Start of persistent reactors group; always “{ACAD_REACTORS” |
330 |
Soft-pointer ID/handle to owner dictionary (SPATIAL) |
102 |
End of persistent reactors group, always “}” |

Number of points on the clip boundary 2 = Rectangular clip boundary (lower-left and upper-right) 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) |
