Chapter 1SurveyingPart 650Engineering Field HandbookFlorida SupplementSECTION C3: CIVIL 3D DESIGNPROCEDURESThe use of AutoCAD Civil 3D can provide the usergreater efficiency when downloading, processing,designing and plotting data. The procedures asdescribed below can be used when creating a Surfacefrom Survey points, creation of an Alignment,Profile, Sample Lines, and Cross Sections. Theprocedures also describe the use of Surface Editingtools, Grading tools, Design Corridors, Designprofiles, Surface Volume Tools and exporting andimporting design files.This procedure assumes the user has a basicunderstanding of Civil 3D tools. If a more detailedexplanation is required, refer to the online ReferenceGuides (RGuides) located atwww.nrcsknowledge.comC. Highlight the header “Point Groups”.D. Right-click and select “Update”.Before using these procedures, user should makesure the following programs and files are up to dateon computer. Compatibility issues may arise if anyprogram is not up to date: NRCS Civil 3D files – several features havebeen localized from National Headquarters Civil3D template including all of the Florida Surveycodes, Coordinate systems, and Styles Windows Mobile Device Center Program – usedto link external devices such as Data Collector(TSC3) data collectors and various TotalStations. Geoid Model files (GGF) installed usingAutoCAD and Trimble Link menu fromCivil3D. (An IT specialist may have to do this)I.CREATING A SURFACE USING POINTGROUPSA. Select the “Prospector” tab in theToolspace.B. If the “Toolspace” on the interface is notshow, open by typing “SHOWTS”E. Point Groups are now populated. Creating asurface requires the addition of point groups.A point group is a filtering processAutoCAD uses to filter survey codes such asNG, and or BM. The NRCS template is setup to filter the Survey Codes ONLY.(210-vi-EFH-Florida Supplement April 2016)FL1C3 - 1

Chapter 1SurveyingPart 650Engineering Field HandbookFlorida SupplementD. Give the surface a name by clicking insidethe values box where it says “Ognd”.Rename it and then click “OK”.II.CREATING A SURFACEA. With the survey imported and point groupsupdated. Go to the “Prospector” tab.B. If the “Toolspace” on the interface is notshown, open by selecting it from the menu(“General” “Toolspace”) or by typing in“SHOWTS”E. Next open the surface header. Select theexpansion icon (small plus sign) next to“Surfaces”. The new created surface willappear under the “Surfaces” header as thename that it was given.C. Right click “Surfaces” and select “CreateSurface ” from the list. A USDA/NRCStemplate may have a surface ready for use.FL1C3 - 2(210-vi-EFH-Florida Supplement April 2016)

Select the next points of the feature line andselect the elevations for each point. Featurelines can be easily modified using buttons onthe “Feature Line” toolbar. An elevation isnot necessary for each point. A line segmentcan be a specific grade/slope or the point canbe placed on the surface.Part 650Engineering Field HandbookFlorida SupplementE. The feature line has now been completed. Itwould be beneficial to explore the“Features Line” toolbar in order to explorethe functionality of it. Editing elevations,filleting, quick profiles, and splines are just afew of the abilities of the toolbar. Featurelines can also be created from polylines. Thenext step in determining the earthworkvolumes of a project is to create a gradingfrom the feature line to the surface.XX. CREATING A GRADING OBJECT FROMA FEATURE LINEGrading consists of defining a baseline with someelevation and criteria for defining the projection. Thecriteria used consist of a target: surface, elevation,relative elevation, distance, slope, or grade. Thefollowing procedure will create a 3:1 slope for theembankment feature line previously drawn.A. To create a grading click on “Grading onthe home menu and select “Gradingcreation tools”.
