Making measurements
The covered distance measurements are
Euclidean covered distances measured in
the world plane. These covered distances are meaningless unless the world plane
(reference plane) has been identified with the
Reference plane tool.
By moving one or more of a curve's handles, the
measurements will be automatically updated to accommodate the change. The
same is true if the reference plane is changed.
