Q:

How can I delete all added weights? The DELETE ALL WEIGHTS command does not touch the ones with "+" in front of the first word. For example,

ADD "+Light ship adjustment" 12.34 50.67 0 6.54
DELETE ALL WEIGHTS

doesn't get rid of "+Light ship adjustment".

A:

As it states in the manual, DELETE ALL WEIGHTS causes all added weight items to be deleted, except those beginning with "+" or "*+".

In other words, your added weights like those in the example above are hard to get rid of. You have to either use the DELETE command, naming which items to delete, or use the CLEAR command and reread the geometry.

However, with a little planning there is another way. Note that the command

DELETE xyz

will delete all added weights that begin with the "word" xyz. For example, it will delete "xyz abc" but not "xyxabc". You can take advantage of this by making sure there is a space after the leading "+" in your lightship added weight items. Then you can say,

DELETE ALL WEIGHTS
DELETE "+"

to delete them all.
