Lumped masses and rotational inertias applied at nodes
Get List
Returns all loads with optional filtering and pagination.
Use the loadCases query parameter to filter by load cases — accepts SG list format
(e.g. "1,3-7,10"). Omit any list filter to match all.
Returns an empty array when no loads match the filter — never 404.
Results are sorted by LoadCase ascending, then by entity Id ascending.
Pagination metadata is returned in response headers (Total-Count, Offset, Limit).
query Parameters
nodesNode Ids to filter by, in SG list format (e.g. "1,5-10,12").
Returns only lumped masses applied to the specified nodes.
Omit to return lumped masses for all nodes.
loadCasesLoad cases to filter by, in SG list format (e.g. "1,3-7,10").
Returns only loads belonging to the specified load cases.
Omit to return loads for all load cases.
loadCategoryFilter by load category number. Returns only loads assigned to the specified category.
offsetNumber of items to skip from the start of the result set. Default is 0.
limitMaximum number of items to return. Default is null (return all).

resourceTypeIdentifies entity types managed by the API. Kept separate from SGFileID to allow for future API-only entities that may not have a formal SPACE GASS FileID.
countCurrent count of items in this resource. Null for sub-resources whose count does not apply uniformly.
maxIdMaximum Id currently in use (single-int Id entities only).
nextIdNext available Id (single-int Id entities only).
Field definitions describing the resource's wire shape. Each entry corresponds
to a property on the read DTO; jsonName matches the JSON key clients see.
Create Bulk
Creates multiple loads in a bulk operation. All load cases referenced must exist and be Primary load cases.
query Parameters
continueOnErrorWhether to continue processing after individual failures

Errors from failed items.
errorsTruncatedTrue when the bulk operation stopped accumulating errors after reaching SpaceGassApi.Models.Dtos.Entity.BulkResultDto`1.ErrorMessageCap. Further failures may exist beyond what is reported.
Delete Bulk
Deletes multiple lumped mass loads. Both case and node are required for each entry — providing only a case does not delete all lumped masses for that case. The succeeded array echoes back the Ids of each successfully deleted load.
query Parameters
continueOnErrorWhether to continue on error
