I am looking for a routine to sort contour lines. I am using 3d polylines that I import from Global Mapper. My problem is all of the lines are on one layer. Ideally, I would like to pick a starting elevation (polyline) and have the routine select every 5th contour up and down. Once then are all selected, I can move them to a new layer (like TOPO-INDEX). Some of these sites are hundreds of acres and have significant elevation changes. To do this by hand is VERY time-consuming (and easy to miss some contours). I am not a programmer, but this seems like the type of task that is ideal for a lisp routine. Any help is appreciated.

I have a great request. I need to scale some polyline contours from ground to grid coordinates. Using the scale comand this works, but the Z value is scaled as well. The thing is, I want to scale the X and Y only, not the Z. So far the only way to do this is to create a block, scale it, then explode. This takes a lot of time that to me seems unnecessary. So this is what I was thinking for a lisp routine that can do what I need. Select a polyline (contours) Scale the polyine to some factor. Reset the Z value to the orginal value before scaling. I hope this makes sense. Haha. Anyone willing to tackle this?

I've never had this issue before and it's beginning to drive me bonkers! I have a combined surface that I've created from an existing topo file and a couple of new survey files. But I cannot label my new surface. When trying to add a single (or multiple) contour label, the drawing will not allow me to select the surface or a contour line. I can click my cursor all over the place and it will not select the surface, and I have to hit Escape to exit the command. Once I am out of the command, the surface is easily selectable, but for some reason it will not let me label it. How do I label this surface?

Hi First time poster here. I've only got AutoCAD13 and there's almost no chance for us to get civil 3d. But I have a 4km pipeline i'm trying to model so I'll need a longsection. Besides doing it manually is there a more efficient method, given the contour file I have is at 0.5m intervals. I'm thinking even a script in Excel that pulls the intersect for the pipeline polyline and contour lines and return the x-y-z coordinates. Thanks

Label Contours That Are XREF In
MillerMG posted a topic in AutoCAD 2D Drafting, Object Properties & Interface
Hey Everyone, Hope everyone is doing well. I was leery on posting this but I feel like the whole point of this forum is to share knowledge so hopefully I can be more efficent at my job. So, lets get started. I have to label contours that are in model space. I know that Civil 3D allows you to label contours that are in a surface but is there a way to label just regular polylines that are an XREF? The way that I currently do it is run the POLYLINE command snap to the contour, look at the properties to get the elevation, edit my text to the appropriate elevation, run my much appreciated LEE MAC LISP of Align Text to Curve and then I'm done. Done with ONE! Is there a way to expedite this without creating a surface? As always, any and all comments/questions are always appreciated. Regards, Miller -
I have a couple of viewports where I just want to show spot elevations of my surface and not the contours. Whenever I freeze the contours my spot elevations disappear too. When I select a spot elevation it's layer shows as "C-TOPO-TEXT" and when I right-click and go to "Edit Label Style" the label layer is "GRADE-P-T". When I select my contour lines they are on a "C-TOPO" layer, and then when I go to "Edit Surface Style", "Display" tab it shows that the major and minor contours are on "CONTMJR-P-L" and "CONTMNR-P-L" layers respectively. My point being that it seems like they are all on different layers, so I would think I could freeze/thaw the two interchangeably. What am I missing? Thanks ahead of time!

Well i have a homework for the university , im working in AutoCAD 2006 , so the project is that, i have a pdf with contours of an area, i have to rasterize it as a jpg picture, pass it to AutoCAD (i have done this so far..) and then i have to find the X , Y and Z coordinates of some points in the picture. Well with the "ID" command, i found the X and Y coordinates but as Z it gives me 0,0000.. How can i pick a point in the jpg and find the Z? I have to find the altitude! (Does i have to make something called georeference?) help!!!! Please guys help!!! ((( -
Hello, well i have a problem on solving an autoCAD homework . i have a pdf with the contours of the altitude of an area and i have to rasterize it as an image in AutoCAD 2006 (i put it on windows paint , then i save it as an img (jpg) ) and then i inserted it in AutoCAD. I have to georeference that image and to fix its scale. How can i do that ? Drawing2.dwg

Hi everyone!!! I know my question should be a easy question for a mid level civil 3d user, but not for me. I need to create a worst defined contour from a surface created via well shaped contours, why I need this, because a need to export a surface without to much detail to a fem program (plaxis). So the question is; How to create new contours from a already created surface_ Hope you can help me.

Hi all, I am new to this site and I am an land surveyor using AutoCAD 2012. Just new to 2012 version, previously used 2005 version. My question is: Is it possible to (and how do I) create a 3D model of a ground surface from field survey data which has been collected. The data i have is currently in Leica GSI format, and has x, y and z coordinates. I can easily transfer this into a .csv file i necessary. Anyone any ideas? Much appreciated guys!

How to import .txt file with .dwg site plan to generate contours
littlerach posted a topic in AutoCAD General
Hi All, As a preface... I'm new here. Now here is my question: a civil engineer sent us a .dwg file for a site survey. However, the .dwg contours are just showing up as a series of overlapping rectangles. He attached two .txt files, one for elevation point locations, the other for tree locations. Both give coordinates... i.e. :452,2718.7202,2509.7896,569.4979,GL etc. I know that the .txt file is giving locations, but I do not know how to generate plines etc. from the given coordinates in the .txt file. I downloaded ascponit.lsp, but i'm not sure if this is meant for this... I'm using AutoCAD 2008. Any recommendations? Thanks, LR
