A survey acceptance rule is a feature in DeviCloud that allows users to set a tolerance of accepted deviation from the drill hole plan either as a percentage of hole depth or as a fixed value. Once set, an acceptance region becomes visible in 2D and 3D plots in DeviCloud.
Types of survey acceptance rules
Tolerance region is presented as a cone shape when setting a maximum percentage of deviation from depth
Tolerance region is presented as a cylindrical shape when setting the maximum deviation as a value
Acceptance rule hierarchy
Acceptance rules are inherited down from a site, project, drill program and to hole. An acceptance rule on a lower level will override any acceptance rules on higher level.
Therefore it is recommended that general rules are set on the site level, with more specialised rules being set on each project, drill program or even on every single hole.
How to set a survey acceptance rule on a site/project/drill program/hole
To set a survey acceptance rule, go to the site/project/drill program/hole you wish to set the rule on and navigate to the bottom of the dashboard. Here you will find the Survey Acceptance Rules Settings.
To add a rule, select 'Add rule'. Select type of rule and enter in your chosen value. In the example below a 5% maximum deviation from depth rule has been specified.
Immediately after defining or changing an acceptance rule, the 3D plot will be redrawn to reflect the new acceptance rule. It is possible to visualise the acceptance rules on all holes in a drill program, a project or in a site. However this may affect server and load speed when many holes are being viewed, so it is recommended that acceptance regions are toggled off on higher level dashboards.

Survey acceptance rules: calculation results
Currently there are three calculation results related to survey acceptance rules. These are visible in the 2D plots and in results tables:
Distance to plan
Accepted distance to plan
Distance to acceptance boundary. Positive means inside tolerance (accepted), negative means outside tolerance (not accepted).
QA report (table results):
2D plots:
Please note: QA reports (Cover Sheet) don't currently include these results, however support for this is planned in upcoming versions.
