Hi, please add possibility to automatically save line length or polygon area as attribute for feature
thank you for an idea. There is already plan to create 'function attribute'. This would be special attribute with computed value based on other attribute, but the basic goal is to support mentioned length and area values.
circumference of geoobjects would also be very useful...
I'd like to inform that this option is already available (in several last versions) in LocusGIS as "Feature properties" attribute (layer >settings > attributes > PLUS > select Feature properties type).
