Hannes Löschke replied to MtoM's discussion Extrude Building Outlines to z Point Heights from GIS

"This is pretty much what I did. My version just sets the z coordinates to 0 by exploding the points and rebuilding them without the z. This might produce slightly less overhead than projecting the points to a surface. I'm using 0.9.0014 so…"

"Thanks, that's a pretty clear explanation. I think I'm missing something obvious about sorting lists. I've gotten as far as getting the non-z pts on the same xy plane as the centroids, and found the closest pairings using the…"

"I haven't opened the files because I'm not in my working computer, so I'll try and explain it. From what I have read, can't you just project the point which has the z-value (height of the building) and the points that have the…"

"This is as close as I can get without opening your gh file. I may be on the wrong track. I use the PlaneCP(CP) component to find the closest pairings ignoring the z value of the original points. Now I have the correct pairings of…"

Hannes Löschke replied to MtoM's discussion Extrude Building Outlines to z Point Heights from GIS

"You need to find the closest points ignoring the z coordinate. CPs returns not only the closest point but also its index in the list. You can now use this index to select the point from the original list of points with non-zero z. "

Extrude Building Outlines to z Point Heights from GIS

I've put together a simple GH file that extrudes planar building outlines up to the z height defined by the closest elevation point to each outline's centroid out of a field of elevation points. These points started as text objects from GIS data. I converted the text objects to 3d pts using the rhinoscript that Simon Kallioinen posted in another thread. (That script is here http://www.rhinoscript.org/rhinoscript/44) Thanks Simon!My problem…See More

Tower Floorlines Error

Hi Everybody,I'm working on a small definition that seems pretty straightforward. However I'm at a dead end and would really appreciate someone's advice on this. I'm a bit of a newbie still.I want to draw section lines on a lofted brep (of a tower which is in the Rhino file) at every floor level.floor levels are defined by a series of xy planes that have been arrayed up the z axis. Floorlines are being drawn by intersecting the Brep with these planes.It only returns a few floorlines, and…See More
