Path > Steel (Curve Library)

Overview of Functions

Create a steel structure that follows the path.

Path> Steel / Structure is created by extruding section or lofting different profiles. Based on the following rules, It will limit the direction of section and direction for structure generation.

- Profiles of the structure can only be created in a plane normal to the master line.

- Path of structure generation is always parallel to the master line.

These constraints are applied because they are dynamically updated based on the layout that the library are assigned. Geometry and the length needs to be automatically extended / reduced.

- EX) bridge girder

On/Off Option

Sets whether a cross section member is created.

Set whether to use the User Section.

 

Define profile plane

  • Start of target line : Defines the plane that is normal to the master line as the profile plane at the position spaced in the direction of the end point by the offset value entered from the start point of the master line.

  • End of target line : Defines the plane that is normal to the master line as the profile plane at the position spaced apart from the end point of the master line by the offset value entered.

  • User defined : Defines the plane that is normal to the master line as the profile plane at the position on the master line corresponding to the entered ratio value.

  • Distance from start profile plane* : Defines the plane that is normal to the master line as the profile plane at a distance away from the Start profile plane.

  • 3 points : You can insert General Profile through 3 point click (origin, X axis of profile, Y axis of profile) at the click of a button.

  • Direction : Sets the extraction direction of the profile.

  • Length : Enter the extraction distance of the profile.

Cardinal point

  • Cardinal point : Set the centerline position relative to the Bounding box of the profile.

  • Offset-y : Enter additional distance from the currently set cardinal point in the direction of the profile's Local-y axis.

  • Offset-z : Enter an additional distance in the direction of the Local-z axis of the profile from the currently set Cardinal point.

  • Define from view : At the click of a button, you can click anywhere on the profile plane to set the cardinal point.

Auto matching rule

  • Quadrant connection : After matching the reference, vertices of each quadrant, vertices are sequentially matched according to the Loop Sequence of the profile in the direction of 'up → down' and 'left → right'.

  • Quadrant half area : After matching the reference vertices of each quadrant, vertices are sequentially matched within each quadrant, according to the Loop Sequence of the profile.

  • Loop sequence : After matching the reference vertices of the first quadrant , match the vertices sequentially according to the Loop Sequence of the profile.
    However, if the number of vertices of start and end profiles does not match, quadrant half area method is automatically applied.

 

Rotate quadrant of end profile

  • Clockwise : Rotates the Quadrant order of the End profile clockwise.

    Counterclockwise : Rotates the quadrant order of the end profile counterclockwise.

Define shape variation

  • Variation origin : Set the reference point on the profile to determine whether the curve can be connected.

(Polynomial)

  • Curve order-y : Local Sets the degree of the curve for the y-axis direction.

  • Curve order-z : Local Sets the degree of the curve for the z-axis direction.

 

(Arc)

  • Radius-y : Local Enter the radius of the curve with respect to the y-axis direction.

  • Radius-z : Local Enter the radius of the curve with respect to the z-axis direction.

 

  • Convexity-y : Check this to apply a curve that changes convexly about the local y-axis direction.

  • Convexity-z : Check to apply a curve that changes convexly about the local z-axis direction.
