In certain modeling instances in ArchiCAD, it may be difficult to model a complex roof structure accurately..
One of the free 'Goodies' Add-Ons from Graphisoft helps this issue by allowing you to model a mesh as the complex structure and then translate all the surfaces of the mesh into roof surfaces.
- Download the ArchiCAD 15 version directly (for Windows) from here
- Download the ArchiCAD 15 version directly (for Mac) from here
- Save the file to your desktop
- When fully downloaded, double-click the file to start installation
- Choose all the default options to complete the installation
- Note the option on the final screen to access the latest Hotfix
The reasoning for this is given on the 'Add-Ons' webpage – the simple explanation is that you must run the latest Hotfix whenever you add a Goodie Add-on to allow the Add-on to be updated to the most current version (i.e. the online add-ons are not the most up-to-date)
Using the Add-On
When installed, the Add-on can be found in 'Design > Design Extras' menu.
With any mesh drawn/modeled in Floor Plan
- Change the default Roof Settings, these settings will be applied to the automatically-created elements
- Select the Mesh (in Floorplan)
- Goto Design > Design Extras > Create Roof From Mesh
- Choose the Roof Settings
- Click OK
Once converted, the individual roof planes can be deleted or edited further, (e.g. their pitch can be modified).
A sample ArchiCAD PLN file (screenshot below), showing a mesh and its converted Roof Structure is available here
