    repeat a selection on last group of entities?

    Hi, I am sorry. I said the selection set is set whenever you undo. I meant the selection set is released whenever you undo, but you use may also save the set as an autolisp variable: (setq a (ssget)) and then use it for other acad commands, for example: Command: list Select objects: !a...

    repeat a selection on last group of entities?

    Hi, Jasonx10: Back from previous autocad versions, you could use SELECT command to make a selection set, and from then on, used them as previous. The selection set is set whenever you undo, back you can always use SELECT. Hope this helps, Roberttx

    Computing depths of sewer line - acad- excel

    Hi, pmover: I just reviewed the problem with another guy; he came up with a solution. I had to compare vertical depths of sewer line and classify them in ranges (0 to 6 feet, 6 to 8 feet, 8 to 10 feet, etc) in order to pay for excavation items. However, what we did is export an ascii file for...

    Superelevation

    Hi, longisland: You might find examples of these curves on Mannering's book: Principles of Highway Engineering and Traffic Analysis. Also, you need a certain distance between curves in order to perform the change of superelevation in the curve to the tangent. The maximum percent inside of...

    Input data from .txt file

    Hi, cad123: I read it. I am not into dialog boxes. I am sorry. Good luck. Anyway, using Bayou's suggestion, you can still modify the profile using custom made lisp apps, like labeling slope, endpoints, lengths, etc. For instance, I am sending you a slope program I made. Robertx. (defun c:sc5...
