Taking Sections in n4ce
As with Contours and Volumes a digital terrain model (DTM) may be required. Tools are available for creating, editing and viewing these Models. Sections can be created from feature stings, although a DTM may be preferred. The Lite edition is provided with tools for taking long Sections, with the dialog associated being shown below.
As you can see from the above imagery, sections can be taken through more than one surface, including Groups with depths. The section shown above is a quick view created after indicating the section position.
The quick view can be converted into a drawn section with droplines and text, either in CAD as Model Space as shown below super imposed as a backcloth, or more likely in a Drawing using Paper Space.

Sections can be taken through multiple models either cutting through triangle sides to calculate levels on the profile, or feature strings, or through both. This latter option is particularly useful if you need to show the features that the section cuts through - being plotted on the profile itself.
First, we have to identify where the section is to be placed. A number of options are available here including using previously stored coordinate pairs. The feature option is particularly useful where you are looking for levels along a road centreline defined by a feature. Also, the Lock options work here - as elsewhere, so you may snap to items in a backcloth. |
Having selected the route for the section you will be presented with a view of the section, as shown opposite. This is a viewer and not intended as a final plotted image. The view has a running coordinate and chainage display. You may also zoom, flip and change the colours of profile seen in the display for clarity.
When closing this viewer you will be invited to save this section/s, which then appears on the Project Tree. |

Note in the zoomed view above that there are no overlapping text and that line features that are crossed appear plotted on the profile. What and how it appears in the final plotted section is up to you. We you with the tools and you do the rest! |
Sections can be plotted either in a CAD folder using Model Space, or in a Drawing using Paper Space. It matters not where you display these sections if all you intend to do is plot the resulting imagery on your plotter. It may become an issue if you are passing your client a DXF file and he's not familiar with the model vs. paper space argument! See the section on Drawings.
A number of options are available to you when plotting sections, some of which can be gleaned from the above Section Plot Parameters dialog box. | |
