We are using LDC. We are trying to set it up for the linework, and are having some difficulties. can someone tell me what the * and the $ are used for and if there are any other commands or codes like this that I should be aware of. as well I originally started to use "st" at the end of a code to get the line work in, I was told this is wrong that I should be using "B" before the code.

As you can see the office is truly lost, and I have no experience with this at all, any and all information would be helpfull.

Thank you
