Datum Targets
Datum Targets can also be added to a predefined datum feature in order to add user guidance for measurement. These can be important when a surface is irregular and measurements need to be taken in particular locations on the larger datum surface. Datum targets are listed as separate annotations in the tree but must be linked to the same surface as the corresponding datum.
The datum target symbol includes the datum letter and a sequential number to identify the intended order of measurement in the lower half of the provided circle. Datum targets do not currently support entering a proximity tolerance.
Datum targets can be imported with CAD or built within SA. To add a datum target, first clicking on the datum target button in the toolkit and then on the datum feature at the location you would like to identify as the target location.
To more precisely position the datum targets a prompt will also be provided to Select datum target Reference Point. This is optional and pressing enter will add the datum target at click point instead.
