IfcSverchok is packaged like a regular Blender add-on, so installation is the same as any other Blender add-on. You can download the package for installation at the Get BlenderBIM website.

Like all Blender add-ons, they can be installed using Edit > Preferences > Addons > Install > Choose Downloaded ZIP > Enable Add-on Checkbox. You can enable add-ons permanently by using Save User Settings from the Addons menu.

Before installing, you will also need to install the BlenderBIM Add-on and install Sverchok.

Nodes

List of nodes (nodes not listed here are not concidered ready for use). If you find bugs/unexpected behaviour in any of them, please open an issue or get in touch otherwise.

Node name	Inputs	Outputs	Description
IFC Create Entity	- Names - Descriptions - IfcClass - Representations - Locations - Properties	- Entities Ids	Create IFC Entity. Takes one or multiple inputs. If 'Representation(s)' is given, that determines number of output entities. Otherwise, 'Names' is used.
IFC Read Entity	- Entity Id	- Id - is_a - Other entity attributes (dynamic)	Decompose an IfcEntity into its attributes. Takes one entity id as input, returns attribute values.
IFC BMesh to IFC Repr	- Context type - Context identifier - Target View - Blender Objects	- Representations - Locations	Blender mesh to IfcShapeRepresentation. Takes one or multiple geometries. Deconstructs joined geometries and creates a separate representation for each.
IFC Sverchok to IFC Repr	- Context type - Context identifier - Target View - Vertices - Edges - Faces	- Representations	Sverchok geometry to IfcShapeRepresentation. Takes one or multiple nested lists of inputs.
IFC Create Blender Shape	- Entity Id(s)	- Blender Object(s)	Create Blender shape from IfcEntity Id. Takes one or multiple IfcEntity Ids. Creates shapes in scene and returns them in output socket.
IFC Add Spatial Element	- Names - IfcClass - Elements	- Entity Id(s)	Add IfcElements to an IfcSpatialElement. Takes one or multiple nested lists of inputs. Input can also be a (list of) spacial elements to be aggregated.
IFC Write File	- path		Writes active Ifc model to path. N.B.! It's recommended to use the 'Write File' panel under the "IfcSverchok" tab instead.
IFC Class Picker	- IfcProduct (from drop-down) - IfcClass (from drop-down)	- IfcClass	Pick an IfcClass from drop-down list.
IFC By Id	- Id	- Entities	Get IfcElement by step id. Takes one or multiple step ids.
IFC By Guid	- Guid	- Entities	Get IfcElement by guid. Takes one or multiple guids.
IFC By Type	- IfcProduct (from drop-down) - IfcClass (from drop-down) - Custom IfcClass	- Entities - Entity Ids	Get IFC element(s) in file by type. Pick an IfcProduct and an IfcClass or give a custom IfcClass.
IFC Add Pset	- Name - Properties - Element Ids	- (Pset) Entities	Add a property set and corresponding properties, in a JSON key:value format, to IfcElements.
IFC Generate Guid		- Guid	Generate a unique GUID.
IFC Get Property	- Entity Ids - Pset name - Prop name	- Value	Get the value of a property of an IfcEntity. Can take multiple entity ids.
IFC Get Attribute	- Entity Ids - Attribute Name	- Value	Get the value of an attribute of an IfcEntity. Can take multiple entities.

IfcSverchok panel

IfcSverchok creates a "IfcSverchok" tab in the Nodes panel. It includes a "Re-run all nodes" button that creates a fresh IFC File and a "Write File" button. It's recommended to re-run all nodes before saving the file either through the panel or the "Write File" node.
