Hi All,
I am using MXRoad SS2.
I was trying to change null levels of few points in a string to zero level.
By using minor option 021/022 I was able to do that, but I can do that for single point at a time.
How to change ALL null levels in a string to zero level on one go. The string is having points with other level also, which I dont want disturb.
Thanks in advance.
Regards
Anil
A null level is a special value that MX knows to ignore when creating triangulations, cross sections etc. Say you created a triangulation from a string with four points, and two of the points had null levels (dimension 3 = -999.000). Only two of the points would be included in a triangulation - the two points with the null levels would be ignored.
So null levels are not "wrong" - and they can be very useful. For example, let's say you surveyed the route of a fence which crossed a ditch - if there was a point on the fence string where it crossed the ditch it should have a null level so that it does not distort the triangulation.
thank you sir, then how to correct the null levels using mx......
Wouldn't exporting the strings to AutoCAD 3D polylines convert all -999s to 0.000 but leave actual levels unaltered? Then you could import the string back again...

ok thank u, sir......
