+`RV_thrust_modify` allows users to make modifications to the ThrustDiagram.

-## Sub functions
+## Sub commands
 
-### VertexAttributes
+The following sub-commands are built into `RV_thrust_modify` .&#x20;
 
+### VertexAttributes
 
+The following vertex attributes of the `ThrustDiagram` can be modified.
+
+* **is\_fixed** - If set to `True`, the corresponding vertex of the `FormDiagram` will remain fixed during any force-density-based relaxation. This is set to `False` by default.
+* **is\_support** - if set to `True`, the vertex will become a support in the `ThrustDiagram` and remain fixed during `RV_tna_vertical`. This is set to `False` by default.
+* **px** - The x component of an additional load to be applied at the vertex. This value is set to 0.0 by default.
+* **py** - The y component of an additional load to be applied at the vertex. This value is set to 0.0 by default.
+* **pz** - The z component of an additional load to be applied at the vertex. This value is set to 0.0 by default.
+* **t** - The thickness of the `ThrustDiagram` at the vertex. This value in combination with the tributary area of the vertex determines the self-weight at that vertex. This value is set to 1.0 by default.
+* **x** - Current x-coordinate of the vertex. This value is automatically computed, although can be changed manually to re-locate vertices to specific positions.
+* **y** - Current y-coordinate of the vertex. This value is automatically computed, although can be changed manually to re-locate vertices to specific positions.
+* **z** - Current z-coordinate of the vertex. This value is automatically computed, although can be changed manually to re-locate vertices to specific positions.
