Looks to me your on the right track. Draw another construction line from A-B and extend it past the ends. Then Draw a circle starting at point B to the number 12 position. Trim this circle to the A-B line. Next draw another line from the A-B line and the B-12 circle, down until it intersects with the top line of the side view. label that intersection 12. Next draw a line from point 12 to the B of the A-B line at the bottom. This will be the true length of that line. This is just a standard projection of lines to obtain the true lengths. Hope that helps, I have to step away for a few Hrs. Good luck.

Ok, I do understand what you are looking for now. There are times when PF is not to clear on the instructions. I did my drawings in 2009 so many updates may have happened since then. This clip pretty much shows what PF is talking about in the instructions. I did not check each point against your instructions, sorry. But had to leave you with a reasonable understanding of the procedure. When you go through the instructions, just do one thing at a time. You will get there.

Let me know if this is what you are looking for. (defun c:cc ( / sset blk newscl) (if (setq sset (ssget "_x" (list '(0 . "INSERT") (cons 410 (getvar "ctab"))))) (progn (setq blk (ssname sset 0)) (entmod ; modifies the properties of the entity (append ; combines the list (entget blk); indicates what entity to edit (list ; create a list of properties to change (cons 41 1.025) (cons 42 1.025) ) ) ) (entupd blk); updates the block (command "_.explode" blk "") ) (prompt "\nNo blocks in drawing!") ) (princ) )
