You can mirror structure nodes or elements horizontally, using either method:
- Click Edit menu > Edit > Horizontal Mirror.
- Click
.
To define the horizontal mirroring operation with respect to the horizontal plane, set the main parameters in the following fields of the Horizontal Mirror dialog:
- Nodes - Defines the node numbering increment when defining new nodes.
- Elements - Defines the element numbering increment when defining new elements.
- Move - When selected, the selected nodes or elements are moved in the structure (origin nodes or elements change their location in the structure).
- Copy - When selected, new nodes or elements are created in a structure (origin nodes or elements remain the same).
- Drag - When selected, additional elements are created between the existing nodes and the nodes created during editing. The elements are numbered automatically.
Also, define the coordinate value of the horizontal mirror plane in the Plane location field.
After you have graphically defined a coordinate of the plane, Robot mirrors horizontally the selected nodes or elements; or if no objects have been selected, click Select in the context menu to select them. Robot remains in horizontal mirror mode until the next command is selected or the <Esc> key is pressed.
Note: You cannot perform the horizontal mirroring operation on structure elements or nodes until you select them. You can perform the horizontal mirroring operation with respect to a plane only if the work plane (XY, YZ, XZ, LOCAL) has been selected.
