Determining length of point along a pline

    I have serpentine pline representing the centerline of a walking trail. Is
    there a method or routine in AutoCAD 2K2 where I can easily identify a point
    along the pline to a specific distance (example: 50' of travel from the
    start of the pline, etc.)? Any ideas short of exploding the pline and
    adding segments up manually would be appreciated.

  2. copy the pline and use the lengthen command
    Command: LENGTHEN
    Select an object or [DElta/Percent/Total/DYnamic]: TOTAL
    Specify total length or [Angle] <1)>: 50'


    Ta da...

    Or use MEASURE... (make sure pdmode is something other than 0 to see the
    results)

  3. Try MEASURE (make sure you have your Format > Point Styles setting so you
    can see the the POINTS aka: an OSNAP NODE) and make sure you select the near
    the end of the pliNE you want to start the measure from.

    Use the MEASURE command.

    There you can specify a distance, than AutoCAD creates every unit a point on
    your pline or spline.
    Check that your point style and point size is configured.

    if you check out the free downlods section at www.resourcecad.com there is a routine called POO (honest !) ~ Point On Object ~ this will allow you to place a point on acad objects by using either lengths, percentages of length or start, end, midpoints etc

    The MEASURE command works great. All these years, and I never knew it
    existed.

    Good thing I haven't designed many circuitous walking trails. But hey, now
    I'm ready for the next one. Thanks.

    Assuming that you don't have to do this for many points, just break the pline at the point, select the partial pline, and read the length from the properties window. A couple quick undos restores the original pline.

    If you have to do this with MANY points, you really ought to be working in Land Desktop or Civil 3D, where you can make an alignment from the pline, and then query the station and offset of any point on or near the alignment.

    Sorry about that...the title of my original post was fairly erroneous in
    persepective, though I didn't catch that until I reposted a day or so later.
    What it should of said was 'finding the points for given travel distances
    along a pline/spline. Sometimes what I want to say and what I actually type
    are two very different things.


    pline at the point, select the partial pline, and read the length from the
    properties window. A couple quick undos restores the original pline.
