Hi all, I’m trying to model a large section of a city from a ShapeFile following this excellent tutorial . It directs you to import the SHP file and the DBF table (through Excel), then create boundaries on the SHP curves so as to treat inner openings (courtyards) as part of the building. This should…

I am quite sure there is something on this forum or elsewhere. Some links I found if it could help to explore a bit more ! [image] Building heights trick Hi Djordje, I thought I would share something I have been testing lately. Here in the UK the government has scanned with LIDAR techno…

Hello Laurent! Thanks for your reply! I have visited the links you sent (and many more) but I have not yet found one that touches the specific subject I mentioned (how to tell grasshopper when multiple polygons are overlapping and when they’re actually courtyards - or a way to deal with that in a …

Ok, post some geometry in a file, so we have not to recreate or worse badly recreate it. I am sure people on the forum could help. But I am sure there was a discussion to find very fast if a polygon is inside or ouside a set of polygons. I can’t find it. @lemieszek Here it is [image] …

Hi my friends, I think I have not expressed myself well in the original post. When I import the curves from a SHP file, I get several isolated curves that are not associated with each other. See the first screenshot? I get 9 curves. When I import the list of heights I get 6 values because, as you…

Hello @lemieszek , by any chance you or anyone here managed to resolve this? I have also been trying to extrude 3D buildings based on polygons in shp files, following the same tutorial. But am having problems as the polygons overlap (and also the courtyard issue you mentioned). So any solution/help o…

Hi there, I face exactly the same problem but I would like to extrude a whole city, so I can’t realy isolate the buildings with internal courtyard. The problem I face is that the number of curves of the shapefile are more than the number of heights, coming from the same shapefile. I understand that…

are those two associated? if so why not use the region intersection component?
