To edit GD&T/ datum  symbol parameters, position, attachment or to set or break the relation between a GD&T/ datum and a drawing dimension, use the command "EFO: Edit GD&T Formlimits":

Using together with the pressed key <Shift> adds an element to the list of selected ones, while with the pressed key <Ctrl> - removes from the list of selected elements.

For multiple selections, you can use the options:

       <P>        GD&T Formlimit Parameters

       <Alt+P>        Copy properties from the existing element

       <Del>                Remove selected elements        

       <Esc>        Cancel selection        

When selecting one element, the following icons become available in the automenu:

       <P>        GD&T Formlimit Parameters

To change location and snapping of the tolerance/datum, it is necessary, after element selection, indicate the marker of the desired snapping point with the help of . The selected point will start dynamically follow the cursor (according to the snapping method selected for the point). At the same time the additional options will appear in the automenu:

Pressing will fix the new location of the snapping point of the tolerance. It is possible to change location of any bend point exactly in the same way. It is also possible to cancel snapping of the point with the help of the option, snap tolerance to a node or line, specify/cancel relation with dimension.

To remove one of the arrow-extensions of the tolerance, it is possible to use the option. If the tolerance/datum being edited has only one extension, then this option is available in the automenu right after selection of the element being edited. In case if the tolerance/datum with several extension lines, the option will become available after selection of the desired extension line. The extension line can be selected in the command’s properties window (the “Arrows” section) or, for example, by specifying its starting point in the drawing’s window. To remove the extension line, it is also possible to use the button next to the list of arrow-extensions of the tolerance/datum in the command’s properties window.

The option allows modifying the parameters of the selected GD&T symbol notations. Modifying the parameters in the case of a single selected element is similar to original defining of the GD&T symbol parameters.

In the case of multiple selections, calling the option <P> brings up the dialog box "GD&T Formlimit Parameters". All parameters of the selected elements are subject to editing.

       

The option <D> allows setting the relation between the selected GD&T symbol and the desired drawing dimension. To delete the selected GD&T symbol, press the key <Del>. To select and modify parameters of a group of GD&T symbols, use the same techniques as for other elements.
