    Default Drawing polylines with specific angles

    Hi
    I am a geologist, I have some drill hole data.

    I would like to draw the direction of drillholes (collar) using the polylines.

    Is it possible that I can draw polylines with specific angles i.e., 0 degrees (north) , 90 degrees, 75 degrees etc. This way a polyline would orient exactly the same way as the angle mentioned.

    I tried to use direction/length option (this option comes when I right-click the polyline while drawing it) This option does not allow to choose the angle. I am not sure how to use this option properly. Please suggest.

    Thanks,
    Yask

    I am not sure if your polylines already exist and you just want to rotate them or you have points as starting points to draw or create the lines.

    If you are asking a drawing question (using points as reference?), you may want to post this at the Cartography forum:

    If you need to create polylines with bearings, you can try Bearing Distance To Line (new in ArcGIS 10):

    You need to prepare the required fields in a table as input.

    Thanks I think "bearing distance to line" worked for me.

    I entered the UTM coordinates, length and bearing, and it worked perfect for me. Now its possible to draw the lines according to the collar (strike) of the drill hole

    Thanks
