How To Transfer Roof Height Information Form Rhino To Gis

Both of these issues rely on information about where rhinos are and why.

How to transfer roof height information form rhino to gis.

Using rhino s patch command we will make a terrain using the altitude points. Buildingfid the building s internal id number. Altitude and station entrance tsv files. The roof form can be flat gable or hip.

Roofform roof form the shape of the roof. I ve been using sketchup to pull the gis data exporting it to rhino as a dwg and then using the contour command to get the contours i need. This creates an x y and z field within the point shapefile. You may see some dips in the terrain where some points have erroneous height values.

This method generates nurbs geometry in rhino allowing you to use features like make2d to export vector graphics. I ve tried using. The problem is that when i try to export the file into arcgis it puts the model in the indian ocean. Import image as plain.

Emslie and brooks 1999. Calculate the elevation field to equal the z field. Most gis building shapefiles have building heights embedded in them that you can tap into with grasshopper to automatically extrude to the correct height. Use the built in.

We will assign the x y z values to all be read from excel. This is accomplished with the raster to ascii tool in the conversion tools from raster toolbox as described in the digital elevation models tutorial. If it doesn t then you can just write a grasshopper script to randomly extrude the curves to a set range of heights to give the appearance of it being less uniform than extruding them all by. Buildings with no eave height have flat roofs.

I m currently working on a project in argentina where i need to extract the gis data to get contour lines of our site. This tutorial will cover some basic techniques for importing gis data into rhino using the grasshopper plugin in order to create a 3d site model with basic building masses. Separate the two layers in rhino as you import. Gis and rhino conservation in situ rhino conservation is based on security and biological management e g.

If the shapefile has a pointz and there is no field that contains the elevation navigate to arctoolbox data management tools features add xy coordinates. Open a new rhino file file new large objects meters 3dm. Then sub divide it 2048 or 4096 times or less if you do not have 32 gigs of ram and add a displacement to it using the height data in 32bit float normalized to 0 to 1 tiff image. The best way to get a gis based elevation model to rhino terrain is by exporting it to an asciigrid.

Using una s import points we will import our point data.
