Something I have been meaning to do for a while.
The tadpole symbol I have in the UKIE country kit upto 2012 was a bit poor and also not set up to draw in separate colours for cut and fill as I am sure most of us plot in colour.

So here you can download the sample file with some new styles in there ready to drag and drop into your own template. (made in 2011 version)
Download Cut and Fill Tadpoles (Right click on the link and 'Save As')
Here is how you can use them.
For corridors, using the ‘Slope Markings’ tab of the Corridor Properties, you select two feature line codes to use to draw the tadpoles to.
You select these lines in the plan view, so make sure you have them displayed.
So in this example, I want to select the corridor feature line on the back of footpath and then the daylight_cut or daylight_fill

When you select the lines, if there are multiple lines drawn close or on top of each other you get this selection box

Choose the cut or fill so that the tadpole can react appropriately for colour

You need to do this for both cut and fill and sections of the corridor.
Choose the cut or fill tadpole style

For colour control for these, the blocks are placed in C-TADPOLES_Cut and C-TADPOLES_Fill layers.
Within Grading, Cut and Fill is automated via a Cut and Fill style.
These again use the same slope marking symbol style as the ones above.
The only difference is that you might want a small spacing of the tadpole symbols to be placed.
So for this in this file there are two versions of the tadpole style,

So you can see here where you control the distance and also the length of the line that extends from the block to the daylight line.
You may need to tweak this values to suit your project to get the best effect.

Hope it helps
