How to assing classification with segmentation tool

[PablerasBCN]

HI.

The scisors icon segmentation tool has the hability to assign a classification value to the points within the current poliline selection.

Works,

BUT, only works if you've previously segmented any part of teh cloud, like you can not select all and assign a classification value to all area within.

The thing is that I've allready the cloud separeted in individual .las I manually segmented a road.

I know there is the layers plugin, but that requires me to draw over the points and tbh I feel more more comfortable welecting the whold thing with a swquare rectangle and assigning a value manually.

Alternativelly is there a way to clear SF values and assign a custom value to all points? that would also work.

chit chat:
I'm doing this to try to make Kpconv-pytorch work. So far I've spend almost 3 weeks in mastering the data rpeparation script, I'm getting close already... I'll share ressults if I manage to get something worthy.

Cheers!

Well, you can either:
- delete the existing 'classification' SF and then create a new constant one with 'Edit > Scalar field > Add constant SF'.
- or use the 'Edit > Scalar field > SF arithmetic' tool and use the 'set' operation
