, We used a little geometry type, line, surface, body (bodies, in cases involving the use of three-dimensional) in ArcGIS, but in addition to that may be encountered with the type of ZM, as shown, surface ZM it is similar to the surface, but more than two multi-surface fields.
In the Edit Sketch Properties view seen Z and M values. Elevation value Z is used to store attribute information m, M value is used to store additional attribute information, such as temperature, concentration and the like. Here the data is transferred from the CAD file, all have elevation values, but no M values.
WKT format from the following points may be seen that the geometry of the types Point, PointZ, PointM, PointZM four formats, Polyline, Polygon also similar.
AutoCAD derived from the topographic data, because most of the information contained Z, so the lead into Shape, which is the type with ZM, sometimes, for example the MapGIS, it does not recognize the type of geometry of the belt ZM Shapefile file, I guess he's a programmer by value of the field to direct determination. So how do we remove geometry type ZM with it?
Geographical process - environment, M and Z values set parameters to Disabled. (You can also set the ArcGIS tool, that will only take effect the current tool)
