Created by: Durman

The expected nodes:

Intersection edges mode 2D:

example

• code
• docs
• tests

Make monotone polygon 2D:

example

• code
• docs
• tests

Edges to face 2D:

example

• code
• docs
• tests

Try to use code of the node for bisect node. Planar edgenet to polygons node probably should be removed - for discussion

Merge mesh 2D light:

example

• code
• docs
• tests

Crop mesh 2D

example

• code
• docs

Dissolve faces 2D:

Inset faces 2D: look

finally:

• #2657 (closed) number of overlapping
• project an intersection point
