Schematic lines and schematic symbols are style-based content. This means the objects are defined by styles, which are sets of properties and, for schematic symbols, also include associated view blocks to represent the symbol geometry.
You can manually create the styles that define schematic lines and symbols using Style Manager.
Additionally, there are several ways to convert batches of objects to schematic symbol styles. You can
- Convert the schematic symbol styles provided with AutoCAD MEP 2025 toolset to their individual components (the settings and the view blocks), customize the components, and then convert the components back to schematic symbol styles.
- Convert a batch of AutoCAD blocks in a custom block library to schematic symbol styles.
