I'm assisting a hydrographic surveyor to plan for plotting in AutoCAD. The survey spec has a requirement for a plot of soundings on a 4m x 4m grid with contours, that's fine and no problem we've done this numerous times before, but there's also a requirement for a plot with the soundings and contours banded in to different colours, eg 0 to 1 will be red layer, 1 to 2 in orange, 2 to 5 in yellow, 5 to 10 in green and so on. Does anyone know of a software package or add on that will sort our file of all points by depth bands into layers? We did this once before by sorting the file points by depth order and creating individual files for each layer but it took ages.
Civil 3D does this:
On the Analysis tab, change the Analysis type: to Elevations. Choose number of ranges and click the down arrow to create ranges in the Range Details area. To change the?ÿcolours simply click on the coloured area in the Color Scheme column

Thanks Radar, I should have explained myself better. Attached is a copy of a portion of a typical survey in the format that is required. The grid of soundings is extracted from multibeam data and the sounding values are colour coded for the various depth 'bands'. It's a bit time consuming doing this manually.
I used the Query Builder located in the Point Group Properties to achieve something similar. In the attached, I created 2 points groups "Red" and "Green" then I set a condition in the "Red" group , using the Query Builder, to only include the points if the depth was less than 10' and for the "Green" group the condition was to only include points that were more than 10'.?ÿ
Make point styles for each band, then make a point group for each and then use Include, "with elevations matching" - you can put in a range, like this one where I put 5-6, i.e. 5 to 6m.
