1 ================================== HEADS Site Release 14.1, User s Guide for Tutorial Data Tutorial 02 Drawing to Data to DTM to Contours ================================== USER's Guide for Total Station Survey Data available as 3D AutoCAD drawing from real life design project. Total Station Survey data in AutoCAD drawing format exists in the Folder Tutorial 02 Drawing to Data to DTM to Contours\Survey Drawing\ SURVEY.DWG. The drawing must be in 3D and should not contain Blocks, In Process1 we shall make Text data file SURVEY.TXT, next we shall Export file GROUND.GEN containing various strings as obtained from Layer names. In Process2 We shall create Survey data file GROUND.GEN, then model files MODEL.FIL & MODEL.LST containing various strings as obtained from Layer names, then Ground Modeling by Triangulation and Finally Contours. Process 1: The folder Survey Drawing inside it, Total Station Survey data in AutoCAD drawing format. Using Heads Site Menu Option File>>Open, Select All Files, Select the file SURVEY.DWG, Click on Open, 1

2 If the file is opened in AutoCAD then close AutoCAD, If the Heads Viewer is not opened then Select menu option Viewing>>Interactive Drawing, As the Heads Viewer opens, use menu option File>>Open, Select file SURVEY.DWG from the above mentioned folder, 2

11 Select Heads Viewer menu option File>>New, this opens a new screen, Select Heads Viewer menu option File>>Draw String, this opens a new screen, 11

12 The Draw String Dialog box appears as shown below, the model name GROUND is currently selected, Click on button Select All to select all the string labels, The Strings LOTS, HOUSE, ROAD & DRAIN under model GROUND are drawn on the screen, this confirms that the model is alright, 12

13 Using Heads Site Menu Option File>>Open, Select All Files, Select the file MODEL.FIL, Click on Open, Select Heads Site menu option Utilities>>Export as GENIO File, 13

14 As the Dialog box comes for Export as GENIO File, the Standard Model String option is already selected, the model GROUND the strings related strings LOTS, P0, HOUSE, ROAD & DRAIN are all listed, Click on button Select All to select all the strings, Click on OK, The process starts, Click on button Proceed, as the process is over click on button OK & Finish, 14

15 The GNIO file is created as NEWFILE.GEN in the working folder, The file NEWFILE.GEN may be opened in Notepad to view the contents, 15

16 The file MODEL.FIL is currently selected in Heads Site, Select Heads Site main screen menu option DGM>>Ground Modeling [Triangulation], The various Survey Features which are stored as string labels in the model files are already selected, Click on button OK, 16

17 As the process starts Click on buttons Proceed, when the process finishes click on buttons OK, the output is written in files HDS000.FIL, HDS001.FIL & Contour.FIL the DTM files will be used in various future process for design to get the ground elevations, Select Heads Site main screen menu option DGM>>Contour Modeling, The various Survey Points in 3D will be taken from DTM files, the interval of elevations for primary contours C001 is mentioned as 1.0m, the interval of elevations for secondary contours C005 is mentioned as 5.0m, (always five times of interval of primary contours) and Elevation values as Text string ELEV at an interval of 5.0m. If the ground is relatively flatter then contour elevations may be given as 0.1m, 0.5m and 0.5m in Contour Data in file Project Data.txt, Click on button RUN, 17

18 As the process is over click on button Save, the Contour are saved under Model Name CONTOUR and String Labels C001, C005 & ELEV in model files MODEL.FIL & MODEL.LST, Maximize the icon for Contour RUN/QUIT from the bottom of the screen as shown below, Click on button QUIT to close the Contour window, 18
