Section Library
Use the automotive section library for rapid concept development in the early phases of the vehicle design process.

To access the library:
Sample Section
Each section in the section library contains:
- A Beam element with a section property
- 2D elements showing the shape of the section. The 2D element section is welded at the flanges.
- Geometric lines representing the shape of the section that can be used for concept modeling. The geometric sections are not auto-welded at the flanges.

Numbering Scheme
The section library follows a numbering scheme that is explained in detail below.
Each section can be identified by a 7-digit number
- The first digit from the left corresponds to the section’s location. It can
take values of 1, 2, or 3.
- 1: If the section is on the left side of the vehicle (for example, left-side B pillar)
- 2: If the section is on the right side of the vehicle (for example, right-side B pillar)
- 3: If the section is in the middle of the vehicle (for example, tunnel)
- The second digit from the left corresponds to the assembly of the section.
It can take values from 1 to 5.
- 1: If the section belongs to the Side Frame assembly
- 2: If the section belongs to the Roof assembly
- 3: If the section belongs to the Front Structure assembly
- 4: If the section belongs to the Front Floor assembly
- 5: If the section belongs to the Rear Floor assembly

Figure 5. Second Digit Representing Different Assemblies
- The third and fourth digits correspond to parts from the assembly. Each assembly has a number of parts; for example, the list of sample parts goes to 11 in Figure 7.
- The fifth digit corresponds to the FE representation of the section. It can
take values of 0, 2, or 5.
- 0: If the FE representation is PBEAM
- 2: If the FE representation is Beam Section
- 5: If the FE representation is PSHELL
- The sixth and seventh digits correspond to the component number.
An example of the numbering scheme implemented on the left-hand side rocker/sill section can be seen in Figure 6
