Exercise 3: Working With Crossing Feature Lines - Autodesk CIVIL3D - CIVILDESIGNCOMP 2007 SLM CD Tutorials Manual

3 Click Home tab
drop-down
4 Click the polyline between Circles A, B, and C. Press Enter.
5 In the Create Feature Lines dialog box, under Site Name, make sure that
Grading - Building Pad is selected.
6 Under Conversion Options, make sure that the Erase Existing Entities
and Assign Elevations check boxes are selected. Click OK.
7 In the Assign Elevations dialog box, select From Surface. Make sure that
the Insert Intermediate Grade Break Points check box is selected. Click
OK.
TIP To reduce processing time when working with larger grading groups,
clear the Insert Intermediate Grade Break Points check box. This option adds
an elevation point at each point at which the feature line crosses a triangle.
The polyline is converted to a feature line and breaks the triangulation
along the right side of the ramp. The new triangulation creates a more
gradual slope in the infill area.
To continue this tutorial, go to
Lines (page 415).
