need help in "on plane"

Hi,

what's about the help file? Broken?

hm_createmark entity_type mark_id '?option?' 'list'

'on plane' 'x y z i j k tol plane touching'

Place entities on mark_id if they are within tol of the plane or vector defined by (x, y, z, i, j, k).

x – base x coordinate

y – base y coordinate

z – base z coordinate

i – normal x component

j – normal y component

k – normal z component

tol – tolerance to use to search for entities

If plane is 0, all entities must be within tol of the vector defined by (x, y, z, i, j, k).  Otherwise, all entities must be within tol of the plane defined by (x, y, z, i, j, k).

If touching is 0, all points of the entity must touch the vector or plane.  Otherwise, at least one point must touch the vector or plane.  For solids, if touching is 0, no solids will be found.

Regards,

Mario
