Need to plot over 500 points at specified distances along a line

[Catherineo_loan]

Hi

I have a list of over 500 bridges for which i need to create a point for each. The bridges lie along a railway for which i have a polyline layer and they are described by their distance from the start point of the railway line..
Is there a quicker way to do this rather  than having to plot each point manually with the construct points tool?

Any help would be greatly appreciated

Thanks

Use Linear Referencing.  All you need to do is use the Create Route tool oriented to the beginning of the rail line to assign measures (stationing) to the line.  Make sure one of the fields of the rail line matches a value in the table of 500 points and that the offsets are in another field.  Use the Make Route Layer tool or right click on the point table and choose make Route layer to position all of the points in a single action.  You can then export the points to a permanent point feature class (events are only in memory in relatiive positions).  That should be it.
