Summary
Create a 1D member of an unstructured section using User Section.
How to Run
Ribbon Menu > [Model] Tab > [Member] Group > General > Create
Explanation
Create General Member
[Tapered Section]
Set whether to create the tapered section.[Material Type]
Set the material type of the general member.[Select User Section]
Select a user section to use.
Based on the material type setting, the corresponding user section is shown in the list.

[Assign User Section]
Place the user section on the screen.Click the Plane(3 Points) button to define the layout plane on the screen.
Click the Assign button to complete the placement.
Reference - Define Plane
[Origin Point]
Enter the coordinates of the origin to use as a reference when placing the user section on the defined plane.[Plane Axis]
Enter the two axes that will be used as reference when placing the user defined plane.Keep Section Plane : When set to On, the direction of the section is set to be same as the initial direction.
When set to On, set the section direction (the normal vector of the section) to be fixed when changing the 1D axis of the member using functions such as move Constraint Point or Edit > Move Vertex.
When set to Off, set the angle between the section direction (the normal vector of the section) and the center axis of the member to be fixed when changing the 1D axis of the member using functions such as move Constraint Point or Edit > Move Vertex.

[Generate Member]
Enter the direction and length of the general member.
Set the direction and start point of the general member.
The block that appears when the normal direction vector, selected using the Define Path method, determines the position of the geometry line section. Using the options in the drop-down menu, the geometry line of the member can be placed as shown in the illustration below.
The geometry line of the member needs to exist first for the placement of the section at the start and end points of the geometry line.
Offset (Local-Y) : Enter the offset in the Local Y axis direction from path’s starting point selected from the drop-down to translate the path horizontally.
Offset (Local-Z) : Enter the offset in the Local Z axis direction from path’s starting point selected from the drop-down to translate the path horizontally.

[Option]
When set to On, the option that appears when the Direct Draw or Select Edge method is selected sets the direction of the target section as the path’s relative direction.
When set to On, the direction of the target section is set relative to the path.
Activated when Tapered Section is selected, the tab sets the vertex matching between the start and end section of the General Member side section and its shape changes.
[Vertex Matching]
Sets vertex matching between the start and end section.[Variation Origin]
Sets the criteria by which the shape changes when Shape Variation properties are applied.[Shape Variation]
Sets the order and type of the line that connects the vertices.
Auto: This method performs Vertex Matching where the program determines one of the three methods below as necessary.
Quadrant Connection: This is a suggested method to use when the number of vertices is different between the start and end sections and creates a general member as shown below.
Connects the outermost vertex of each quadrant into a focal point of the quadrants.
Matches the remaining vertices in the order of longitudinal bisections of the start and end sections.
Match any remaining vertices to the to vertices that were matched right before to create a shape.
Quadrant Half Area : This is a suggested method to use when the number of vertices are different between the start and end sections, and creates a general member as shown below.
Connects the outermost vertex of each quadrant into a focal point of the quadrants.
Match vertices as a group for each quadrant.
Match any remaining vertices to the to vertices that were matched right before to create a shape.
Loop Sequence : This is a method to use when the number of vertices are same between the start and end sections, and creates a general member as shown below.
