Question

LineCombiner and MRF2DJoiner seem not to work properly

Hello,

 

I have a shapefile where some connected lines have to get connected and merged into one feature.

 

However, it seems like there is a problem in my use of LineCombiner and MRF2DJoiner.

Here is my shapefile :

Attached : a picture of a linear feature who has passed through the LineCombiner but still divided in 2 llines altough there are both connected.

 

Thank you.

Is it possible that there are minuscule rounding errors between the line connections?

Before the LineCombiner, try inserting a Snapper with a suitable tolerance, set snapping mode to "End point snapping" and see if that makes a difference.

How are the lines oriented? Have you set "preserve original orientation = No" in the LineCombiner?

 

Have you set a Group By?
