If you have built a design model using Model Builder, you MUST set up your cross section plot to extract sections from the model, rather than displaying design sections using your road template.
Model Builder is becoming a popular command to easily model islands and other features created using strings. The ‘Add Model/Surface’ option when cross section plotting must be used to extract sections and to specify codes to be plotted.
To do this, you need to…
1) Select SET ROW INFORMATION, from the ROW OPTIONS tab
2) Delete the ‘DESIGN SURFACE’ entry – this is used for template-based cross section output
3) Add the entry ‘ADD MODEL/SURFACE’. You need to specify a model created from Model Builder – the prefix of the model must be ‘BM’. If you select a Civil3D Surface, than you cannot control the codes to be plotted.
4) Use the ‘Set Plot Codes for Models’ option to specify the offsets (codes plotted) on the cross section plot. This is the same as setting Plot Y/N when outputting a template-based section.
5) Specify the ‘Line Layer’ to control how the linework is displayed.
6) Ensure ‘Show All Offsets’ and ‘Use All Offsets for Levels’ are turned OFF
7) Select OK to apply. Users do have the option to specify a sample width for left and right, but this can be left to 0.
The software will now extract sections from your model created from Model Builder, rather than displaying the template-based cross sections. It is worth noting that subgrade is not shown when outputting a model-based section. ARD subgrade is calculated from the template. In saying this, there are future plans to be able to create a subbase surface model using Model Builder.
