Description
This macro creates a parametric geodesic dome shell. The dome radius and the frequency parameter will be set at creation time.
Temporary code for external macro link. Do not use this code. This code is used exclusively by Addon Manager. Link for optional manual installation: Macro
# This code is copied instead of the original macro code # to guide the user to the online download page. # Use it if the code of the macro is larger than 64 KB and cannot be included in the wiki # or if the RAW code URL is somewhere else in the wiki. from PySide import QtGui, QtCore diag = QtGui.QMessageBox(QtGui.QMessageBox.Information, "Information", "This macro must be downloaded from this link\n" "\n" "https://raw.githubusercontent.com/FreeCAD/FreeCAD-macros/master/ParametricObjectCreation/geodesic_dome/geodesic_dome.py" + "\n" "\n" "Quit this window to access the download page") diag.setWindowFlags(QtCore.Qt.WindowStaysOnTopHint) diag.setWindowModality(QtCore.Qt.ApplicationModal) diag.exec_() import webbrowser webbrowser.open("https://raw.githubusercontent.com/FreeCAD/FreeCAD-macros/master/ParametricObjectCreation/geodesic_dome/geodesic_dome.py")
How to use
1. Install the macro using Addon Manager (menu Tools → Addon Manager). On tab "Macros", pick "GeodesicDome", click "Install". Then close addon manager.
2. Run GeodesicDome.FCMacro. A dialog should appear
3. Specify the parameters, click OK.
a dome shape should appear. You can then edit dome parameters by altering properties of GeoDome object.
Script
(this is an old, non-parametric version of the script. Up-to-date version is in FreeCAD-macros repository, here! )
