Message	1. What should I do to attach the table with coordinate to get a point shapefile with this localisation. when I use "Add XY data" I can't direct the X, Y coordinates from my table. The table is .dbf (IV). 2. Is there any simple tool to calculate the lenght of line features? Thanks for anserws.

Message	1. Make sure that the fields containing your coordinate information are numeric (they'll have to be in decimal degrees if they are geographic) otherwise they won't be an option for add xy. That may be your problem. 2.For finding the length of line features, there are several options. Simply storing the lines in a geodatabase is best, as geodatabases automatically display a Shape.length field that is updated as features are edited and processed. If you don't want to use geodatabases, there is a Calculate Geometry tool available. Just create an new Double field in a line shapefile, right click the field and choose "Calculate Geometry". Then, simply select the measurement you want and the coordinate systems, and ArcGIS will update your field with current line lengths. I don't think this updates automatically, though, so periodic maintenance may be necessary.

Message	Ad 1. Ok, perhaps this is the crux. Thus my current problem is to adding numeric column to my .dbf table. When I try to do it, I've got only option of: short/long integer, float, date, double, text, blob, guid. There is no way to add numeric type of data. Do you have any idea what is the reason? Ad 2. Method with convert to geodatabase worked very well, but I have a problem with finding command "calculate geometry". I would be gratefull If you tell me more about it. regards
