Sample a surface profile with offset samples. Using surface data to create dynamic sampled profiles is an important advantage of working with a three-dimensional model. Quick viewing of various surface slices and grip-editing alignments makes for an effective preliminary planning tool. Combined with offset data to meet review agency requirements, profiles are robust design tools in Civil 3D.
Master It Open the MasteringProfile.dwg file and sample the ground surface along Alignment A, along with offset values at 15′ left and 25′ right of the alignment.
Lay out a design profile on the basis of a table of data. Many programs and designers work by creating pairs of station and elevation data. The tools built into Civil 3D let you input this data precisely and quickly.
Master It In the Mastering Profiles.dwg file, create a layout profile on Alignment B with the following information:
| Station | PVI Elevation | Curve Length |
| 0+00 | 812.76 | |
| 1+45 | 818.59 | 250′ |
| 5+22 | 794.48 |
Add and modify individual components in a design profile. The ability to delete, modify, and edit the individual components of a design profile while maintaining the relationships is an important concept in the 3D modeling world. Tweaking the design allows you to pursue a better solution, not just a working solution.
Master It In the MasteringProfile.dwg file, on profile B insert a PVI at Sta 3+52, Elevation 812. Modify the curve so that it is 100′ and then, add a 175′ parabolic vertical curve at the newly created point.
Apply a standard label set. Standardization of appearance is one of the major benefits of using Civil 3D styles in labeling. By applying label sets, you can quickly create plot-ready profile views that have the required information for review.
Master It In the MasteringProfile.dwg file, apply the Road Profile Labels set to all layout profiles.
