Group codes<br />
Description<br />
210 Normal to the plane containing the clip boundary<br />
DXF: X value; APP: 3D vector<br />
220, 230 DXF: Y and Z values of extrusion direction<br />
11 Origin used to define the local coordinate system of the clip boundary<br />
DXF: X value; APP: 3D point<br />
21, 31 Origin used to define the local coordinate system of the clip boundary<br />
DXF: Y and Z values<br />
71 Clip boundary display enabled flag<br />
0 = Disabled; 1 = Enabled<br />
72 Front clipping plane flag; 0 = No; 1 = Yes<br />
40 Front clipping plane distance (if code 72 = 1)<br />
73 Back clipping plane flag; 0 = No; 1 = Yes<br />
41 Back clipping plane distance (if code 73 = 1)<br />
40 4x3 transformation matrix written out in column major order. This<br />
matrix is the inverse of the original block reference (insert entity)<br />
transformation. The original block reference transformation is the one<br />
that is applied to all entities in the block when the block reference is<br />
regenerated (always 12 entries)<br />
40 4x3 transformation matrix written out in column major order. This<br />
matrix transforms points into the coordinate system of the clip<br />
boundary (12 entries)<br />
