3DReshaper includes also a complete toolbox to create and manipulate polylines.
Compute sections very easily in order to get for example contour lines on your DTM. Sections can be computed in every direction, around an axis or along a given curve.
A lot of features dedicated to polylines
Many tools are available to further improve polylines once created. They can be:
Massive and Automatic Breaking Lines extraction on a Mesh
Computing Break Lines is a very common job in Surveying, that is the reason why 3DReshaper brings you an automatic solution to extract them massively from a 3D mesh. In the Surveying plugin, the command "Extract Breaking Lines" allows you to find all the breaking lines from a mesh. Thanks to this function, you will have for example all the crest and ravine lines on your Digital Terrain Model. Some tools are embedded in the command to improve manually extracted lines if necessary.
