Calculate Earth Volumes: Create and Analyze New Surfaces Using Three Methods

This guide details three effective methods to calculate earth volumes by creating new surfaces in terrain modeling software. Users will learn to establish a new surface, input breaklines, and define site geometry. Step-by-step instructions include how to enter data, apply edits, and manage surface names. Whether employing terrain volume calculations, grid volumes, or section volumes, this resource offers comprehensive techniques for accurate volume determination and analysis, essential for landscape design and earthwork projects.

  1. MAKE A SURFACE FROM NEW STRUCTURE CREATE NEW SURFACE CALCULATE EARTH VOLUMES 3 METHODS

  2. Calculate Volume TERRAIN TERRAIN MODEL EXPLORER

  3. RIGHT CLICK ON TERRAIN Calculate Volume (Cont.)

  4. LEFT CLICK ON CREATE A NEW SURFACE Calculate Volume

  5. RIGHT CLICK ON SURFACE 2 LEFT CLICK ON RENAME Calculate Volume

  6. GIVE A NEW SURFACE NAME SURFACE HAS NO DATA YET HIT OK Calculate Volume

  7. CLICK ON + SIGN FOR NEW SURFACE DAM SURFACE STILL HAS NO DATA Calculate Volume

  8. RIGHT CLICK ON BREAKLINES SELECT DEFINE BY POLYLINE Calculate Volume (Cont.)

  9. ENTER A DESCRIPTION FOR THE LINES OF THE STRUCTURE Calculate Volume (Cont.)

  10. Calculate Volume (Cont.) SELECT THE LINES THAT WILL MAKE UP THE NEW SURFACE

  11. Calculate Volume (Cont.) SELECTYES, AUTOCAD CREATES A NEW LINE ON A SPECIFIC LAYER

  12. Calculate Volume (Cont.) NEW DATA EXISTS FOR THE BREAKLINES SELECTED

  13. Calculate Volume (Cont.) RIGHT CLICK ON NEW SURFACE, SELECT BUILD

  14. Calculate Volume (Cont.) CLICK APPLY EDIT HISTORY AND SELECT OK

  15. Calculate Volume (Cont.) WITH ANY LUCK YOU WILL SEE THIS MESSAGE. SELECT OK

  16. Calculate Volume (Cont.) THE NEW DATA APPEARS. VIEW AND EXIT

  17. Calculate Volume (Cont.) THE LINES ARE ON A NEW SURFACE

  18. Calculate Volume (Cont.) SELECT THE LINE TO VIEW THE VERTICES

  19. CALCULATE QUANTITIES Calculate Volume (Cont.)

  20. Calculate Volume (Cont.) FROM TERRAIN, PICK SELECT CURRENT STRATUM

  21. Calculate Volume (Cont.) “Stratum” refers to use in calculating first surface, second surface and elevation difference. The first surface is the EXISTING GROUND SURFACE. The second surface is the CREATED STRUCTURE SURFACE. Select OK

  22. Calculate Volume (Cont.) FROM TERRAIN SELECT SITE DEFINITION AND DEFINE SITE

  23. Calculate Volume (Cont.) AT SITE BASE POINT, SELECT THE LOWER LEFT HAND CORNER OF THE PROJECT. THE SMALLER THE GRID SIZE THE MORE SAMPLING IS DONE. 2-5 USUALLY WORKS WELL

  24. Calculate Volume (Cont.) THE M AND N REFERS TO THE X AND Y AXIS OF THE SAMPLE BOX 2-5 USUALLY WORKS WELL

  25. Calculate Volume (Cont.) DRAG LINE TO UPPER RIGHT AS TO INCLUDE ALL OF STRUCTURE

  26. Calculate Volume (Cont.) SELECT YES

  27. Calculate Volume (Cont.) AUTOCAD ASSIGNS A SITE NAME, IT CAN BE ACCEPTED (ENTER) OR OVERWRITTEN WITH A NEW NAME

  28. Calculate Volume (Cont.) A BOX APPEARS AROUND THE SITE AS DEFINED

  29. Calculate Volume (Cont.) FROM TERRAIN, SELECT GRID VOLUMES, THEN CALCULATE TOTAL SITE VOLUME

  30. Calculate Volume (Cont.) SELECT THE SITE AND HIT OK

  31. Calculate Volume (Cont.) CORRECTION VOLUMES MAY BE ENTERED FOR CUT AND FILL, HIT OK

  32. Calculate Volume (Cont.) ENTER A NAME FOR THE SURFACE THAT IS CREATED FOR THE VOLUME RESULTS SELECT OK

  33. Calculate Volume (Cont.) FROM THE FIRST METHOD THE VOLUME OF THE CUT AND FILL ARE IDENTIFIED

  34. Calculate Volume (Cont.) TO COMPARE A DIFFERENT METHOD OF CALCULATING VOLUMES FROM TERRAIN SELECT COMPOSITE VOLUMES AND CALCULATE TOTAL SITTE VOLUME

  35. Calculate Volume (Cont.) SELECT THE SITE AND HIT OK

  36. Calculate Volume (Cont.) AGAIN CUT AND FILL FACTORS CAN BE OVERWRITTEN OR LEFT AT 1.0 . SELECT OK

  37. Calculate Volume (Cont.) ENTER A NAME FOR THE SURFACE THAT IS CREATED FOR THE NEW VOLUME RESULTS SELECT OK

  38. Calculate Volume (Cont.)

  39. Calculate Volume (Cont.) FOR A THIRD METHOD OF CALCULATING VOLUMES, (A TWO STEP PROCESS) FROM THE TERRAIN MENU, SELECT SECTION VOLUMES, THEN SELECT SAMPLE SECTIONS

  40. Calculate Volume (Cont.) AGAIN SELECT THE SITE, HIT OK

  41. Calculate Volume (Cont.) AGAIN CUT AN FILL FACTORS CAN BE OVERWRITTEN OR ACCEPTED. HIT OK

  42. Calculate Volume (Cont.) AUTOCAD PROCESSES 100 SAMPLED SECTIONS

  43. Calculate Volume (Cont.) FROM THE TERRAIN MENU, SELECT THE SECTION VOLUMES AND CALCULATE VOLUME TOTAL.

  44. Calculate Volume (Cont.) AGAIN SELECT THE SITE, HIT OK

  45. Calculate Volume (Cont.) AGAIN ACCEPT OR OVERWRITE, HIT OK

  46. Calculate Volume (Cont.) AGAIN THE VOLUMES ARE DISPLAYED FOR THIS METHOD.

  47. Calculate Volume (Cont.) TO GET A PRINTOUT OF THE VOLUMES COMPLETED Terrain Volume Report Site Table

  48. Calculate Volume (Cont.) AGAIN ONE MORE TIME TO ENTER CORRECTION FACTORS, HIT OK

  49. Calculate Volume (Cont.) SELECT THE INSERTION POINT TO PLACE THE CHART (AWAY FROM DRAWING) AT ROTATION ANGLE OF ZERO, ENTER.

  50. Calculate Volume (Cont.)
