Where is the cad sunshine analysis of the car?

When CAD opens architectural drawings, it is best to separate the building into a new dwg file for analysis.

Confirm whether the current panel unit is meters or millimeters, and check it in CAD "Format-Unit". The unit here is "meter"

Open "General Plan-Sunlight Analysis" on CAD.

Setting parameters: solar terms-severe cold, and the elevation of the window sill is set to 0.9m (the height between the outdoor ground and the indoor terrace is also the initial height of sunlight entering the window sill).

Select "Calculation-Multi-point Analysis"

Use two boxes to select the building range, and use space for sunshine analysis.
