Distance to Free Face

On the Mining | Blast Design tab, in the Report group: Click Distance to Free Face to check that the designed holes adhere to a specified minimum distance to the free face. If necessary the collar position, inclination and orientation of a hole can then be edited interactively. An annotation of the current distance to the free face is shown.

If not already selected, you will be prompted to select the block or the block objects that contain the holes you want to check.

Free Face Wireframe

Select the type and the name of the wireframe that represents the free face.

You can also use the Pick from Vizex button (or select the context menu option where available) to collapse the form and interactively select the required Wireframe to insert and return to the form.

Distance attribute

Click on the List icon to select an attribute that will be used to write the distance to the free face for each hole.
