Editing a measurement
You can also modify a measurement at a later stage. You can edit the measurement by changing the polyline shape or its dimensions. Select the polyline and move its nodes or right-click on it to show the shortcut menu, including the options 'Add node', 'Delete node' and ‘Figure data’.
Adding a node
By selecting this option, you will 'Add a node' in the selected closed polygon or polygonal line (polyline).
By clicking on any point in the perimeter of a polygon or a polyline, you can insert a node there. You can then move that node and view the change in the polygon or the polyline.
Deleting a node
By selecting this option, you will 'Delete a node' from the selected closed polygon or polygonal line (polyline). By clicking on any node of the polygon or polyline, you can remove it and view the resulting change in the polygon or polyline.
The measurement result is automatically updated with the above changes.
Measuring length on an image file can only be done using point selection. All other options are disabled.
Figure data
In many measurement types, there are parameters the values of which are different in each node of the measurement. For example, if you perform an area measurement perpendicular to the drawing without specifying a common height, then whenever you create a new node in the measurement polyline, you will be prompted for the value of height at that node. Other examples of this behavior include length measurements with an extra length or manual length input and volume measurements using linear items. You can modify the values of such parameters by selecting ‘Figure data’. Then you can edit the table that is opened, where the nodes are listed in one column and the parameter values in the other. In the previous example, even if you have chosen a common height, you could still edit each node’s height via the same method.
When editing a node, it will be marked on the drawing with a cross (+).
‘Figure data’ is deactivated in length measurements, unless you tick the ‘Extra length’ or ‘Input Segment length’ checkbox, when creating the measurement.
Parameters that are common for a measurement, or a sub-measurement to be exact, can be edited using ‘Edit measurement’. However, once you modify a node’s value by using ‘Figure data’, the parameter stops being common and is no longer visible in the ‘Edit measurement’ window.
