Views from sun

Often when producing a SEPP65 solar access analysis you will want to generate views from the sun to visually verify the results of the Ladybug ‘heat map’. This can be achieved by using the ‘View.FromSun’ custom node from the BVN Dynamo Package.


The custom node utilises the Clockwork (0.90.7) package to calculate the orientation of True North and the Ladybug (0.1.1) packages to generate the sun vector for a given analysis period. Please note that Ladybug currently has a minor bug which results in returning extra dates/vectors from the analysis period. However, for the purposes of this tutorial, this bug is not critical and any additional views can be simply manually deleted as required. Finally, the custom node uses Dynamo’s native ‘AxonometricView.ByEyePointAndTarget’ node to generates 3D orthographic views.


To visually check that the node has worked as intended, you can turn on a view’s shadows and then set the sun settings to ‘Still’ and make the date,…
