TXT exports each contour line as a series of X, Y, Z points. The Z coordinate for each vertex is also stored in the associated. SHP exports a shape polyline Z type where each vertex along the line comprises an X, Y, and Z coordinate. The Z coordinate for each vertex is stored in the associated. SHP exports a shape 2D polyline type where each vertex along the line comprises an X and Y coordinate. Use the File | Export command with the Write LWPOLYLINE entities even when 3D data is available export option checked to export the contours as LWPOLYLINE entities with the Z values as an attribute for each line. Use the File | Export command with the Write LWPOLYLINE entities even when 3D data is available export option cleared to export the contours as POLYLINE entities with the Z values written for each vertex. DXF file are saved with 64-bit floating-point precision. The contours are not affected by 2D page transformations or rotations. Axes, labels, contour fills, line properties (width, style, and color), etc. The polylines are clipped to the map limits and scaled to the current map scale. The POLYLINE entities in the DXF have X and Y coordinates for each vertex, and the Z coordinate is stored as an attribute for the lines. The contours are saved as elevated polylines. The following file types are available for export when using the Export Contours command. The Export Contours command automatically removes the contour labels from the output and closes the gaps where the labels were, and the Export Contours command only exports the contours lines, regardless of which items are visible in the map. However, the Export command will also export any other visible items in the map, including contour labels. The Export command can also export 2D or 3D BLN, DXF, SHP, or XYZ Points files. The File | Export command can be used to export Z information to an attribute field for BLN, BNA, DXF, GSB, GSI, KML, KMZ, MIF, and SHP files. GSR2 is required to define the coordinate system. The grid has the same coordinate system as the original data file, but the. It is recommended to check the GS Reference (Version 2) file if you intend to use the grid file in Surfer, as the GSR2 retains all of the information needed. The Export Options dialog appears with the option to save the coordinate system information. Surfer prompts to save the coordinate system and projection information, if one is specified for the map. The Export Contours command exports the currently selected contour map as an AutoCAD. QCAD now enters the list of coordinates just as if you would have entered them one by one manually, and in the process draws points, lines, a polyline, spline, circles, text labels or whatever the tool creates.To retain the Z information for contour lines for use in other mapping programs, click the Map Tools | Layer Tools | Export Contours command or the button. Paste the list of coordinates into the command line input field using Ctrl-V (or ⌘V on macOS).
This can for example be Draw > Line > Line from 2 Points, Draw > Polyline > Draw Polyline, Draw > Circle > Center, Radius or any other tool that accepts a sequence of coordinates as input.Ĭlick into the command line input field or press the space bar to make sure the command line has the keyboard focus. Step 1: Getting the Coordinates into the Right Formatįirst, get the coordinates into the following format (for example through a CSV export from a spreadsheet): x1,y1Ĭopy the whole list of these coordinates to the clipboard (select the multiple lines from the plain text or CSV file and copy to clipboard in a text editor).
Based on these coordinates, QCAD can create points, lines, a polyline, a spline, circles with a given radius, text labels at the given coordinates, etc. QCAD offers a simple and convenient way to quickly import or use a list of plain coordinates. These coordinates may for example originate from a spreadsheet, CSV file or a 3rd party program.
