Members can be created (and edited) via the form, the datasheet, or by using mouse controls. To use mouse controls, click and drag from the starting node to the ending node, and release the left click button.
To specify a member in SkyCiv Structural 3D simply provides values for:
- Node A: The node where the member starts. Specified by the node number.
- Node B: The node where the member ends. Specified by the node number.
- Section ID: The cross-section of the member identified by its ID.
- Node A Fixity: How the member is connected to the starting node A. Specified by a fixity code.
- Node B Fixity: How the member is connected to the ending node B. Specified by a fixity code.
Please visit our documentation on offsets to learn more about node and member offsets.
The Advanced Settings for members can be viewed by activating its toggle switch. Advanced form fields have blue labels, and include options for:
- Type: Members can be Normal (supporting tension and compression), Continuous, Cables, or Rigid Links.
- Angle of Rotation: The angle (in degrees) to which the member is rotated about its own axis.
- Node A Offsets: Specify a distance offset at the starting node A. Use this to model members that are not connected at the centreline.
- Node B Offsets: Specify a distance offset at the ending node B. Use this to model members that are not connected at the centreline.

Rigid Links can be useful to define rigid connections between structures that involve stacked beams or members. They are often thought of as imaginary stiff links that join members so they can translate and/or rotate together. A rigid link can also be used to manually control for member offsets. Additionally, you can change the fixity/releases in the rigid link to control what forces and effects it has on what it connects to.
