The Curtain Wall element attributes and properties can now be edited.Get the latest Archicad Get Rhino & Grasshopper Note that the elements will be locked by default and have to be unlocked by selecting them and going to Edit > Locking > Unlock. The Curtain Wall element will now be generated in ArchiCAD where it can be edited further. Once the settings are determined, double click on the Toggle component to change it to “True”. However, this is not crucial as the curtain wall attributes can still be edited later on. The final step before synchronising and creating the Curtain Wall component is to determine your Curtain Wall settings in ArchiCAD. Ensure that the ArchiCAD Point is on the correct side of the curtain wall geometry by checking the preview in Rhino.

Otherwise, an estimate will have to be made, the Point previewed in Rhino, and adjusted accordingly.Īfter setting the Point component in the ArchiCAD window, the Rhino and Grasshopper windows will reappear. If the Rhino geometry was exported from ArchiCAD, the same ArchiCAD file can be used to set the Point component. The Rhino and Grasshopper windows will minimize and the ArchiCAD window will appear.Īt this point, it is important to determine the position of the element in the ArchiCAD plan file in order to set the reference point for the external side of the curtain wall.

Right click on the ArchiCAD Point component and select “Set one Point in ARCHICAD”. Launch the Grasshopper Connection in ArchiCAD (Design > Design Extras > Grasshopper Connection) and click “Start Connection”.

Connect an ArchiCAD Point component to the “External Side (E)” connectionĪt this point the ArchiCAD Point component and Curtain Wall Boundary components will display error messages as the Grasshopper Connection has not yet been established.

Connect the Brep to the “Boundary (C)” connection.

Connect a Boolean Toggle component to the “Synchronize” connection (make sure it is set to default position i.e.

Step 2: Using Grasshopper Components to Create the Curtain Wallįirst, use a Grasshopper Brep component (Params > Geometry > Brep) to represent the surfaces already modelled in Rhino by creating a Brep component, select all surfaces you wish to use in Rhino, right click on the Brep and select “Set Multiple Breps”.Īfter this is done, drag the Curtain Wall Boundary component from the ArchiCAD tab onto the canvas and: Before proceeding to the next step, ensure that all surfaces to be used are “open surfaces”. Use the MeshToNURB command to convert any mesh faces into open surfaces. Note that the option to save as a Rhino 3D Model (*.3dm) only becomes available when selecting File > Save As in the 3D view pane in ArchiCAD.Īfter exporting to Rhino, the Morph objects will be recognized as “blocks” and must be broken up into their individual surfaces using the Explode command. In this tutorial, the curtain wall geometry used was modelled first in ArchiCAD in order to fit certain elements already present in the model using the Morph tool and then exported to Rhino.

If using ArchiCAD, the Morph or Mesh tool can be used to create the curtain wall form and later exported to Rhino. Important note: The geometry of the modelled elements must be planar otherwise ArchiCAD will not be able to generate a curtain wall element from it. The design of the curtain wall can be modelled in either ArchiCAD or Rhino depending on one’s preference as ArchiCAD 20 now supports the export of the 3dm file type.
