I'm trying to get a custom association list with the format: ((("TAG1" . "VAL1A") ("TAG2" . "VAL2A")("TAG3" . "VAL3A") ...) (("TAG1" . "VAL1B")("TAG5" . "VAL5B) ("TAG7". "VAL7B") ...) (("TAG1" . "VAL1C)("TAG3" . "VAL3C")("TAG4" . "VAL4C") ...)) So far, I can generate this list. So, in essence, the keys of each sublist (tags) in the list can differ slightly, meaning some tags can be missing in the other sub list. Where this happens is when attributes of blocks differ by a bit, with some values missing from another. When we use "ATTOUT", AutoCAD bypasses this by inserting empty values when you read the file as a csv file. When I'm trying to create a CSV file, I'd like to have these tags be at the first row and fill up values per item in the list. What I want is basically an ATTOUT but with my own association list. I'm trying to use Write CSV by Lee-Mac for this. So far, the only way I can do this is brute force the first row with the tags, and then extract each Value such that (("TAG1" "TAG2" "TAG3" "TAG4" ...) ("VAL1A" "VAL2A" "VAL3A" "VAL4A" ...) ("VAL1B" "VAL2B" "VAL3B" "VAL4B" ...)) Any ideas about how I should go forward with these.

Hi everybody. I am new to lisp, so I need your help. I have a diagram with different lines. I need to select each line separately and change a color and a line weight of it. I have one problem right now. here is the example of my selection set line (setq ssLine (ssget "X"(list (cons 0 "LWpolyline")(cons 8 "0")(cons 62 253)))) I want to keep everything the same except the last CONS (cons 62 253). I want it to take a value of a color from a object that I will select in my drawing. First, I need some command or variable to prompt me to select a line. After that, I need my selection set to change the last cons from color 222 to a color of the selected object. Thank you, AB
