| What is the Array Placement article about? | It explains the Array Placement tab in the HELIOS 3D Palette. The tab is used to create terrain, surfaces, fields, exclusion zones, requirement type areas, adjustment lines, split lines, shadow objects, and to place solar tables on the defined fields. (Helios 3D | HELP CENTER) |
| Where is Array Placement located? | It is part of the vertical menu in the HELIOS 3D Palette inside Autodesk Civil 3D. The Help Center navigation lists it under Overview of Commands > Vertical Menu > Placement > Array Placement. (Helios 3D | HELP CENTER) |
| What is the main purpose of Array Placement? | Its main purpose is to structure the placement hierarchy and define the objects required for PV table placement, including DGM terrain, surfaces, fields, exclusion zones, requirement zones, row alignment, starting points, table rows, and individual tables. (Helios 3D | HELP CENTER) |
| What is the top element in the Array Placement hierarchy? | The top element is the terrain, also called DGM. All other surface definitions are subordinate to this terrain. (Helios 3D | HELP CENTER) |
| What is located directly below the terrain in the hierarchy? | Directly below the terrain are properties or surfaces. Within these surfaces, fields can be created, and solar tables are then placed inside those fields. (Helios 3D | HELP CENTER) |
| What are fields used for? | Fields define the areas within a surface where solar tables can be placed. They are subordinate to surfaces in the placement hierarchy. (Helios 3D | HELP CENTER) |
| What objects can be defined to organize table rows within a field? | Exclusion areas, requirement type areas, alignment lines for rows, and start points can be defined to organize the arrangement of table rows within a field. (Helios 3D | HELP CENTER) |
| What is created during placement? | During placement, a collection of table rows is created. Under this collection, the individual rows are listed in order, and each row contains a numbered list of the tables placed on it. (Helios 3D | HELP CENTER) |
| What are exclusion areas used for? | Exclusion areas are used to define zones where solar tables should not be placed. The article names exclusion areas as part of the field organization structure, but the detailed rules are covered in the separate Exclusion Zones article. (Helios 3D | HELP CENTER) |
| What are requirement type areas used for? | Requirement type areas are used as additional placement-related area definitions within fields. The article mentions them as part of the field organization, but detailed behavior is described in the separate Requirement Type Zones article. (Helios 3D | HELP CENTER) |
| What are adjustment lines used for? | Adjustment lines are used to organize or align table rows within a field. The article mentions them as alignment lines for rows; detailed behavior is described in the separate Adjustment Lines article. (Helios 3D | HELP CENTER) |
| What are split lines used for? | Split lines can be created or registered from the New function and are part of the placement definition workflow. The article does not describe their detailed effect; this should be checked in the dedicated Split Lines article. (Helios 3D | HELP CENTER) |
| What does the article say about external shading? | In addition to placement options, Array Placement provides functions for calculating external shading. Shadow objects can be inserted into the drawing and their shadow projection on the terrain can be calculated. (Helios 3D | HELP CENTER) |
| What are shadow objects? | Shadow objects are objects that cast shadows on the terrain and possibly on solar tables. They are organized into a collection and attached to the drawing. (Helios 3D | HELP CENTER) |
| Which predefined shadow objects can be inserted? | The article lists predefined shadow objects such as Tree, Bush, Trunk/Pillar, Block, and House. (Helios 3D | HELP CENTER) |
| Can existing CAD objects be registered as shadow objects? | Yes. Existing objects can be registered as shadow objects through the New function or the context menu options for adding existing CAD objects. (Helios 3D | HELP CENTER) |
| How can calculated shadows be frozen or thawed? | The symbol in front of a shadow object can be used to thaw or freeze all calculated shadows with one click. If multiple layers are grouped and the status is mixed, a mixed symbol is displayed. (Helios 3D | HELP CENTER) |
What does the New button in the structure list do? | It lets users add selected polylines or lines as area definitions, draw new area definitions, create areas, fields, exclusion zones, requirement zones, adjustment lines, or split lines, register objects as shadow objects, or insert predefined shadow objects. (Helios 3D | HELP CENTER) |
| Can I create new placement objects by drawing them directly? | Yes. Areas, fields, exclusion zones, requirement zones, adjustment lines, and split lines can be drawn directly and automatically registered in HELIOS 3D. (Helios 3D | HELP CENTER) |
| Can I add existing polylines to the placement structure? | Yes. Existing CAD objects such as polylines can be added and registered in HELIOS 3D as placement-related area definitions. Lines are applicable only to start point adjustment lines. (Helios 3D | HELP CENTER) |
What does Delete Area Definition do? | It deletes an area definition from the database and asks whether the object should also be deleted from the drawing. (Helios 3D | HELP CENTER) |
| What should I check before deleting an area definition? | Check whether the definition is still needed for placement, row organization, exclusion handling, requirement handling, or shading. The command deletes the database entry and can also delete the drawing object if confirmed. (Helios 3D | HELP CENTER) |
What does Move Up do? | It moves the selected entry upward in the structure list. This can be used to reorder entries, for example the display order of fields. (Helios 3D | HELP CENTER) |
What does Move Down do? | It moves the selected entry downward in the structure list. This can be used to reorder entries, for example the display order of fields. (Helios 3D | HELP CENTER) |
| Why would I reorder entries in the placement tree? | Reordering can be used to adjust the displayed order of fields or other placement structure entries. The article explicitly mentions field display order as an example. (Helios 3D | HELP CENTER) |
What does Zoom to Object do? | It zooms into the drawing until the selected object completely fills the screen. (Helios 3D | HELP CENTER) |
When should I use Zoom to Object? | Use it when you need to locate a selected terrain, surface, field, area definition, shadow object, or other placement entry in the drawing quickly. (Helios 3D | HELP CENTER) |
What does Insert Label do? | It labels the selected entry by adding a text object with the entry name to the mouse cursor for insertion into the drawing. (Helios 3D | HELP CENTER) |
When should I use Insert Label? | Use it when a placement structure entry should be visibly named in the drawing, for example for documentation, review, or orientation in complex layouts. (Helios 3D | HELP CENTER) |
What does Select in Tree do? | When an object is selected in the drawing, it is automatically selected and marked in the structure tree. (Helios 3D | HELP CENTER) |
Why is Select in Tree useful? | It helps users find the corresponding structure-list entry for an object selected in the drawing, which is useful in large layouts with many fields, rows, areas, or shadow objects. (Helios 3D | HELP CENTER) |
| What is the Placement Tree Context Menu used for? | The context menu provides commands depending on the current selection in the structure list. The article shows that the available commands can differ, for example when a field is selected versus when a shadow object is selected. (Helios 3D | HELP CENTER) |
| Do the context menu commands always look the same? | No. The commands listed in the context menu may vary depending on the current selection. (Helios 3D | HELP CENTER) |
What do Add and Draw do in the context menu? | Their submenus are identical to the Add Area Definition button. They allow users to add existing CAD objects for registration in HELIOS 3D or draw new objects that are automatically registered. (Helios 3D | HELP CENTER) |
What does Rename do in the context menu? | It renames the selected entry in the placement structure. (Helios 3D | HELP CENTER) |
What does Delete do in the context menu? | It deletes all selected objects. (Helios 3D | HELP CENTER) |
What should I check before using Delete in the context menu? | Check whether the selected objects are still required for placement, shadow calculation, field definition, or documentation. The article states that the command deletes all selected objects, so the selection should be reviewed carefully. (Helios 3D | HELP CENTER) |
What does Apply “Project” sun date do? | It replaces the sun data of the selected fields with the settings specified on the Project page. (Helios 3D | HELP CENTER) |
When should I use Apply “Project” sun date? | Use it when selected fields should use the same sun date settings as defined on the Project page, for example to align field-specific shadow or placement assumptions with the project-wide settings. (Helios 3D | HELP CENTER) |
What does Sync. Group do? | It allows fields to be synchronized in groups so that array rows can continue seamlessly across all fields within the same group, treating them as one large field. (Helios 3D | HELP CENTER) |
| What are synchronization groups for fields? | Synchronization groups link multiple fields by assigning them a group number shown in the Sync. Group column of the placement tree. Placement commands then consistently update the layout for all fields in that group. (Helios 3D | HELP CENTER) |
| Can fields be added to an existing synchronization group later? | Yes. The article states that more fields can be added to an existing synchronization group at any time, or a new group can be created as needed. (Helios 3D | HELP CENTER) |
| Can placement options still differ between fields in a synchronization group? | Yes. Certain placement options can still be customized for individual fields, provided they do not conflict with one another. (Helios 3D | HELP CENTER) |
| What happens when placement is started for one field in a synchronization group? | When placement is initiated with a field from any synchronization group selected, the layouts of all fields within that group are updated automatically. (Helios 3D | HELP CENTER) |
| When should I use synchronization groups? | Use synchronization groups when rows should continue seamlessly across several fields and those fields should behave like one larger placement area during placement updates. (Helios 3D | HELP CENTER) |
| What should I check if synchronized fields do not update together? | Check whether the fields have the same Sync. Group number, whether placement was started from a field inside the group, and whether individual field settings conflict with the grouped placement behavior. (Helios 3D | HELP CENTER) |
What does Automated Placement do? | It automatically locates a starting point for placement of the first row. The first array is positioned at the southernmost edge of the field, and each row is placed from left to right. (Helios 3D | HELP CENTER) |
| Can the automated placement direction be reversed? | Yes. The direction can be reversed by selecting the Place Right-Aligned option in the placement settings. (Helios 3D | HELP CENTER) |
What does Reset Placement do? | It resets the placement configuration for all selected fields. (Helios 3D | HELP CENTER) |
When should I use Reset Placement? | Use it when the placement configuration of selected fields should be cleared or recalculated from a clean state. The article states that it resets the placement configuration for all selected fields. (Helios 3D | HELP CENTER) |
What does Refresh do in the placement tree? | It refreshes the structure list. (Helios 3D | HELP CENTER) |
| What should I check if newly created objects do not appear in the structure list? | Use Refresh to update the structure list. Also check whether the object was successfully registered in HELIOS 3D when it was drawn or added. (Helios 3D | HELP CENTER) |
| What should I check if an existing polyline cannot be added as an area definition? | Check whether the object type is suitable for the selected definition. The article states that selected polylines or lines can be added as area definitions, but lines are applicable only to start point adjustment lines. (Helios 3D | HELP CENTER) |
| What should I check if a selected drawing object is not marked in the structure tree? | Check whether Select in Tree is active and whether the selected drawing object is registered in the HELIOS 3D placement structure. (Helios 3D | HELP CENTER) |
| What should I check if a label is inserted in the wrong place? | The label is attached to the mouse cursor for insertion, so check the selected entry name and place the text object at the intended location in the drawing. (Helios 3D | HELP CENTER) |
| What should I check if shadow layers show a mixed status? | A mixed symbol appears when multiple grouped shadow layers do not have a clearly defined common freeze/thaw status. Use the symbol in front of the shadow object to thaw or freeze all calculated shadows consistently. (Helios 3D | HELP CENTER) |
| What should I check if automatic placement starts from the wrong side? | Check the placement settings, especially whether Place Right-Aligned is enabled. By default, automated placement starts at the southernmost edge and places rows from left to right. (Helios 3D | HELP CENTER) |
| What should I check if placement does not respect project sun settings? | Use Apply “Project” sun date for the selected fields to replace their sun data with the settings specified on the Project page. (Helios 3D | HELP CENTER) |
| What should I check if deleting an area definition leaves geometry in the drawing? | The Delete Area Definition command asks whether the drawing object should also be deleted. If the geometry remains, it may have been left in the drawing intentionally or the deletion option was not confirmed. (Helios 3D | HELP CENTER) |
| What should I check if deleting a placement entry removes more than expected? | Review the current selection before using Delete, because the context menu command deletes all selected objects. (Helios 3D | HELP CENTER) |
| How does Array Placement relate to Project and Drawing Settings? | Project and Drawing Settings define project registration, geographic location, sun date, and shadow-related values, while Array Placement uses field and placement objects where these settings can be applied, for example through Apply “Project” sun date. (Helios 3D | HELP CENTER) |
| How does Array Placement relate to the Placement Ribbon? | Array Placement provides the placement structure tree and field hierarchy, while the Placement Ribbon provides placement commands such as automated placement, reset placement, row start point tools, numbering, and snapshots. (Helios 3D | HELP CENTER) |
| How does Array Placement relate to Areas, Fields, Exclusion Zones, and Requirement Type Zones? | The Array Placement article introduces these objects as part of the placement hierarchy. Detailed behavior for each object type is handled in the corresponding separate Help Center topics. (Helios 3D | HELP CENTER) |
| How does Array Placement relate to Shadow Objects? | Array Placement includes the collection of shadow objects and supports external shading workflows by inserting or registering shadow objects and calculating their projections on terrain or tables. (Helios 3D | HELP CENTER) |
| What is the main takeaway from the Array Placement article? | Array Placement is the central vertical-menu structure for organizing PV table placement in HELIOS 3D. It defines the hierarchy from terrain to surfaces, fields, area definitions, rows, and tables, and also organizes shadow objects and synchronization groups for coordinated placement across multiple fields.
