Now plugin will select model items that has property "pdms zone" for you. Only model items that are under the manually selected model item in the hierachy are selected.įirst select /STABILIZER node from the Selection Tree and after that Select Pdms Zone from the Predefined Selections combobox. So at the plugins point of view it is same if model items are selected manually or by using these functions.īefore selecting one of the available options, please select the top model item from the Selection Tree. Predefined selections are only selecting model items in the model, they don't do anything else. Suitable predefined selection depends on native model type. With predefined selections you can automatically select model items from the different hierachy levels. If we select individually all equipment under the /EQUIP group, the plugin will create 10 individual IfcElements, but if we select only the /EQUIP group then the plugin will create only one IfcElement that contains all the equipment. IFC elements in the final IFC file are based on your selection and the plugin will create as many IFC elements as there are selected model items when the process is started, This is true both when we are selecting model items manually or using predefined selections or mappings. This gave you the basic idea how the plugin is working. The plugin is asking for the file name and creates an IFC File.Īfter finished you can browse the IFC file with your favorite IFC viewer. Please enter values for ProjectName, Organisation, SiteName and BuildingName fields and press save button in the toolbar to save them for later use.Īfter that please select one or more model items in the Selection Tree.Īnd press Export to IFC to launch the exporting process. Settings Tabpage is used for entering basic project information for the IFC file. If you downloaded a trial version from the Autodesk App Store, please download sample files here: and unzip them anywhere on your computer. Open the sample model C:\Navistools2019\Models\Pdms.nwd into the Navisworks. xBIM libraries are made available under the CDDL Open Source license.Įxport IFC without Mappings My First Export IFC Exporter is using xBIM Toolkit libraries. Then you need to create predefined selection or search sets for each different object type in the Navisworks model and tell plugin which IfcType to use when exporting them. If using this way all entites in the IFC file are represented as IfcEquipmentElement.Ģ) Another way is to use object mapping. The plugin will function in 2 different ways:ġ) Straighforward way is to select model items (selection) that you want to export from the Navisworks model and export them without mapping objects. This plugin will export both the model geometry (BREP) and the related data (Property Sets) Navisworks model items can be mapped to corresponding IFC objects and properties of those model items can be mapped to corresponding IFC propertysets. This is because of exported IFC files are ASCII files and they may become otherwise too big to handle. If the source file is big, it is better to export it in several goes. With IFC Exporter you can export any file (or part of the large file) that can be opened in Navisworks to the IFC2x3 or IFC4 format. Note that you need separate license to use this module. After successful installation the program adds IFC Exporter command to the Navisworks Navistools IFC ribbon tab.
