Did anyone figured out the Structure System as mentioned in the release notes:

Structure Systems

The Structure System feature is an advanced weldments environment that lets you create

and modify structural members of different profiles in one feature. The workflow is

designed to make it easier for you to create complex structure systems with flexible

corner management and trimming.

The structure system is made up of primary and secondary structural members. You build

primary members on a grid you create using 2D and 3D sketch segments, points, edges,

reference planes, and surfaces. Secondary members each run between two primary

members. You define secondary members by selecting a support plane and two primary

members, or by clicking directly on two primary members.

When you have completed defining the structural members, the software opens the Corner

Management PropertyManager so you can fine-tune the corner treatments. Corners update

automatically when you make changes to the structure system or member profiles.

These tools are available on the Structure System tab in the CommandManager:

• Create Structure System. Activates the Structure System mode. (Similar to clicking

Sketch to enter Sketch mode.)

• Primary Structural Member. Adds members defined by sketch entities, points,

reference planes, and surfaces.

• Secondary Structural Member. Adds a member between two primary members.
