In this part, the This section provides definitions for some key terms referred through used throughout this document are provided.
Analytical line (wall, beam, slab):
An analytical line is the representative refers to a representation of the finite element (FE) model for i) beams and ii) walls. It is mentioned as “analytical beams” and “analytical walls” in , walls, and slabs. In the AEC|BOLT AUTOCAD App, respectively.
(The prefix abbreviations “AB-” and “AW-” are used as default it is referred to as "analytical beams" for beams, "analytical walls" for walls, and "analytical slab" for slabs. The default prefix abbreviations "AB-" and "AW-" are used along with the corresponding member number: , such as AB-1, AW-3, etcand so on.)
From a mathematical point of view, two points and one line forms an analytical line. Drawing perspective, an analytical line is formed by connecting two points with a line. In the AEC|BOLT AUTOCAD App, drawing a line between two concerned points results in the generation of designated points creates an analytical line in the AEC|BOLT AUTOCAD App. In case of a discontinuity on a . If there is a break or disruption along the straight line between the two points, breakpoint(s) breakpoints should be pointed added at the locations of the discontinuity stations. A discontinuity may be due to: -change of cross-section
-interfering with another member
-offset on plan/elevation view
Figure 1a represents the formwork plan of a group . Discontinuities can occur for various reasons, including:
Change of cross-section: When there is a change in the cross-sectional properties of the member along the line, such as a transition from one shape or size to another.
Interference with another member: If the analytical line intersects or interferes with another member in the model, a breakpoint should be added to indicate the intersection point.
Offset on plan/elevation view: When there is a deliberate shift or offset in the position of the analytical line in the plan or elevation view, breakpoints should be placed at the offset stations to accurately represent the geometry.
By incorporating breakpoints at the appropriate locations, the analytical line can capture and represent these discontinuities in the structural model.
Figure 1a depicts the formwork plan for a collection of shear walls and beams. Overlaying By overlaying the architectural/structural drawing in the AEC|BOLT AUTOCAD App is , the corresponding drawing is generated. The information comes out by extracted from drawing in Figure 1a is then transformed into:

of the structure. This model provides a comprehensive representation of the building, including the shear walls and beams, in a virtual 3D environment.
Geometry for the construction documents: The drawn elements in Figure 1a, such as the shear walls and beams, are translated into precise geometric data that can be used in the preparation of construction documents. This includes generating accurate measurements, dimensions, and other relevant geometric information required for construction and documentation purposes.
By converting the formwork plan into a 3D model and extracting the necessary geometry for construction documents, the AEC|BOLT AUTOCAD App enables a seamless transition from the initial drawing to a comprehensive digital representation and documentation of the structure.

Breakpoint:
A breakpoint is defined in case of a discontinuity along a straight refers to a specific point along a straight analytical line where a discontinuity occurs. In the context of the AEC|BOLT AUTOCAD App, breakpoints are defined to handle situations where there is a change or disruption along an analytical line.
In Figure 1b illustrates , the analytical line definitions of the walls are depicted for the same given layout.
The One particular analytical line, named AW 12, represents the wall between beams B1 and B3. Along this analytical line, there is a straight line with a change in cross-section, resulting in a variation in thickness.
To accommodate this change in thickness, two breakpoints are introduced along the AW 12 analytical line named AW 12.
On the AW 12, two points represent the breakpoints due to the change of thickness.

The inclusion of breakpoints allows for precise modeling and analysis of structures, ensuring that changes in cross-section, interfering members, or offsets are accurately accounted for in the analytical line representation.

The information obtained from Figure 1c is utilized to assess the structural members' compliance with relevant building codes and design criteria. This verification process ensures that the structural elements can safely withstand the anticipated loads and meet the required standards.
By leveraging the insights gained from Figure 1c, the AEC|BOLT AUTOCAD App facilitates the creation of an accurate mathematical model and enables the verification of structural members, ultimately contributing to the overall reliability and safety of the designed structure.
