NAME

LOCK - Set the default lock angle for a given device  

SYNOPSIS

LOCK <angle>  

DESCRIPTION

Set the lock angle, in degrees, for constraining line segments. The default angle is 0.0 which turns off all constraints. Invoking LOCK without any arguments prints out the current <angle> setting.

When extending a line using the mouse, the mouse coordinate is modified such that the angle of each new segment is snapped to the closest multiple of the LOCK angle, consistent with the current drawing grid. In practice, this produces precise angles for 45 and 90 degrees, but may result in slight angle errors for other settings, especially on coarse grids.

This command sets a variable stored with the current device. The lock angle is stored in the device definition file, so is persistent across edits.  

OPTIONS

<angle>
The lock angle in degrees between 0 and 90. If a floating point number is given, the resolution will be rounded to the nearest 0.01 degrees.
