Description
The Loftbook command is used to specify the contents of the offset table and to output the results to a file.
The user defines the number of columns per page (either 80 or 132) and optionally the number of lines. In addition the user can specify that the lines are single spaced, that means, no blank lines are output between rows.
The user defines which pairs of curve types to intersect. Optionally the user can specify for a given curve type, that only those curves from a particular layer or layers are intersected otherwise all curves of a specified type are intersected. The user can define any number of intersection pair types.
After all intersection pairs have been specified the results are output to a specified file.
The user can also clear all current loftbook settings.
