sweep profile - always vertical to the sweep path
In my district, we have to make our buildings comply with daylight recession planes.
basically the buildings cannot intrude above a theoretical recession plane, 2.5m above the site boundaries at 25 degress coming back into the site.(this give the neighbors a gauranteed sunlight)
I have tried modelling this recesion plane in revit using a sweep (create a grid along a property line, Section it, create a sweep path along a sketched topo, draw the sweep profile in the section & then finish it)
problem is, the recession plane created using the sweep profile is perpendicular to the sweep path - alright if the property is flat but on steep sites the sweep created is not vertically above the boundary, its perpendicular.
dose anyboy know how to create/rotate a sweep profile so that it is always located vertically?
Cheers
