||Select the method used to define the axis of rotation from the drop-down list:
- Global - select a global axis and a pivot point.
- Two points - specify two arbitrary points to define a rotation axis in any direction.
|Axis of rotation
||Select a global axis used for the Global method.
||Type the arc angle from the initial copy to the final copy.
Positive angles are taken using the "right-hand rule"
(i.e., measured counter-clockwise when looking down the positive angle of rotation). Negative values may be used to rotate in the opposite direction.
||Type the number of copies to be made along the arc. These will be evenly spaced along the arc (i.e., at Arc angle / (Copies + 1) degrees along the arc).
|Helical height (optional)
||This is the distance parallel to the axis of rotation
to offset the last copy (at the end of the arc angle) from the original
selection. Intermediate copies will be offset by this distance divided by
the number of copies to form a helical arc rather than a planar arc.
||Select the structural data that you want copied to the newly generated elements:
- All — Uses all properties assigned to the selected object (e.g., loads, properties, design parameters, member releases, etc.) are copied
- Geometry Only — Only geometry data is copied. That is, nodes, member and element incidences are generated but no properties, loads, etc. will be assigned to the new objects.
- Geometry and Property Only — Only geometry data and property assignments are copied. All other assignments (e.g., loads and design parameters) are not copied.
||Instructs the program to generate new members between each step in the direction of the repeat.
||This option instructs the program to not generate linking members at the base of the structure (i.e., the lowest nodes in the selection).
||Click Select to manually identify existing nodes
or grid intersections as the axis rotation. Pick one point for the Global
method or two points for the Two point method. Alternatively, you may type
coordinates for any arbitrary points.
Type the global coordinates used to offset the rotation
axis from the origin for the Global method.
|Property ||Value |
Type the coordinates of the first and second points used to define an arbitrary axis.
|Property ||Value |
||X coordinate of the first point
||Y coordinate of the first point
||Z coordinate of the first point
||X coordinate of the second point
||Y coordinate of the second point
||Z coordinate of the second point
