Volume Define Go to Settings > Features, select the feature Polyline then click on Create New button.

Snap on the radius of the first disk that represent the From value (green colour) of the Min variable ofdrillhole - B21955S. 6

Volume DefineVery important note: Remember to move away and back from the working area as you snapto see which disk to snap on. You can only get that indication when the drillhole to snap intois solid.

Release the mouse button then move the cursor to snap on the radius of the first disk that represent theFrom value of the second drillhole.

Zoom in / out to have the other drillholes displayed on the screen by using Alt + Ctrl + the threemouse buttons as you continue to snap to all the From values of all the selected drillholes.
