Single Element Nudge

The Single Element Nudge tool allows the user to move or nudge a single element in a complex geometry. Can be used both on Horizontal and Vertical geometry elements.

You can access this dialog from the following:

Ribbon: OpenRail Modeling > Rail > Regression > Geometry Tools split-button.

Maintain

Civil Rules - Moves the element by maintaining existing geometry rules. This method is limited to available movement constrains for applied civil rules.

Connectivity - This method overrides any existing civil rules on the element and apply movement regardless of existing constrains. It recalculates connection to any related elements, (i.e. elements that are before/after the selected element) , and updates them where necessary to maintain connectivity.

Note: Nudge Tool overrides Point weight and Point Fixity.

Note: Maintain Connectivity option only applies to Horizontal elements.

Line

Curve

Note: If you override the radius displayed, Fix Start/End holds the points and adjusts the radius. If Fix Start/End is toggled off, it holds the center of the curve point.

Regression Specific Parameters

Horizontal

Vertical

Maximum Lift/Lower and Unacceptable Slew information input on this stage is stored on the point properties. For detailed information see Regression Point Properties.

Max Lower

Maximum lower (cut) value property of the points in the regression analysis. When this button is pressed, Nudge Offset value is updated with that maximum lower value. You can then use one of the nudge commands, such as Start and End Points > Geometry Heigh, to move up or "bump" all of the created geometry up, ending up with an element that does not have any lower (cut) sections.

After "bump".
