breaklines, to do so select this option. You can also do it by hand...

Each imported breakline will be imported as a seperate mesh but it will be in the same collection.
While importing the breaklines and Surfaces, the collection name is the 'Project name' in the LandXML-file.
