Line support motion load

---

Use the Line support motion load tool to add support motion load to line supports.

When you select the Line support motion load tool from the panel, a new tool palette opens.

Main tools on the tool palette

	Description
	Use Define tool to add a new line support motion load to the model.
	Use Properties tool to check properties of existing line support motion loads. This will open the Default settings dialogue for the selected load(s).
	Use e1 numeric field to enter the value of the motion at the load's start. Only available when defining load by motion.
	Use e2 numeric field to enter the value of the motion at the load's end. Only available when defining load by motion.
	Use phi1 numeric field to enter the value of the rotation at the load's start. Only available when defining load by rotation.
	Use phi2 numeric field to enter the value of the rotation at the load's end. Only available when defining load by rotation.
or	Click on the down arrow button next to a numeric field to activate or deactivate the automatic numeric field filling function. When the function is active, program will automatically fill the next numeric field with the same value, while you enter a value in the current field. Active function's arrow background is marked with light color. Inactive function's arrow background is marked with dark color. Function is active by default.
	Use Default settings tool to change some settings (read below in more detail).

tip

Automatic numeric field filling function does not prevent you from manually entering a different value in the automatically filled field. It is just a helping function to fill in the values faster.

Motion or rotation

	Description
	Use Motion function to define a load by motion.
	Use Rotation function to define a load by rotation.

Direction tools

	Description
	Use Predefined direction function to select the load direction from 6 possible options.
	Use Parallel with line function to set the load direction by drawing a line in the model space.
	Use Perpendicular to plane tool to set the load direction to be perpendicular to a selected plane. You can select the plane in the model space.
	Use Object's local system tool to select the load direction from 3 possible options.
	Only while Predefined direction tool is selected, use this Direction tool to select one of the 6 possible options - global coordinate system X, Y or Z axis or user coordinate system x, y or z axis.
	Only while Object's local system tool is selected, use this Direction tool to select one of the 3 possible options - direction parallel to local x', y' or z' axis.
	Only while Predefined direction tool or Object's local system tool is selected, use the Positive direction and Negative direction buttons to change positive/negative direction of the selected axis or normal of the selected plane.

Line tools

Only available for the Predefined direction, Parallel with line or Perpendicular to plane directions.

	Description
	Use Straight line function to define load as a straight line.
	Use Arc by center, start point and angle function to define load as an arc by center point, start point and angle of the arc.
	Use Arc by 3 points function to define load as an arc by defining it with 3 points: start, end and middle of the arc.
	Use Arc by start, end point and tangent function to define load as an arc by its start point, endpoint and start tangent.
	Use Line by selection function to define load as a line based on any existing line or edge.

Default settings

The Default settings tool opens a new dialogue window.

	Tools and functions in the dialogue windows
e1	Change the value of the motion at the load's start. Only available when defining load by motion.
e2	Change the value of the motion at the load's end. Only available when defining load by motion.
phi1	Change the value of the rotation at the load's start. Only available when defining load by rotation.
phi2	Change the value of the rotation at the load's end. Only available when defining load by rotation.
Load case	Select a load case for the load
Comment	Add a comment to the load
	Select to apply the load so, that the direction of the load is always constant along the action line (for example, dead load or snow load).
	Select to apply the load so, that the direction of the load varies along the action line. The characteristic load direction is in the middle point of the load.
