Tools for plane and line locking are implemented. Most of the locking sub-functions require that the current point is set. If not so, it can be set using the SET CURRENT sub-function prior to the lock command.
Note: These commands are ignored if the system has set an initial STATIC lock. (plane lock).
Implies that the point to be defined will be projected on the plane. The resulting point will then be the point on the locking plane closest to the given point (intersection between the locking plane and a line through the given point and perpendicular to the locking plane).
-
LOCK VIEW: A plane through the current point. The desired plane (projection) is identified by the user.
-
LOCK EVENT PLANE: A plane through an event point and perpendicular to the event vector. The desired event point is identified by the user.
-
LOCKX, LOCKY, LOCKZ: The current value of X, Y, Z respectively is locked. The locked plane will be highlighted in all views by showing the normal vector of the plane starting at a point in the plane (line lock). Implies that the point to be defined will be projected on the line. The resulting point will then be the point on the locking line closest to the given point (intersection between the locking line and a plane through the given point and perpendicular to the locking line)
-
LOCK U: A line through the current point and parallel to the v-vector in a plane. The desired plane is identified by the user.
LOCK V:
As LOCK U but parallel to the u-vector.
LOCK YZ:
A line through the current point and parallel to the X-cardinal vector (1,0,0).
LOCK XZ:
A line through the current point and parallel to the Y-cardinal vector (0,1,0).
LOCK XY:
A line through the current point and parallel to the Z-cardinal vector (0,0,1).
LOCK EVENT LINE:
A line through an event point and parallel to the event vector. The desired event point is identified by the user.
LOCK ANY LINE:
A line passing through the current point and a second point. The second point is defined by the user (supported by the 3D point concept). This lock tool in combination with OFFSET FROM CURRENT enables the "hidden" sub-function DISTANCE ALONG. The locked line will be highlighted in all views.
UNLOCK:
This command cancels a previous lock, if any.
