Civil 3D Visualization

  1. 1. Bringing Sexy Back to Civil When 2D Presentation Just Isn’t Enough <ul><li>Larry Young </li></ul><ul><li>Civil Consultant and Trainer </li></ul>
  2. 2. Larry Young Civil Consultant and Trainer <ul><li>AutoCAD version 2 – What Year? </li></ul><ul><li>15 Years Civil Drafting and Design </li></ul><ul><li>10 Years CADD consulting business </li></ul><ul><li>Trainer for: </li></ul><ul><li>AutoCAD </li></ul><ul><li>DCA </li></ul><ul><li>SoftDesk </li></ul><ul><li>Land Desktop </li></ul><ul><li>Civil 3D </li></ul><ul><li>Map 3D </li></ul><ul><li>Google Earth Pro </li></ul>
  3. 3. Agenda Bringing Sexy Back to Civil <ul><li>2D vs. 3D Presentations </li></ul><ul><li>Workspaces </li></ul><ul><li>Visual Styles </li></ul><ul><li>Links and Code Sets </li></ul><ul><li>Feature Lines </li></ul><ul><li>Materials </li></ul><ul><li>Enhancing the View </li></ul><ul><li>MV Blocks </li></ul><ul><li>Move to Surface </li></ul><ul><li>Cameras, Walkthroughs and Rendering </li></ul><ul><li>Preparing for 3D Studio Max </li></ul><ul><li>Importing to 3DS Max </li></ul>
  4. 4. Civil “3D” <ul><li>Civil 3D, as the name implies, will create three dimensional models as you are designing visually in two dimensions. </li></ul><ul><li>The 2D or flat view is not always the best way to present a project to the client. </li></ul><ul><li>3D Views are better, and modeled, rendered with materials utilized make even better presentations. </li></ul>
  5. 5. Requirements for Corridor: <ul><li>The basic requirement for this ability is that the design be done with Civil 3D objects, not AutoCAD primitives. For Corridors – 5 items required. </li></ul><ul><li>An existing ground surface </li></ul><ul><li>A proposed alignment </li></ul><ul><li>Existing ground profile </li></ul><ul><li>Proposed ground profile </li></ul><ul><li>Assembly (or typical cross section) </li></ul><ul><li>Create the corridor. </li></ul>
  6. 6. Create a 3D Workspace and View <ul><li>3D view workflow </li></ul><ul><li>Create a workspace called “Visualization”. </li></ul><ul><li>Add the 3D Navigation and the Visual Styles toolbars to the AutoCAD work area. </li></ul><ul><li>TIP: To display toolbars, right click on any toolbar, or in a blank area in the top of the screen, in the list select the desired toolbar . </li></ul><ul><li>Rotate the drawing up to an isometric view: </li></ul>
  7. 7. Change to Realistic Style <ul><li>Change the visual style to “Realistic” by clicking on the realistic button in the visual styles toolbar. </li></ul><ul><li>This is a bit more realistic looking, but additional modifications are necessary for more realism. </li></ul>
  8. 8. Create Visual Style <ul><li>Open the manager visual styles dialog box by clicking on the button shown. </li></ul><ul><li>Copy the Realistic style: </li></ul><ul><li>Rename to Visualization </li></ul><ul><li>Change Settings to: </li></ul><ul><ul><li>Shadow display: Full shadows </li></ul></ul><ul><ul><li>Edge mode: None </li></ul></ul><ul><ul><li>Apply the new style to the current view </li></ul></ul>
  9. 9. New Visual Style Applied <ul><li>This will remove the TIN (triangle) lines from the existing ground surface, leaving the corridor with links and feature lines displayed. </li></ul><ul><li>These links and feature lines will need to be removed for our visualization style; this is accomplished within the properties of the corridor on the code tab. </li></ul><ul><li>* </li></ul>
  10. 10. Create Code Set and Link Style <ul><li>First the introduction: </li></ul><ul><li>Codes = Cross Sections </li></ul><ul><ul><li>At “Intervals” along Corridor </li></ul></ul><ul><ul><li>Interval controlled by parameters </li></ul></ul><ul><li>Links = Along Corridor </li></ul><ul><ul><li>Flowline </li></ul></ul><ul><ul><li>TC </li></ul></ul><ul><ul><li>Sidewalk </li></ul></ul>
  11. 11. Create Code Set and Link Style (Cont.) <ul><li>Click the dropdown arrow for code set style action, and select “Copy Current Selection” </li></ul><ul><li>On the information tab, change the name of the code set style to “Visualization”, enter a description for the style. </li></ul>
  12. 12. Create Code Set and Link Style (Cont.) <ul><li>Select the Codes tab. </li></ul><ul><li>Click the style picker button on any link. </li></ul><ul><li>This brings up the “Pick Link Style” editor box. </li></ul><ul><li>In the Pick Link Style dialog box, select the action dropdown arrow, then select copy current selection. </li></ul>
  13. 13. The Invisible Link Style <ul><li>Name this new link style: _Invisible </li></ul><ul><li>Turn off the link lines for viewing in 3D views </li></ul><ul><li>On the Link Style dialog box, make sure the view direction is set to “Model”. </li></ul><ul><li>Turn OFF the light bulb for the component link by clicking on the bulb icon in the “visible” column. </li></ul>
  14. 14. All Links set to Invisible <ul><li>Select all link lines, click on any link style picker buttons, change the style to “_Invisible” and click OK. </li></ul><ul><li>All links styles should now be set to _Invisible. </li></ul><ul><li>Verify each of the links render material as these are what creates the render style. </li></ul><ul><li>Change or set materials as needed. </li></ul>
  15. 15. Point Markers and Shape Styles <ul><li>Set all Point markers to the “No_Markers” style. </li></ul><ul><li>This will turn off the symbols at each of the intersections of link lines, and feature lines. </li></ul><ul><li>Using the same methods, set all the shape styles to “_No Shading”. </li></ul><ul><li>This will set the shaded cross section areas to invisible. </li></ul>
  16. 16. Turn Off Feature Lines <ul><li>Feature lines still show in the 3D model view and must now be turned off. </li></ul><ul><li>On the feature lines tab in the corridor properties dialog box, select all feature line styles and click a checked box. </li></ul><ul><li>TIP: When clicking the check mark to turn it off, this can take a few seconds so be patient . </li></ul>
  17. 17. Profile Lines in Model View <ul><li>Notice there are two white lines in this example, (they may not appear in your drawing). These happen to be the profile lines of existing and proposed ground. </li></ul><ul><li>They need to be turned off in the model view. </li></ul><ul><li>Note: Do Not turn the profiles off in the plan view. If a profile view of this corridor has been placed on the current drawing, then the profiles will not be displayed within that view. </li></ul><ul><li>* </li></ul>
  18. 18. More Realistic View <ul><li>For a more realistic view, change the model view background to a blue color representing the sky. </li></ul><ul><li>TIP: this is done in the options dialog box. </li></ul>
  19. 19. Creating Surfaces from Corridor <ul><li>To create items acceptable to 3D Studio Max, we must create surfaces from the codes in the corridor (IE: Pavement, C&G, median, ditch, etc. </li></ul><ul><li>Right click on the corridor and select corridor properties. </li></ul><ul><li>On the surface tab, create a surface for each code desired. </li></ul><ul><li>Set the style to triangles, and the Render Material as needed. </li></ul>
  20. 20. Creating Surfaces from Corridor <ul><li>The surface will need to be “trimmed”. </li></ul><ul><li>Create boundaries as necessary for each surface. </li></ul><ul><li>Add the boundary to each surface definition. </li></ul><ul><li>The surfaces are now ready for import to 3DS Max. </li></ul>
  21. 21. Enhancing the View <ul><li>Add Trees and Objects from Tool Palettes MV-Blocks </li></ul><ul><li>Move to surface </li></ul><ul><ul><li>Surface pulldown </li></ul></ul><ul><ul><li>Utilities </li></ul></ul><ul><ul><li>Move Blocks to Surface </li></ul></ul>Optional – Put into 3DS Max
  22. 22. Enhancing the View <ul><li>Trees go into 3DS Max – note: do not always get color. </li></ul><ul><li>Some objects go into 3DS Max </li></ul><ul><li>Surfaces will import to 3DS Max </li></ul><ul><ul><li>Need separate surface for each “sub-assembly” IE: </li></ul></ul><ul><ul><ul><li>Pavement </li></ul></ul></ul><ul><ul><ul><li>Shoulder </li></ul></ul></ul><ul><ul><ul><li>Median </li></ul></ul></ul><ul><ul><ul><li>CG </li></ul></ul></ul><ul><ul><ul><li>Sidewalk </li></ul></ul></ul><ul><ul><li>Create Detached </li></ul></ul><ul><ul><li>Surface from Corridor </li></ul></ul>TIP: Each surface needs to have the material applied in surface properties.
  23. 23. Cameras and Walkthroughs <ul><li>Insert Camera View </li></ul><ul><ul><li>Type the word Camera at the command line. </li></ul></ul><ul><ul><li>Insert the camera location point. (Note: snap to triangle end points get you closer to realistic to start) </li></ul></ul><ul><ul><li>Select the camera by clicking on it. </li></ul></ul><ul><ul><ul><li>Use properties to change Name </li></ul></ul></ul><ul><ul><ul><li>To adjust elevations for: </li></ul></ul></ul><ul><ul><ul><ul><li>Camera </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Target </li></ul></ul></ul></ul><ul><ul><ul><li>Lens Size (28mm good start) </li></ul></ul></ul><ul><ul><li>Also drag “Grips” to edit </li></ul></ul><ul><ul><ul><li>Location </li></ul></ul></ul><ul><ul><ul><li>Field of View </li></ul></ul></ul>
  24. 24. Cameras Preview <ul><li>Live – interactive - as you move camera by grips or properties the camera preview will update. </li></ul><ul><li>Set Visual Style to “See” rendered Visualization style we created earlier. </li></ul>
  25. 25. Camera – More Settings <ul><li>Type “View” at command line </li></ul><ul><li>Select Scene1 </li></ul><ul><li>Set Visual Style to “Civil Visualization </li></ul><ul><li>Set Background override to “Image” </li></ul><ul><li>Browse to “Sky.tga </li></ul>
  26. 26. Camera View <ul><li>Member of the 3D Navigation tool bar. </li></ul><ul><li>Select Scene1 </li></ul><ul><li>Results - 3D View w/ materials, 3D blocks and sky background </li></ul>Capture the image for use in presentation documents . *
