The AutoCalc command will automatically recalculate all of the illuminance values each time a luminaire modification or calculation modification is applied. This is especially valuable when fine tuning your application. Each time you move a luminaire or an aiming point, AGi32 will subtract the contribution of the old luminaire location and add in the contribution of the new one.
AutoCalc is only available with the Direct Only Calculation method. The reflective or transmissive contribution of objects and rooms are not considered, however, their obstructive capability is considered.
From the Control Bar select 
. To enable
AutoCalc, choose the following option from the Calculate secondary menu:
Direct Only method: AutoCalc On.
