I’ve been wondering, in an attempt to further facilitate the workflow between survey and bioclimatic analyses, whether it would be possible to close topographical contours with a boundary line. this might be too arbitrary because I presume it’s hard to tell Grasshopper which side to close the conutour with the boundary intersection while preserving the integrity o fthe topography (ie. the correct direction) without selecting that manually for each contour? can’t sort boundary trims by legnth, distance or height, as those are arbitrary…
I’ve done the initial work, ie. using a script (not included) to move the contours up to their correct height, making them fit/triiming to boundary extents and intersect with the boundary outlines.
(This is so that I have solid closed breps of each topographical layer in order to run shadow study for each topographical layer and then combine them unless someone knows how to perform the year’s soltice shadow studies of a terrain mesh on itself?)
Thanks in advance!
