# Vector Geometries from Repeatables

Assume you have a repeatable field called `vector_vertices` with location enabled, location required, and a minimum count set to 2. Every repeatable record will act as a vector node or vertex and we can use calculation fields to combine all of these vertices into a well-known text (WKT) geometry object field at the parent record level.

Line Geometry:

``````var coords = [];
if (\$vector_vertices) {
for (var i = 0; i < \$vector_vertices.length; ++i) {
coords.push(\$vector_vertices[i].geometry.coordinates[0] + ' ' + \$vector_vertices[i].geometry.coordinates[1]);
}
SETRESULT('LINESTRING (' + coords + ')');
} else {
SETRESULT(null);
}
``````

Polygon Geometry:

``````var coords = [];
if (\$vector_vertices && \$vector_vertices.length > 2) {
for (var i = 0; i < \$vector_vertices.length; ++i) {
coords.push(\$vector_vertices[i].geometry.coordinates[0] + ' ' + \$vector_vertices[i].geometry.coordinates[1]);
}
coords.push(\$vector_vertices[0].geometry.coordinates[0] + ' ' + \$vector_vertices[0].geometry.coordinates[1]);
SETRESULT('POLYGON ((' + coords + '))');
} else {
SETRESULT(null);
}
``````

To view the polygon vector geometries in CARTO, you could use the following SQL query, where `polygon_wkt` is the name of the calculation field and `repeatable_vector_geometries` is the name of the table:

``````SELECT cartodb_id, ST_Transform (ST_GeomFromText(polygon_wkt, 4326), 3857) AS the_geom_webmercator FROM repeatable_vector_geometries
``````

NOTE With the release of the Lines and Polygons feature, you can now set a record's geometry to a `Polygon` or `LineString`, which allows you to view these geometry types from within Fulcrum
