The street and intersection parameters cannot be changed through CGA rules.  You cannot change the underlying shapes, but you can create models that don't have sidewalks, for example, by making the following rule:  Sidewalk --> NIL.  But, this is probably not what you want to do since it would be harder to deal with the minArcRadius in the rules. You can change some default settings used when drawing streets by going to Graph -> Street Creation Settings.  You can set values for sidewalk widths, but unfortunately, the intersection parameters are missing, so you cannot set a value for minArcRadius.  (We hope to improve this in the future.) To set the minArcRadius, you'll have to draw all of your streets first, select them all, and then manually set the value of minArcRadius to 0 in the Inspector. Or, you can use a Python script to set the values of sidewalkWidthLeft, sidewalkWidthRight, and minArcRadius for all of the streets in your scene.  Here is some code that does this: # get graph segments and nodes segments = ce.getObjectsFrom(ce.scene, ce.isGraphSegment) nodes = ce.getObjectsFrom(ce.scene, ce.isGraphNode)     # set sidewalk widths to 0 ce.setAttribute(segments, '/ce/street/sidewalkWidthLeft', 0) ce.setAttributeSource(segments, '/ce/street/sidewalkWidthLeft', 'USER') ce.setAttribute(segments, '/ce/street/sidewalkWidthRight', 0) ce.setAttributeSource(segments, '/ce/street/sidewalkWidthRight', 'USER') # set minArcRadius to 0 ce.setAttribute(nodes, '/ce/crossing/minArcRadius', 0) ce.setAttributeSource(nodes, '/ce/crossing/minArcRadius', 'USER') ...
