These functions are not available in 3DF Zephyr Lite and 3DF Zephyr Free.


By clicking on Tools > Sections and Contour Lines you can select the drawing element you want to create choosing from:


  • Sections: this tool generates only one plane that you can move, rotate and resize; the position of the plane can also be modified using the control points, if they have been previously placed on the 3D model;


With this tool, a window will pop up after the plane has been placed (see image below).



In this window you can draw sections and contour lines previously identified by the planes both automatically or manually. In the upper bar of the window there are editing and drawing icons as follows (from left to right):


 - Create: manual method that allows you to draw a polyline;

 - Remove: removes the vertex of a polyline;

 - Move: moves the vertex of a polyline;

 - Split: adds vertex to a polyline;

 - Clear: deletes all polylines;

 - Close Polylines: closes a polyline;

 - Smooth Polylines: allows you to smooth all the polylines drawn;

 - Autocompute Current: generates a polyline only on the section shown in the window;

 - Autocompute All: generates a polyline for each section previously created using the planes;

 - Export: allows export of drawings as .dxf and .shp format;

 - Import to Workspace: allows to import drawing elements in Zephyr workspace;


Previous and Next icon allow scrolling among the sections created.


  • Track Sections: this tool generates several planes (user can fix the amount of those) on each position of the control points so it is worthwhile when it is necessary to draw sections on an irregular path (for example, a river bed);


  • Contour Lines: allows generation of one or more contour lines on the 3D model and user can choose the reference axis for contour lines direction;


  • Elevation profile from Drawing Element: allows generating elevation profiles if at least one drawing element (polyline) has been created. Please check the DEM Viewer section to understand how the elevation profile tool works.
