What happens if the Drawing Description shows Unknown? | If the Drawing Description shows Unknown, the drawing is not correctly registered in the database, so no HELIOS functions will be available. (Helios 3D | HELP CENTER) |
| What should I check if HELIOS functions are not available in a drawing? | Check whether the Project Number, Project Name, Drawing Number, or Drawing Description shows Unknown. If one of these values is unknown, the drawing is probably not correctly registered in the HELIOS 3D database. (Helios 3D | HELP CENTER) |
What is Set Latitude used for? | Set Latitude stores the latitude of the project location. This value is used to calculate the sun’s position and therefore the resulting shadows. (Helios 3D | HELP CENTER) |
What is Set Longitude used for? | Set Longitude stores the longitude of the project location. This value is used to calculate the sun’s position and therefore the resulting shadows. (Helios 3D | HELP CENTER) |
| Are HELIOS 3D geographic location settings the same as Civil 3D coordinate system settings? | No. The article states that the geographic location used for sun and shadow calculation is completely independent from the sun and coordinate system settings inside Civil 3D. (Helios 3D | HELP CENTER) |
What does Change Geographic Location do? | It opens a dialog for changing the geo position. The dialog supports GPS or UTM data, can read location data from KML/KMZ files, and can also use AutoCAD geo location settings. (Helios 3D | HELP CENTER) |
| What is the geographic position used for in HELIOS 3D? | The geographic position is used exclusively for calculating sun angles and the resulting shadow. It is independent from DWG georeferencing, which must be managed separately by the user. (Helios 3D | HELP CENTER) |
What is the Search Location field used for? | Search Location lets the user type an address and receive a list of possible locations from a web service. When a listed location is selected, GPS coordinates are read and the AutoCAD background map is displayed zoomed to that location. (Helios 3D | HELP CENTER) |
What does Zoom to location do? | Zoom to location zooms back to the selected location if the user has moved around inside the drawing. (Helios 3D | HELP CENTER) |
| Which coordinate system is used for the displayed background map? | The article states that the map uses the UTM84 coordinate system. (Helios 3D | HELP CENTER) |
| Can HELIOS 3D retrieve a surface from the web? | Yes. In the DTM / Surface section, users can optionally retrieve a free surface in UTM84 coordinates. The article describes this as a compromise solution if no better survey data is available. (Helios 3D | HELP CENTER) |
| Which external service is used to retrieve free surface data? | The article states that free surface data can be retrieved from gpxz.io. The resulting surface uses UTM84 coordinates and automatically chooses the proper zone. (Helios 3D | HELP CENTER) |
| Should the web-based surface replace accurate survey data? | No. The article describes the web-based surface as a compromise solution when no better survey data is available. For final engineering or construction-quality terrain work, accurate survey data should be preferred. (Helios 3D | HELP CENTER) |
What does Map style define? | Map style sets the map style for the AutoCAD Map service used in the drawing. (Helios 3D | HELP CENTER) |
What does Surface display style define? | Surface display style sets the style used to display the generated surface after insertion. (Helios 3D | HELP CENTER) |
| How is the rectangular surface import started? | After the creation mode starts, AutoCAD command-line prompts guide the user. The user picks the first corner of the area and then follows the next prompt to define the rectangular surface area. (Helios 3D | HELP CENTER) |
| What is the maximum size of the imported rectangular TIN surface? | The resulting rectangular TIN surface has a maximum size of 10 km². It is immediately ready to be used for creating a layout. (Helios 3D | HELP CENTER) |
What is Absolute Altitude used for? | Absolute Altitude stores the height value for the absolute altitude. This value is used in yield assessment and significantly affects temperature influences. (Helios 3D | HELP CENTER) |
| Why is the time zone setting important? | The time zone is used for calculating the sun’s azimuth and altitude based on the specified date and time. Incorrect time-zone settings make all shadow calculations inaccurate, and the article states that local standard time should always be used. (Helios 3D | HELP CENTER) |
What is Enter Date / Time used for? | Enter Date / Time defines the reference date and time for shadow calculation. All relevant fields are initialized with this value to ensure shadow-free placement. (Helios 3D | HELP CENTER) |
| Which algorithm is used for sun position calculation? | Sun azimuth and altitude calculations based on date, time, latitude, and longitude follow the algorithm defined by DIN 5034. (Helios 3D | HELP CENTER) |
What does the date/time button do? | The date/time button sets the date and time to the default sun settings. The standard reference date is December 21 at 12:00 PM for the northern hemisphere and June 21 at 12:00 PM for the southern hemisphere. These dates are not recommendations for every geographic position. (Helios 3D | HELP CENTER) |
What is Azimuth (°) of the Sun? | It is the sun azimuth in degrees resulting from the current Date / Time, Latitude, and Longitude settings. The sun position is calculated according to DIN 5034, ranges from 0 to 360 degrees, and is measured clockwise from north. (Helios 3D | HELP CENTER) |
What does Overwrite sun azimuth do? | It allows the user to overwrite the sun azimuth calculated according to DIN 5034. (Helios 3D | HELP CENTER) |
What is Altitude (°) of the Sun? | It is the sun altitude in degrees calculated for the drawing from the current Date / Time, Latitude, and Longitude settings. (Helios 3D | HELP CENTER) |
What does Overwrite sun altitude do? | It allows the user to overwrite the sun altitude calculated according to DIN 5034. (Helios 3D | HELP CENTER) |
| When should I overwrite sun azimuth or sun altitude? | Use manual overwrite only when a specific sun position must be tested or documented and the user intentionally wants to override the DIN 5034 calculation. The article states that overwrite options exist, but it does not provide detailed use cases, so this should be applied carefully. (Helios 3D | HELP CENTER) |
| What is the Display Settings section used for? | The Display Settings section controls how future table placement executions are displayed. The article states that all display options, except the complexity of array blocks, are applied to future table placement executions. (Helios 3D | HELP CENTER) |
What does Complexity of Array blocks control? | It selects the level of detail for blocks in any table insertion and updates all blocks accordingly. Reducing block details improves performance without affecting functionality. (Helios 3D | HELP CENTER) |
| When should I reduce the complexity of array blocks? | Reduce array block complexity when working with large or performance-sensitive drawings. Lower block detail can improve performance without changing HELIOS 3D functionality. (Helios 3D | HELP CENTER) |
| What do the checkboxes and radio buttons in Display Settings control? | They determine which labels are added during the placement process. (Helios 3D | HELP CENTER) |
| Do Display Settings affect already placed tables? | According to the article, all display options except the complexity of array blocks are applied to future table placement executions. Therefore, most display settings affect future placements rather than already placed tables. (Helios 3D | HELP CENTER) |
| What should I check if shadow calculations look wrong? | Check latitude, longitude, geographic location, time zone, reference date and time, and whether sun azimuth or altitude was manually overwritten. The article explicitly states that incorrect time-zone settings make all shadow calculations inaccurate. (Helios 3D | HELP CENTER) |
| What should I check if the shadow direction does not match the expected site location? | Verify the GPS or UTM coordinates, the selected location from the search field, the time zone, date and time, and any manual overrides of sun azimuth or altitude. Also remember that the HELIOS 3D sun calculation location is independent from Civil 3D georeferencing. (Helios 3D | HELP CENTER) |
| What should I check if the background map or searched location is not shown correctly? | Check whether the selected address produced valid GPS coordinates, whether the drawing can display the AutoCAD background map, and whether the location was selected from the web-service result list. The article states that selecting a listed location displays the AutoCAD background map and zooms to the location. (Helios 3D | HELP CENTER) |
| What should I check if retrieving a web surface does not work? | Check whether the selected area is valid, whether the maximum size of 10 km² is not exceeded, and whether the web surface service is reachable. The article states that the surface is retrieved from gpxz.io and uses UTM84 coordinates. (Helios 3D | HELP CENTER) |
| What should I check if the generated surface is not suitable for final planning? | Verify whether accurate survey data is available. The article describes the web-retrieved surface as a compromise solution when no better survey data is available, so it should be treated as preliminary terrain data. (Helios 3D | HELP CENTER) |
| What should I check if yield assessment results seem unrealistic? | Check the Absolute Altitude value, because the article states that it is used in yield assessment and significantly affects temperature influences. Also check project location, time-zone, and sun settings if the yield workflow depends on shadow or sun data. (Helios 3D | HELP CENTER) |
| What should I check if array block display slows down the drawing? | Reduce the Complexity of Array blocks. The article states that reducing block details improves performance without affecting functionality. (Helios 3D | HELP CENTER) |
| What should I check if placement labels are missing or not as expected? | Check the checkboxes and radio buttons in the Display Settings section, because these options determine which labels are added during the placement process. (Helios 3D | HELP CENTER) |
| How does Project and Drawing Settings relate to Array Placement? | Array placement depends on correct project registration, geographic location, date, time, sun position, shadow calculation settings, and display options. The settings defined here influence shadow-free placement and future table placement display behavior. (Helios 3D | HELP CENTER) |
| How does Project and Drawing Settings relate to yield assessment? | Absolute Altitude is used in yield assessment and significantly affects temperature influences. Location and sun-related settings may also influence shadow-related planning assumptions. (Helios 3D | HELP CENTER) |
| How does Project and Drawing Settings relate to terrain preparation? | The article includes a DTM / Surface section where a free UTM84 surface can be retrieved from the web as a preliminary terrain basis if no better survey data is available. (Helios 3D | HELP CENTER) |
| What is the main takeaway from the Project and Drawing Settings article? | Project and Drawing Settings define critical drawing registration, location, sun, shadow, surface, yield-altitude, and display parameters. If registration fields show Unknown, HELIOS functions will not be available; if location, time zone, or date/time are wrong, shadow calculations will be inaccurate. (Helios 3D | HELP CENTER) |
