Stop making a line at point without an attribute

[MateuszRatajczak]

Hello, I have a set of data with XYZ coordinates. I want to make a line from start to the end, but some points are missing Z data. The Question is. is there a tool or a script where Point to Line will stop at a point with now data and continue from the next one with full XYZ?

I don't want this interpolation to cover the point without full XYZ data.

Any help is welcomed!

Sounds like you will need to investigate some python / arcpy magic.

If you can post an example of your data here maybe someone can get you started.

Other info required : what version are you using and what is the coordinate system of the data?

A quick search revealed thing like this :

python - Reading Text File to create Polyline with ArcPy? - Geographic Information Systems Stack Exc...

So we use CRS - EPSG 3334: Pulkovo 1942(58) GaussKruger Zone 4 and ArcGIS 10.2.

Want I'm looking for is a line that will break each time there is a gap.

[JohannesBierer]

Why not creating two lines? One line with the full data, one erase line with the data without z information? Then erase the no data line area?

[NeilAyres]

Is that 3rd column (3, 4, 6, 8 etc) a line identifier?

So line 3 would become 2 pieces but the same line ie multipart.
