Q: How can I clear all of my features and datum(skew and zero) to start a fresh measuring session?
A: Select any feature in the feature list. You will see a Red X button appear in the bottom right toolbar. Long press this button to delete all features, and to remove all previously performed part alignments.
NOTE: You can also reset the skew and zero without deleting the features by long pressing on the datum indicator found in the top right toolbar(Right Angle icon with the number 1 or 2 in it).
