Common Group Codes for Objects. For information about abbreviations and formatting used in this table, see Formatting Conventions in This Reference.
The following group codes are used by SPATIAL_FILTER objects. In addition to the group codes described here, seeSPATIAL_FILTER group codes 


Group code 
Description 
0 
Object name (SPATIAL_FILTER) 
5 
Handle 
102 
Start of persistent reactors group; always â€œ{ACAD_REACTORSâ€ 
330 
Softpointer ID/handle to owner dictionary (SPATIAL) 
102 
End of persistent reactors group, always â€œ}â€ 
100 
Subclass marker (AcDbFilter) 
100 
Subclass marker (AcDbSpatialFilter) 
70 
Number of points on the clip boundary 2 = Rectangular clip boundary (lowerleft and upperright) greater than 2 = Polyline clip boundary 
10 
Clip boundary definition point (in OCS) (always 2 or more) based on an xref scale of 1 DXF: X value; APP: 2D point 
20 
DXF: Y value of boundary definition point (always 2 or more) 
210 
Normal to the plane containing the clip boundary DXF: X value; APP: 3D vector 
220, 230 
DXF: Y and Z values of extrusion direction 
11 
Origin used to define the local coordinate system of the clip boundary DXF: X value; APP: 3D point 
21, 31 
Origin used to define the local coordinate system of the clip boundary DXF: Y and Z values 
71 
Clip boundary display enabled flag 0 = Disabled; 1 = Enabled 
72 
Front clipping plane flag; 0 = No; 1 =Yes 
40 
Front clipping plane distance (if code 72 =1) 
73 
Back clipping plane flag; 0 = No; 1 = Yes 
41 
Back clipping plane distance (if code 73 =1) 
40 
4x3 transformation matrix written out in column major order. This matrix is the inverse of the original block reference (insert entity) transformation. The original block reference transformation is the one that is applied to all entities in the block when the block reference is regenerated (always 12 entries) 
40 
4x3 transformation matrix written out in column major order. This matrix transforms points into the coordinate system of the clip boundary (12 entries)
