Is There any way to add a line/Arrow to Attached at each of my Polygons present in a feature class layer?

Question

The reason i m asking is due to some requirement in a research and analysis where i wanted a vector attached to each of my polygons.The vector can be attached at the mid point or centroid or at the start/End point. Need your assistance on this one. Refer the Doc for more details.

Adding to this is there a way to any one specific side of all polygons in a feature layer?How?

You can replace the current url with the image that symbolizes a vector.

You will need the module "esri/symbols/PictureMarkerSymbol".

The feature layers all will have tables, into which you can calculate geometry values either through arctoolbox tools or using the field calculator.  So it shouldn't be difficult to get the coordinates you need for the XY to Line tool.  I used that example because when you decide which point to use for your start coordinate of the line to make, it is easy to get the end coordinate.  Perhaps to simplify your situation,  choose the centroid as the start point of your line.... get its coordinates (X, Y) within the same file, get the extent height( in Y direction), then make you Xend, Yend equal to ....

Xend = X

Yend = Y + extent_height + 100

In that way the end of your line should be about 100 m above the polygon extent, with some margin for polygon rotation.

Using the field calculator and the tools is way faster than trying to put together a model which you would have to test anyway, so you may as well do it manually unless you intend to use the model every day.

3 was an example,but my data contains 20000 plus buildings and roads present. I have developed many arcGIS models.. but i need some thing to crack the arrow logic.. XY to Line needs table or excel etc not a road feature layer... if i just can have arrows attached to all the buildings and then create an extender model based on buffer??

What do you think?? will that work Dan?
