Either select the Edit Calculation Points command followed by the calculation point family marker of interest, or select the family marker(s) in Revit followed by the command button on the toolbar. You can select multiple calculation points grids using the Multiple option from the toolbar, or, you can select the markers in Revit and then click on the main Edit Calculation Points button. It can also be handy to window across a number of marker instances and use the Revit Filter command to only select "Generic Models".

When a calculation point family marker is selected, the same dialog used to set the calculation point parameters originally is presented to make any required modifications. If you have selected multiple boundary types (Rooms and Regions for example), any changes made will be applied to all boundaries.

When calculation point parameters are changed, the calculation is invalidated and the edited grids must be recalculated.

When a previously calculated point family is selected, the calculation results will appear in the edit dialog. Statistics are shown in the Statistics section on the left and point by point values in the viewer on the right. The "Calculated" field will display the time and date of the last calculation.

If you have selected multiple Metrics (illuminance, luminance, etc.) to be computed for the subject grids, you can switch the viewer display between the different metric results. Open the Metrics section and click the View button for the grid of interest to be displayed.

Selecting Planar Face points

The Planar Face calculation points family marker may not be visible in every view. The default height of the family marker is 7.5' so the marker is typically visible and selectable in a ceiling plan or floor plan view with default limits. If not visible, it may be easiest to select the family marker in a section or 3D view. If the points are on a desktop they may be visible in a floor plan view but not a ceiling plan view due to clipping planes for these views.

Adjusting Decimals, Text Size and Marker

ElumTools uses Revit's Analysis Visualization Framework (AVF) to visualize calculated results. You can adjust the precision of the displayed value in decimals, the size and font of the illuminance points, and the size, shape and color of the point markers from the view property: "Default Analysis Display" (or indirectly from "Analysis Display Settings"). ElumTools ships with a default analysis display titled "ElumTools YYYY". You can edit this as required from the Analysis Display Styles dialog shown.

The Color and Legend tabs in this dialog allow you to control the assignment of color gradient or range assigned to the point markers and their legend properties.
