as info :arrow symbol and line connects to has the same id

Hi @gogopotter90 ,

If the arrowhead always consists of two lines shorter than the shaft, an easy way is to calculate length of all the lines with LengthCalculator, sort them by length descending with Sorter, and select the first one for each identical ID with Sampler or DulicateFilter.

i have tested before but I have still no luck .

Bcs some of them is connected as arrow head and line (as one object )

so if I want to calculate the length ,it calculate for the whole line with arrowahead .they are not seperated .

You can use Chopper (Mode: By Vertex, Maximum Vertices: 2) to separate an arrow shape into individual line segments.

Thanks I will try it

is there possible to use azimuth calculator ,to find the arrowhead depends on the angle ?

If the azimuth of arrow shaft is known, you can determine if a line segment is a part of arrowhead based on its azimuth.

If you calculate azimuth for each line (arrowhead x 2, arrow shaft), it could be possible to determine if which one is the shaft.
