# fracture intersections scanline command

Syntax

- fracture intersections scanline keyword <range> (3D only)
Primary keywords:

Create intersections corresponding to scanline mapping. Scanline mapping occurs on a planar surface that is specified with the surface keyword. The measurement surface must be a planar, convex polygon. All fracture intersections with this surface that also intersect one of a set of the specified scanlines (see the scanlines keyword) are added to the specified intersection set.

- intersection-set s
Set the name of the resulting intersection set containing the scanline traces. The specified intersection set must not already exist.

Usage Example

The following example illustrates how the `fracture intersections scanline`

command can be
used to compute the scanline on the plane named “plane” along the line named “line” and save the
mapped traces in an intersection set.

```
model new
model random 10000
model domain extent -5 5 -5 5 -5 5
;Generate fractures using the default template
fracture generate fracture-count 1000
;Define the scanline plane
geometry set 'plane'
geometry polygon create by-positions (-4,-4,0) (-4,4,0) (4,4,0) (4,-4,0)
geometry set 'line'
geometry edge create by-position (-4,0,0) (4,0,0)
;Calculate scanline traces (e.g., fracture intersections with the plane)
fracture intersections scanline intersection-set 'scan' lines 'line' surface 'plane'
return
```
