FBD Create and Edit
Use the Free-Body Create tool to create and edit free-body section entities.
A free-body section entity can be defined by selecting a group of elements which will give a contribution of forces and moments at selected interface nodes. A free-body section can also be defined by a cutting plane in space, finite or infinite, with optional limitation of contributing parts.
In each section, you can define the summation point location and the system used by the section to resolve forces and moments components. The definition of multiple free body sections can be saved in a template file (*.csv file) and can be imported in another session later.
Create a Mesh Based Section
Create a Infinite or Finite Cut Section
Edit Existing Free-Body Sections
- From the Free Body Sections browser, select and right-click a free-body section and select Edit from the context menu.
- Make and apply edits to the free-body section.
Convert Sections to Mesh Based
Realize an Infinite Cut or Finite Cut section to convert it to an explicitily defined section by elements and nodes by changing the support to Mesh.

- SectionName
- The free-body section name.
- SectionColor
- The free-body section color (Integer 0-64).
- SectionType
- Defines the type of free-body section.
- Element List/BasePoint
- Defines a list of elements ID for the Mesh type or the coordinates of a base point for other types.
- NodeList/Normal
- Defines a list of nodes for the Mesh type or the components of a plane normal vector for plane based sections.
- SumPointType
- Defines whether the resultant point for moment summation is defined by position, node, or centroid.
- SumPointValue
- Defines the actual location where moments will be summed up:
- If the summation type is at the centroid it must be left empty.
- If the summation point is at a node it must store a node ID.
- If the summation point is a position it must store coordinates.
- ResolvedInSystem/Orientation
- Defines in which coordinate system the forces and moments should be calculated.
- SystemID
- Stores a Coordinate System ID.
- PlaneBreadth
- Height of the finite section (along y-axis) centered on the base point.
- PlaneLength
- Width of the finite section (along x-axis) centered on the based point.
- IntersectType
- Entity type of the list defined in IntersectionList.
- IntersectionList
- List of entity IDs of type defined in IntersectType.
- Thickness
- Float that represents the plane thickness.
Create Free-Body Sections From File
Import a *.csv file to import free-body sections.
Following the export of free-body sections, you can import a *.csv file and create several free body sections.
