On beam
On edge
On subregion edge
On opening edge
On rib
| yes | Specifies on which type of object the force acts | | Distribution | Enum |Uniform
Trapez
| yes | The load may be either constant along the 1D member or linearly variable (trapezoidal). | | Direction | Enum |X
Y
Z
Vector
| yes |Specifies the base direction of the load
X, Y, Z - action will be applied in one of these directions
Vector - size and direction calculated from vector
| | Value 1 \[kN/m] | Double | -150 | yes, if Direction = X,Y or Z |Specifies the first size of the load in, acts in one direction
Value1 is always closer to origin (see notes)
yes, if Direction = X,Y or Z
yes, if Distribution = Trapez
|Specifies the second size of the load in, acts in one direction
Value2 is always further from origin (see notes)
| | Vector 1(X;Y;Z) \[kN/m] | String | (10;10;0) | yes, if Direction = Vector |Specifies the first size of the load in, direction by vector
Note: Vector1 and Vector2 needs to be in same direction
| | Vector 2(X;Y;Z) \[kN/m] | String | (20;20;0) |yes, if Direction = Vector
yes, if Dsitribution = Trapez
|Specifies the second size of the load in, direction by vector
Note: Vector1 and Vector2 needs to be in same direction
| | Member | String | B11 | yes, if Force action = On beam | The name of the [StructuralCurveMember](https://saf.guide/Content/A_Objects/7_StructuralCurveMember.htm) on which the load is applied | | Member Rib | String | B11 | yes, if Force action = On rib | The name of the [StructuralCurveMemberRib](https://saf.guide/Content/A_Objects/25_StructuralCurveMemberRib.htm) on which the load is applied | | 2D Member | String | S1 | yes, if Force action = On edge |The name of the StructuralSurfaceMember which the load is applied.
StructuralCurveAction can act either on a 2D member edge or on internal edge.
Global
Local
| yes |Defines the co-ordinate system of the member in which the load is applied
For " Local", coordinate system is defined by the member where is load applied
| | Location | Enum |Length
Projection
| yes | Specifies whether the load is "put directly on an inclined 1D member" or whether the "projection on plan" is defined. | | Coordinate definition | Enum |Absolute
Relative
| yes | Selects the coordinate system that is used to define the length of the line load. Relative means without units. To define length of the load in meters input absolute | | Origin | Enum |From start
From end
| yes | Specifies the origin of the coordinate system used for the definition of the length of the force | | Extent | Enum |Full
Span
| yes | Defines if a load is extended just over a span instead of the whole 1D member, it is used if a 1D member consists of more than one span. This feature is not fully supported, only two spans are supported in the moment. | | Start point \[m] | Double |value in meters for Coordinate definition = Absolute
0,0
value in percentage for Coordinate definition = Relative
0,0
| yes | Defines the position of the start point of the force in relative or absolute coordinates \[m] | | End point \[m] | Double |value in meters for Coordinate definition = Absolute
5,25
value in percentage for Coordinate definition = Relative
1,0
| yes | Defines the position of the end point of the force in relative or absolute coordinates \[m] | | Eccentricity ey \[mm] | Double | -150 | yes | Eccentricity of the force system line in Y direction of the local coordinate system | | Eccentricity ez \[mm] | Double | 75 | yes | Eccentricity of the force system line in Z direction of the local coordinate system | | Parent ID | String | 67b35d84-3d04-47aa-aa4a-dc1263982320 | no |Is filled for objects created be dividing curved geometry to series of straight line objects.
Parent ID will ensure that curved edge is imported as straight parts to nonsupporting application, and back to original supporting application as curved geometry.
To ensure successful round trip of segmented objects and their related objects, Parent ID needs to be present in both directions.
| | Id | String | 39f238a5-01d0-45cf-a2eb-958170fd4f39 | no | Unique attribute designation | ## Notes {% hint style="info" %} Difference between Location type Length and Projection can be seen in the picture. Location is used only if Coordinate system is Global. {% endhint %}  {% hint style="info" %} An example of use of parameter Extent is in the in the picture below. In case of Span the load acts only on the span which is defined by internal nodes {% endhint %}  {% hint style="info" %} An example with Distribution type Trapez and with different values 1 and 2 can be seen in the following picture. Coordinate definition is relative, start point 0 and end point 0,3. StructuralCurveAction 1 has origin "From start" and StructuralCurveAction 2 has origin "From end". In this case the parameter extent doesn’t make any difference, only in case of beams consisting of more parts. {% endhint %}  --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
