level curve creation

[morwenna]

Good morning to all, I am sorry to put this argument back and I hope that no one will want it but I am in the dismissal zone because I can not extrapolate level curves from a relief made by a cloud of points in 3d. please .. help. the programs I possess are autocad 2007.,3d maz ,autocad map 3 2010. Thank you.

use sitopolo, much more practical for this:
http://www.sitetopo.com/read this discussion in which he talked about it:
http://www.cad3d.it/forum1/showthread.php?t=11876
http://www.cad3d.it/forum1/showpost.php?p=25166&postcount=55then import the curves in autocad (or map 3d).
However always do a little research before.

.... centuries ago I made a lisp (curve.lsp) that served precisely for the purpose:
by clicking on the 3 points placed at various odds, track the lines. Of course, it is necessary to repeat the operation for all "triangoli".
attention that points must have a whole and positive share, therefore not 3.18 or -3.15 but 318 or 315. to the purpose it is necessary to scale the drawing and bring the lowest price to 0.00
when all the design is completed, you can (using faplinea.lsp) turn all polyline lines (fapline allows you to do so by selecting all lines together unlike the standard autocad command that only does 1 at a time).
I hope I was useful!

Hi, I would like to ask you the procedure to follow for the creation of level curves starting from points listed on a dwg file.
so far following the advices reported in other posts, I downloaded and used respectively in the order the lisp to create the dtm and then xls2curves.
perhaps explanations were not exhaustive enough for me, but I couldn't get the desired level curves.
Can anyone give me any further suggestions? thanks (ps: the points listed are relatively few, since the area in question aimed at a river expansion case is a few hectares) thanks again in advance

if you have dtm you can use autowhores of gp. and subsequently autosez-2 to have the sections.
or the freeware program quikgrid, although a little dated.

Hi guys, I'm a new user, I wanted to ask you if it was possible to create a cartography 1:1000 having isoipse in shp format of a ctr at 10000.

 

[heryx]

I have created a shp of the ctr before 10000, then with autocad map 3d I created a dem.
I read that with civilization 3d you can create, but I did not understand well how.
I would need to create a 1:1000 cartography to insert a relief made with a gps trimble, but I did not take many odds so that I could create level curves.

I trust in you genes of cad. :frown:

If you have created the dem with autocad map 3d you need more

Thank you very much for having responded. I had already tried this procedure and failed, can it be because I had set the 3d view?
