This article explains how to export a file as an STL from Rhino. When uploading a model in the SimScale platform.
- Select the parts desired to be exported.
- In the File button, click on the Export Selected.
- Select STL(*.stl) on the Save as a Type Input box.
- Open the options menu.
- Set the STL Export Options as an Ascii File type.
When the model is going to be studied with a Pedestrian Wind Comfort (PWC) analysis, it is advised when exporting a model as an STL file, to use the following settings as a starting point:
Note: The above settings are coarse, and therefore large surfaces will be low in polygons to reduce the upload size. If the settings make details look too tesselated, then you can use finer settings on specific objects by converting them to a mesh before the export. The above settings are assuming the base unit is meters, but you can multiply by a thousand (x1000) if using millimeters.
Typically, an STL will be much smaller than half a gigabyte (0.5Gb) and therefore, if the file is much larger please consider the details you are exporting and if doing a pedestrian wind comfort analysis refer to the basic geometry requirements or if any buildings originated in Rhino or similar BIM software, please see our Revit preparation guide.
