Points by elevation,distance, and along path

I would like to create points using LDD.

I need the points to be exactly 25' apart, interpolate
between two elevations from one end of a line to another, and follow the path of the line which includes an arc...all at one time.

How can I do this quickly?

Nexus/lexus:
The 'measure' command almost gives you what you want. It places points along a line/arc/pline at intervals you specify. If you had a 3-d line or arc the points would be placed at a 3-d spacing and would vary in elevation per location on line. So you could pre-calculate the required 3-d spacing that would give you correct 2-d spacing, then use that spacing with Measure. But if you 'Measure' an entity of constant elevation, such as a 2-d polyline, the points will be placed correctly but you'd have to manually set elevations. Depending on your needs, a custom routine may be called for.

I always used the divide command. Make your line in 2D or 3D, then devide it into the the number of segments you want. Erase the line and you have nodes at the break points.
