Picking a station along a curve - AutoCAD

Recommended Posts

I have a paper plan set of a sidewalk that contains several simple horizontal curves. I've managed to use the curve data to replicate the sidewalk centerline in my CAD file. The outside edge of the sidewalk is kind of a zig-zag polygon line. To locate change of direction corners in the zig-zag line I was given the location point as a station along the trail and offset distance from trail centerline. My question is how do I easily locate a point along the curve at a specified station.

 

I've managed to do a few using the MEASURE command and I insert a block at the specified station as a distance from the point of curvature. This works, but is very cumbersome and on top of that every time I insert the block it inserts 4 of them at the specified length that I entered.

 

Please let me know if anyone has a quicker method. Also, if you know how to fix my problem with the MEASURE command I would appreciate that as well.

 

Thanks,

I would make an alignment from the centerline. Next use the annotate tab, click "add labels", select "alignment" and choose "station offset" and take it from there.

I don't think LT has Alignments or station offset commands. :)

If its intersection pt relative to a curve then just draw a line from pt "Perp" to arc thats the true pt.
