Get only the first and last segment of every polyline

Hi,

 

 

The Snipper with the following parameter setting will output the first and the last segments from the Remnants port.

 

Snipping Mode: Vertex

 

Starting Vertex: 1

 

Ending Vertex: -2

Thanks.. it's work for 90% of polyline.. Now when i try to use extend the segment if it has the length les than to 30, I have some problems (it delete the segment and make another one)..  What I have (the first) and what I want (the second) and whatI got (the third)

 

what I want

 

 

 

 

 

 

thanks for help

The 2DVectorCalculator (FME Store transformer) might help you.

 

You can also get a bit of the end and start of a line (using snipper).

 

Then get their angle (ie.. with azimuthcalculator)

 

 

Extract 1st coordinate of endpiece and lastcoordinate of endpiece.

 

 

Use affiner to move them with your required distance (30 in your example).

 

Affiner settings would be 1,0,  30*cos(angle) and 0,1,30*sin(angle)

 

direction of move: to extend it, it is positive. to reduce it, it is negative.

 

Now you can connect thes new points at the end of the linepieces.

 

 

Then

thanks Takashi and Gio.. I will try your idea on monday.. For now I used to take a 30m segment from every line by adding measure and take 0-30 from the start and 0-30 from the end.. it's not which I want but it works.. I will continue to trying and write again

Hi, I got it with 2DVectorCalculator.. thanks alot
