Hi,
I am designing a rural street and am having problems giving proper exit to water. What would you recommend for "absoulte minimum" slope for v-ditch dirt swale. The swale measures 12' wide, 8% each side.
Thanks,

Hi, Vic31,
You may want to start either with CNA or INEGI, both entities in Mexico. I am not sure if they have this particular info, but I might start there.

Hi,
Does anybody know the starting salary for a recent pe civil working in highway, roads and streets design, in texas (el paso) or similar areas? I also have 8+ yrs design experience, pre-PE.
Thanks,

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...
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,

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...
Hi,
I have to make a calculation of several sewer lines depth against ground line indicating the depth in ranges (0-6 feet, 6-8, 8-10 etc.) The file is in autocad. Does anybody have an idea about how can I accomplish this through excel?
Thanks a lot,
Roberttx.
Hi, borgunit:
These lines are not parell, are somehow horizontal. I have to calculate the difference in vertical profile for ground elevation and proposed sewer line, but both changes in slope and the calculation is depths of 0-2 feet, 2-4 feet and so on. We used to do it manually for few...
Hi,
I have to calculate the vertical distance between two lines or plines and account for ranges (0-2, 2-4, 4-6, etc). Is there a way to do this in lsp?
Thanks,

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...
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.
