a software error In the solar access analysis?

In the solar access analysis,if I chose current time/day in the period,then the result could be zero(whatever other options be).
If I chose custom after current time/day,then the result also is zero.but if I chose custom the first time or after all the other period options,the result could be right.
So I wonder whether the current time/day/custom in the period is an error.

Solar Access Wizzard

Yun,

This is what I have noted:

When selecting Current Date and Time, the wizzard uses the right date and time, but there is an error whereas the software will indeed try to calculate the solar access for say 9 am to 9am...which is naturally 0, hence the zero result.

Now if you select For Current Day, the wizzard will, by default, also be set to the same hour-to-hour time range, but here, you can edit the time and select a broader span of time throughout that day, in the wizzard summary. The results will then be > 0.

Using the For Specified Period, you are given the option early on (step 3) to select the time range, so that is not problem.

Let me know if that makes sense.

Olivier

oliver thanks very much
