comment Clipping cross-sections by flood area using ArcGIS for Desktop?
Try changing symbology on your polygon so it is filled. Then you see why. It'll only clip the polygons where one exists. In the areas where you are not getting a line, it's because there aint no polygon to clip.

comment Including labels in map legend and point symbology of ArcGIS for Desktop?
50 colors isn't that easy to distinguish from each other. An even more "cheating" approach would be to add text boxes on top of your legend with numbers, but it'll require more checking that all is correct.

comment What is the fastest way to digitize features on a map?
While not open source nor free, you can use OCAD for that. It has got a lot more sophisticated tools for digitizing (however still manual), at least compared to ArcGIS (which I'm more familiar with). Especially curved lines are better supported. There is a learning curve (!) though...

comment How to fill sinks in DEM with specific amount of water
I don't know of any functions in ArcGIS that can model water volumes, only waterways, catchments etc (which you have done already). For that you need something like Mike Flood. You can, however, from a given volume find out which water level it corresponds to in a specific sink. From that you can visualize the water depth in the area and a couple of more things, but none of that is of much use unless you have done the modelling first.

comment How to fill sinks in DEM with specific amount of water
Do you plan to model in ArcGIS which water level will be the result of a specific rain event or do you get the level from another software and only want to visualize it in ArcGIS?

comment How can i measure the signal strength of Base Transciver Station(BTS)?
Could you elaborate a bit on your question? What hardware and software have you got, what is the purpose, what have you tried/investigated so far, etc? Please have a look at the Tour for further guidance on how to ask a question here.

comment moving points from one place to another on the same layer
So what have you tried, and where do you get stuck? Also add which version of ArcGIS you are using. A screenshot might help explaining as well.

comment How can I write hidden information to a pdf file from ArcMap?
White text is very convenient, haven't thought about that :) However, a lot (most) of these maps will become official government documents and some will even be published online. I also make maps that will appear in court, for different kinds of permits etc. So I'm not very comfortable with adding "visible" hidden text in those files. I should take a good look at the mapping module and see what I can use it for, though.
