I have a series of polylines, these represent various linear landscape features (Roads, hedges,rivers). I need to convert these to a series of points equally spaced (so hedges a point every 2m, a river a point every 5m etc) in order to model them in a 3D programme.

How do I do this - I have done it previous in Arc3, but using 9.3 now and lost.

Thank

You could use ET GeoWizzard. Convert -> Polylines to Points or Polyline -> Split. Not sure if this feature is for free, some are entirely for free, some other features are free to use up to 100 objects.

Edit:

You can also try this code. I did not test this.

I have ET Geowizards :) but have been searching for an easy way to do this in Arc owing to the vast number of linear features I need to convert - intending to use ModelBuilder. Thanks for the reply! –  HappyMapper Feb 2 '12 at 11:17

It's an out-of-the box feature in version 10 where you would use the Construct Points function on the Editor menu to create points along any line.

I can't think of a way other then doing it progrmatically in version 9.3

not as good as user21068's answer. See below. ironically the most downvoted answer –  ndthl Sep 15 '13 at 9:18

Add your polyline feature(shapefile) to arc map, add an empty point (shapefile) both files have to be in same workspace(folder). Then start editor, set point shapefile as target, then select poly line feature using selection tool available with editor toolbar, then click editor drop down menu, choose divide, then provide your required interval in " Place points separated by every .... Units). New point features will be created along polyline at specified interval

Tested in arc gis 9.1 , 9.3

in arctoolbox use: editing tools/densify then convert feature vertices to points (data management tools/features)

This answer has been flagged up as low quality due to its short length and someone has already downvoted it. My recommendation is to quickly expand upon your answer, perhaps by listing the steps and using links to the relevant tool help. –  PolyGeo Aug 14 '13 at 21:55
    
It's a pity, too, because this is a really good answer. I think it is much better than construct points option which requires a target points feature class and can't be done in model builder. It's pretty easy to do what @user21068 says. I don't think it needs any expansion. It should be listed as the answer to the question in my opinion. –  ndthl Sep 15 '13 at 9:17

I haven't used it myself, but I believe linear referencing would be the best way to achive what you want. http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/What_is_linear_referencing/003900000001000000/

For ArcMap 10.x users: If you have many different polylines you'd want to dissolve the lines first before using the construct points function. This way the whole dataset becomes one polyline, so you don't have to do each polyline manually.
