- 1. Introduction to AutoCADand Civil 3D Justin Bonnema, PE USDA-NRCS ANMT Brookings, SD
- 2. Goals for FirstTraining • Increase familiarity with AutoCAD and Civil 3D • Help get you started and enable you to use the programs for what you need them for • Answer any questions that you have • Prepare for more specific trainings yet to come
- 3. Things to KnowAbout This Training • If you have a question – ASK! • There are always multiple ways to do the same thing – use the one(s) that work best for you • Keep in mind the goal of what you are using AutoCAD/Civil 3D for • Use help sources – Online training, AutoCAD help, Google, call trainers • This program can be as simple or as complicated as you would like it to be • Spend time using the program and, whenever possible, with other people who use the program
- 4. NRCS and Civil3D • http://nrcs.rguidelibrary.com/LoginForm.spr – Training by Andrew Walther and Mike Carris • http://forum.nrcsknowledge.com/ – NRCS online CAD community • https://nrcs.sc.egov.usda.gov/st/ndcsmc/CAD/default.aspx – Standard drawings from many states – Getting started videos – Setup instructions for AutoCAD/Civil 3D • NRCS tab/menu in AutoCAD • Drawing templates – National – State customized for waterway, dam, AWMS • License Management – Borrowlicense, returnlicense commands – Or Help (top right hand corner) – About AutoCAD – Product Information
- 6. Options • Type “options”in command line or use application toolbar button • Scroll through different tabs that allow for many options to be changed • Files – reference material locations • Display – how things look • Open and Save – Note the autosave feature
- 7. Customization • AutoCAD andCivil 3D are highly customizable • Use of workspaces and the CUI command • Toolbars vs. icons vs. menus vs. commands • Civil 3D command settings • Templates • Tool Palettes • Properties • Ribbon
- 8. Basic Drafting Concepts •AutoCAD works in 3D, usually view in 2D • Civil 3D allows for automatic updating! • Civil 3D enables planning and drafting of 3D components using grading, corridors, etc. • Surface models constructed from survey points • Layer management has a lot of functionality • Prospector is the main Civil 3D window • Discuss polylines, 2D polylines, 3D polylines, feature lines • Blocks • Snaps, osnaps, grids • Properties window • Tool palettes
- 9. Civil 3D ElementReview • Survey – Manage jobs, figure prefix databases, networks – Automatic linework (figures) • Points – Create points manually – Import points and export points – Manage points and point groups
- 10. Civil 3D ElementReview • Surfaces – Create surfaces – Edit surface models • Raise and lower surface • Paste surface (good for making a stripped surface) – Utilities • Volume calculations • Grading – Make slope projections – Create and edit feature lines – Edit polylines (2D to 3D and 3D to 2D)
- 11. Civil 3D ElementReview • Alignments – Define lines, curves, or geometry to use for profiles, corridors, and sections – Can construct or define from existing polylines • Profiles – Show surface model elevations along alignments (cross sections) – Use profiles for design in the case of corridors – such as in the example of a grassed waterway
- 12. Civil 3D ElementReview • Corridors – Create assemblies for building roads, waterways, etc. – Use for long alignment type applications – Define one or more cross sections for a structural element and apply to an alignment – Corridors can be made into a surface and volumes calculated • Sections – Sections can be used to sample corridors at multiple points – Can generate a volume table
- 13. Civil 3D ElementReview • Pipes – Create a network or pipe system – Requires defining pipe types – Covered in the Dams tutorial • Annotation – Labels can be applied to elements in the drawing • Trimble Link – Import jobs – Export elements to data collector • Points, alignments, surfaces, etc.
