Unfortunately, I don't seem to remember the exact conversion software, and think there must be an . Contours originating from AutoCAD Civil3D will often contain many thousands of vertices per contour. KML file from google earth -> GPS Visualizer (https://www.gpsvisualizer.com/elevation) to add elevations -> copy the lat & long into an excel sheet that converts to northings & eastings (see attached excel sheet named CONVERTER)--> copy northings, eastings & altitude into one new excel sheet (see attached named NEZ) --> set up civil 3D with drawings settings & UTM WG84 (for Sharjah) & 40North setting -> then add surface & point file. Do you have Civil 3D if so then its just a case of choosing a contour label style and contours will appear. Author: David DiBiase, Senior Lecturer, John A.

So I've been trying to import contour lines from civil 3D into watergems and the contour lines dont show up when I zoom extent. Related to this element of subjectivity is the fact that the fidelity of a contour map depends in large part on the distribution of spot elevations on which it is based. How can I make the following table quickly? In general, the density of spot elevations should be greater where terrain elevations vary greatly, and sparser where the terrain varies subtly. I believe I created a PDF file of the contour lines, then used a PDF to DXF conversion software to convert it to a AutoCAD file, and then imported and superimposed those lines onto my drawing.

You can follow this conversation by subscribing to the comment feed for this post. I tried to draw a polyline on civil 3D on the contour lines, when I import as DXF through background layers into watergems, and I turn the bing map on, THE LINE ITS COMPLETLY ELSEWHERE ON SOME RANDOM OCEAN. Jason, Posted by: Set it to Solid if necessary. 5 Ways to Connect Wireless Headphones to TV. You should make separate photos for the different detail classes. By 2. I believe I created a PDF file of the contour lines, then used a PDF to DXF conversion software to convert it to a AutoCAD file, and then imported and superimposed those lines onto my drawing. In order for WaterGEMS to see the DXF file, it needs to contain plain elements like polylines and points. How to retain only the black outlines of colored drawings, and then convert to SVG (vector file), Simplifying paths in Illustrator after coping contours from Matlab, Converting a floorplan image to SVG paths (in Inkscape, or alternative), Cut a combined path along pair of non-connected nodes in Inkscape, Trying to determine if there is a calculation for AC in DND5E that incorporates different material items worn at the same time. It should be noted that the assumption that elevations increase or decrease at a constant rate is not always correct, of course. In this case, for our area, we have the contour lines as polylines in our drawing and we want to use them to create a surface. Keep in mind the following characteristics of contour lines (Rabenhorst and McDermott, 1989): How does your finished map compare with the one I drew below? You should see the surface, with points in red and white contours, since this is the standard style. In the panel we will indicate that what we are importing are items on the ENZ order Easting Northing Zelevation (X, Y, Z), and separated by commas. I think your playing with two different methods at the same time a DTM TIN etc is different to a solid they both have different ways of displaying a similar answer a solid is one object, a surface is an object created from and updated by a number of independant points. Select AutoCAD Files (*.dwg, *.dxf) from the menu to the right of the File Name field (see the image to the left). I can make it a pdf but tried a couple converters and they don't convert the jpg data to vector data. Note: Your post will require moderator approval before it will be visible.

Now draw ticks to mark the points at which elevation contours intersect each triangle side. All files to be zoomed to drawing extents in paper space. In this case, lets add a file of points, before we saw how to do it from an external database. In this way the points are loaded to the file, but not only been admitted as a layer of points but have become a surface operation. Jason E. Lutz | Overview of Analyzing Raster-Based Surfaces, Adding and Modifying Contour A useful characteristic of TINs is that each triangular facet has a single slope degree and direction. ..so please how can i add polylines as contour (converting them to ) ..thanks to all whom help this forum to be always in the first page on google search :), adnhmz you can import 3d lines and make a surface in CIV3d just look under Toolspace Surface for "Definition" "Drawing objects". The result is a triangulated irregular network (TIN). All files are to be thoroughly purged. settings, such as elevation interval and units, you must remove This means AutoCAD (and your converters) are not able to convert the raster to vector information.
