Hello,i would like to calculate the surface of a dwg plan. My first approach was to make a bounding box and calculate the area but it's not precise enough.
I was wondering how i could do something like that :
The blue line is at 4 meters of the feature ....
I hope you see what I mean , and hope that you could help me.
Thanks a lot.
Best regards.
Steph.

I thought to that possibility but the thing is my drawing is made of thousands lines and I want that the most outside lines define the "polygon area"...
as you see in my drawing (sorry I'm not autocad drawer) the black lines are my features and I want to get a polygon just as the area inside de red lines

Ok, if your data is like that then a hull accumulator might be a better possibility. You could still use the bufferer but you would need to dissolve afterwards. Or you could aggregate then buffer.

Thanks for this info.
I didn't know this transformer.
It's a bit more what I want to achieve....
If i could reach the red line area,
it would be perfect !+44Thanks for this info.

+18Hi @stephanemarly,
It think the buffer approach might work if you aggregate your features into one feature using the aggregator transformer and then buffer it and calculate the area.
Hopes this helps,

+12If you first aggregate your features with the Aggregator and then use the HullAccumulator transformer you might end up with a result that is useful for this purpose.
