\r\n\r\n\r\n\r\nIn this tutorial a parametric railing style from a Grasshopper definition will be created.<\/p>\r\n\r\n
The 3 main steps to follow are the same as in any other Grasshopper style:<\/p>\r\n\r\n
You can download the complete Grasshopper file clicking here<\/a>.<\/p>\r\n\r\n Type They define the values of the resulting railing style. Railings require a Curve input parameter as their path curve. In this example we can find the following kind of input parameters:<\/p>\r\n They are the \u201cending\u201d components. They need to be Geometry Params<\/strong> that are no further connected to any other components. They will be read by VisualARQ as the different parts of the railing style. In this case all geometry is collected by a single Brep Param<\/strong> component.<\/p>\r\n <\/li>\r\n <\/ol>\r\n\r\n The complete Grasshopper definition is shown in the image below:<\/p>\r\n\r\n The Grasshopper definition that generates the railing.<\/p><\/div>\r\n\r\n<\/section>\r\n\r\n In this case the Grasshopper style will be created and managed from the Railing Styles Properties dialog.<\/p>\r\n\r\n Assuming the Grasshopper definition (.gh file) is already done, open the railing styles dialog: Click on the New…<\/em>\u00a0button and select the Grasshopper style<\/strong> option.<\/p>\r\n\r\n The Grasshopper Style wizard will appear. This wizard will guide you through the steps to define the railing Grasshopper style parameters. The left side of the wizard will show a preview of the object style generated as soon as the required information is completed.<\/p>\r\n\r\n Click on the Browse<\/em> button to select the .gh file created before.<\/p>\r\n\r\n Set the Railing Grasshopper style global values:<\/p>\r\n\r\n Specify which of the geometry blocks to import into VisualARQ. The identifiers of these Geometry blocks are taken from the names of the output components in the Grasshopper definition and can be modified only once the style has been created.<\/p>\r\n\r\n Each component can be assigned to a different representation:<\/p>\r\n\r\n In this case there is only one geometry output which is the Model representation, that means that the Plan representation will be taken from the horizontal section of the 3D elements according to the level’s cut plane height.<\/p>\r\n\r\n This step shows the settings available for the list of input parameters that define the railing style. In this case the possibility to \u00ab\u00a0Filter by\u00a0\u00bb is not relevant since in the Grasshopper definition there were no named groups for the input parameters. The settings are:<\/p>\r\n\r\n Name<\/strong>: is the identifier of the parameter and can be modified if desired in this step.<\/p>\r\n\r\n Editable by<\/strong>:<\/p>\r\n\r\n You can change the settings of different parameters at once by selecting them while holding the Ctrl<\/kbd> key.\r\n\r\n Default<\/strong> (value): shows the default values for the parameters, (those specified in the Grasshopper definition), including geometry entities and lets you set different ones. In this case there is one Brep parameter assigned to the baluster geometry. It is recommendable to \u00ab\u00a0internalize data\u00a0\u00bb on that component in the gh file before saving it, in order to have a solid already assigned. In case there was no internalized geometry the value field would appear as \u00ab\u00a0Unknown\u00a0\u00bb in red, indicating an unreferenced geometry and you would be requested to pick a Brep from the model to continue. (For this particular example, the solid selected must be placed in the 0,0,0 coordinates and oriented perpendicular to the XY plane, in order to be aligned properly with the railing path. This can be avoided if the gh file places the referenced solid in the (0,0,0) coordinates).<\/p>\r\n\r\n Type<\/strong>: shows the different types of values available for each kind of parameter. In this case we have a geometry parameter which is automatically set to Brep and a numerical one which has been automatically set to Length because in the Grasshopper definition it was a floating point value input.<\/p>\r\n\r\n<\/section>\r\n\r\n Once the Grasshopper style wizard is completed, the new style will appear in the railing styles list. To edit the style again, right-click on the style name to open the context menu and select Edit<\/em>. This operation will open the Grasshopper style wizard again.\r\nThe parameters are available under the tab \u00ab\u00a0Parameters\u00a0\u00bb and appear grouped as in the Grasshopper definition. In case the name of the group matches an existing category they will appear in the same category.<\/p>\r\n\r\n Once the railing style is created, you will be able to insert an instance in the document and change the values of its parameters from the Properties panel VisualARQ section, as any other regular VisualARQ object. However only those input parameters editable \u00ab\u00a0by Object\u00a0\u00bb will appear.<\/p>\r\n This railing can be also inserted using the Railing From Curves command.<\/p>\r\n\r\n Railing Grasshopper Styles Tutorial In this tutorial a parametric railing style from a Grasshopper definition will be created.

\r\nThe Grasshopper Styles are those VisualARQ object styles created from Grasshopper definitions.\r\nYou need\u00a0to have Grasshopper<\/a> installed.\r\n\r\nThe process of generating and using a Grasshopper style can be defined in 3 steps:\r\n\r\n\r\n
1. Grasshopper definition setup<\/h3>\r\nType Grasshopper<\/em> in the Rhino Command line to launch Grasshopper.\r\n\r\nIn order to use a Grasshopper definition for creating a VisualARQ object, you need:\r\n\r\n

Edit the style<\/h4>\r\nOnce the grasshopper style wizard is completed, the new style will appear in the object styles list.

Only those input parameters editable \"by Object\" will appear in the Properties panel. \r\n\r\n
