| What is the SLD Description article about? | It explains the HELIOS 3D functions for creating single-line diagrams from the completed electrical layout, including the SLD philosophy, symbol system, configuration options, partial SLD extracts, and helper tools for custom symbols. (Helios 3D | HELP CENTER) |
| Where is the SLD Description topic located? | It is part of the vertical menu workflow under Overview of Commands > Vertical Menu > Electric > SLD Description. (Helios 3D | HELP CENTER) |
| What is the main purpose of the SLD function? | The SLD function creates a single-line diagram from the electrical tree generated by the electrical layout. It simplifies documentation work and lets the user control the level of detail shown in the diagram. (Helios 3D | HELP CENTER) |
| What prerequisite is required before creating an SLD? | A completed electrical layout is required, because the SLD is created from the electrical tree generated by that layout. (Helios 3D | HELP CENTER) |
| Is the SLD based on international or national electrical standards? | No. The article states that the representation is not based on specific international or national standards. If standard-specific symbols are required, users can adapt the symbols themselves. (Helios 3D | HELP CENTER) |
| Which symbols are used for automatic SLD creation? | HELIOS 3D uses its own predefined SLD symbols for automatic diagram creation. (Helios 3D | HELP CENTER) |
| Can users create their own SLD symbols? | Yes. Users can extend the symbol library with their own company-specific or more complex symbols, but these custom symbols are inserted interactively by the user and not automatically by HELIOS 3D. (Helios 3D | HELP CENTER) |
| What is the HELIOS 3D SLD philosophy? | HELIOS 3D SLDs are generated directly from the electrical structure. The electrical tree acts as a preview of what the SLD function will draw, depending on which parts of the tree are expanded and visible. (Helios 3D | HELP CENTER) |
| How does the electrical tree influence the SLD output? | The SLD is drawn according to the expanded and visible parts of the electrical tree. If tree details are hidden or collapsed, the SLD is drawn with less detail. (Helios 3D | HELP CENTER) |
| What data does the SLD use? | The SLD displays information from the electrical tree and supplements it with data from the device database. (Helios 3D | HELP CENTER) |
| Can identical electrical structures be summarized in the SLD? | Yes. Identical elements can be summarized to reduce the display height. If more than three identical structures are found, they are summarized and shortened. (Helios 3D | HELP CENTER) |
| What happens if more than three identical structures are found? | HELIOS 3D summarizes them in the SLD so the diagram becomes shorter. The number of collected elements is shown behind the three vertical dots. (Helios 3D | HELP CENTER) |
| Where can I find the SLD function in HELIOS 3D? | The function is subordinate to the icon for displaying the electrical structure and is opened with the marked SLD icon shown in the article. (Helios 3D | HELP CENTER) |
