Hello Jason, Here is a guess what might cause your login issues. The login user name for CityEngine is case sensitive, whereas on ArcGIS Online is not. Please go to the account settings in ArcGIS Online check if there are any capital letters in your user name. Then type the name exactly as shown there into the CityEngine ArcGIS Online "Name" field. If you do not use a portal, one can use the standard URL https://www.arcgis.com for login. Please excuse the inconsistent login experience. I hope this will get harmonized in the future. ...

Hi Marek, It is possible to use python to write user set CGA rule attributes to the street segments. The street network can than be written to FGDB. But you have to consider that the CGA rules are applied on the dynamic shapes. CityEngine creates these from street segments and street nodes. This is a 1:n relationship, since e.g. one street segment has a shape with "Street" as startrule and two shapes with "Sidewalk". So, if the left and the right sidewalk have different rule attributes, there will be a conflict. For simplicity I just used the street shape in the example below: from scripting import * import os # get a CityEngine instance ce = CE()     def writeUserAttrToObject(shape,object):        for ruleAttributeName in ce.getAttributeList(shape):         print str(ce.getAttributeSource(shape, ruleAttributeName)) + ": " + \         ruleAttributeName + " = " + str(ce.getAttribute(shape, ruleAttributeName))                 if str(ce.getAttributeSource(shape, ruleAttributeName)) == "USER":             objAttributeName = os.path.split(ruleAttributeName)[1]             ruleAttributeValue = ce.getAttribute(shape, ruleAttributeName)             setObjectAttribute(object,objAttributeName,ruleAttributeValue)             ce.setAttributeSource(object, ruleAttributeName, 'OBJECT') def setObjectAttribute(object,attribute,value):     if type(value) is int:         ce.setAttribute(object, attribute, bool(value))     elif type(value) is float:         ce.setAttribute(object, attribute, value)     else:         ce.setAttribute(object, attribute, str(value)) def writeFGDB(graph,file):     exportSettings = FGDBExportGraphSettings()     exportSettings.setFilename(file)     ce.export(graph, exportSettings) if __name__ == '__main__':     # prepare export of streetnetwork     for graphSegment in ce.getObjectsFrom(ce.selection,ce.isGraphSegment):         # graphSegment to streetShape is 1:n, ':0' is street         streetShape = ce.findByOID(ce.getOID(graphSegment)+':0')         writeUserAttrToObject(streetShape,graphSegment)     # path of the output file     file = ce.toFSPath("data/Complete_Street.gdb")     writeFGDB(ce.selection(),file) ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...

Q1: Is there a way to choose multiple addresses? A1: You could add a second combo widget and set the names again: from scripting import * import org.eclipse.swt as swt import org.eclipse.swt.widgets as widgets import org.eclipse.swt.layout as layout # get a CityEngine instance ce = CE() if __name__ == '__main__':     result = None         display = widgets.Display()         shell = widgets.Shell(display)     shell.pack()     shell.open()         dialog = widgets.Shell(shell, swt.SWT.DIALOG_TRIM | swt.SWT.APPLICATION_MODAL)     dialog.setLayout(layout.RowLayout())     dialog.setText("Address Search")         names = []     OIDs = []     sceneShapes = ce.getObjectsFrom(ce.scene, ce.isShape)     for s in sceneShapes:         name = ce.getAttribute(s, 'name')         if not (name == None) | (name == ""):             names.append(name)             OIDs.append(ce.getOID(s))         searchName = widgets.Combo(dialog, swt.SWT.READ_ONLY)     searchName.setItems(names)        searchName2 = widgets.Combo(dialog, swt.SWT.READ_ONLY)     searchName2.setItems(names)     ok = widgets.Button(dialog, swt.SWT.PUSH)     ok.setText ("OK")     cancel = widgets.Button(dialog, swt.SWT.PUSH);     cancel.setText("Cancel");         class MyListener(widgets.Listener):         def handleEvent(self, event):             global result, result2             if event.widget == ok:                 result = searchName.getSelectionIndex()                 result2 = searchName2.getSelectionIndex()             else:                 result = -1             dialog.close()         listener = MyListener()     ok.addListener(swt.SWT.Selection, listener)     cancel.addListener(swt.SWT.Selection, listener)         dialog.pack()     dialog.open()     while not dialog.isDisposed():         if not display.readAndDispatch():             display.sleep ()     display.dispose()     if result>-1:         print "Selection:", names[result], names[result2]         ce.setSelection(ce.findByOID(OIDs[result]))         if result2>-1:             ce.setSelection([ce.findByOID(OIDs[result]), ce.findByOID(OIDs[result2])])         views = ce.getObjectsFrom(ce.get3DViews())         views[0].frame(ce.selection())‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ for more help on SWT widgets please visit: SWT Widgets  Q2: Is there a way to display the addresses in numerical order?

Here is an example of how to write a basic address search with GUI in Python: from scripting import * import org.eclipse.swt as swt import org.eclipse.swt.widgets as widgets import org.eclipse.swt.layout.RowLayout as layout # get a CityEngine instance ce = CE() if __name__ == '__main__': result = None display = widgets.Display() shell = widgets.Shell(display) shell.pack() shell.open() dialog = widgets.Shell(shell, swt.SWT.DIALOG_TRIM | swt.SWT.APPLICATION_MODAL) dialog.setLayout(layout()) dialog.setText("Address Search") names = [] OIDs = [] sceneShapes = ce.getObjectsFrom(ce.scene, ce.isShape) for s in sceneShapes: name = ce.getAttribute(s, 'name') if not (name == None) | (name == ""): names.append(name) OIDs.append(ce.getOID(s)) searchName = widgets.Combo(dialog, swt.SWT.READ_ONLY) searchName.setItems(names) ok = widgets.Button(dialog, swt.SWT.PUSH) ok.setText ("OK") cancel = widgets.Button(dialog, swt.SWT.PUSH); cancel.setText("Cancel"); class MyListener(widgets.Listener): def handleEvent(self, event): global result if event.widget == ok: result = searchName.getSelectionIndex() else: result = -1 dialog.close() listener = MyListener() ok.addListener(swt.SWT.Selection, listener) cancel.addListener(swt.SWT.Selection, listener) dialog.pack() dialog.open() while not dialog.isDisposed(): if not display.readAndDispatch(): display.sleep () display.dispose() if result>-1: print "Selection:", names[result] ce.setSelection(ce.findByOID(OIDs[result])) views = ce.getObjectsFrom(ce.get3DViews()) views[0].frame(ce.selection()) You can add this script as a shortcut to CityEngine ...

Thank you for the questions. For SHP files no boundaries can be defined on import. This option is only available for FileGDBs: Block/Lot Shapes can only be created within a loop in the graph network. If there is an error in the graph network (marked red), it has to be resolved first, before a block is generated. This task can be automated with the Cleanup Graph Networks tool. ... View more
