What SHP Schemas Support

A SHP schema can support the following:

■ A single geometry type per file

■ Spatial contexts (determined by coordinate system information in the PRJ

file)

■ Auto ID generation

■ Null value constraints

■ The following geometry types:

■ Polygons: polygon, multi-polygon

NOTE When you connect to or import SHP polygon data, AutoCAD Map

3D checks the geometry to see if there are multiple closed outer loops. If

so, it treats the geometry as multi-polygon (a polygon with multiple exterior

rings). It does not treat unclosed outer loops as multi-polygon. You can

create a multi-polygon in AutoCAD Map 3D and then save or export it to

SHP format. It then appears in its native SHP file as a multi-polygon.

■ Points: point, multi-point

■ Rings: linear ring

■ Line strings: line string, line string segment, multi-line string
