Move / Rotate Model Elements
The model elements move options can be found on the Modify ribbon in the Move section.

Move or Rotate Selected Items
To move
-
Open a model view if one is not already open.
-
Go to the View ribbon.
-
Click the Open 3D Views icon.
-
- Select the items you want to move by clicking on them or clicking and dragging over them.
-
To linearly move the selection:
-
Go to the Modify ribbon.
-
Under the Move section,
- Global (See Global Move for more information.)
- Local Offset(See Local Offset Move for more information.)
-
-
Click the Point to Point icon, to move the selection based upon two selected points for direction and distance.
See Point to Point Move for additional information.
-
Click the Rotate icon and specify the axis and angle, to move the selection in a polar fashion.
See Rotate Move for additional information.
-
Click the Scale button and enter a scaling factor, to scale the selection.
See the Scale Elements
- Be sure to check your member orientations after performing the copy. RISA-3D will apply the default member orientation if you do not explicitly define it. You may use a K joint to help maintain orientations. See Defining Member Orientation for more information.
- You can undo any mistakes by clicking the Undo button in the Quick Access toolbar.
Global Move
You can move the selected part of the model. Just enter the desired translation distances in the global axes directions.
Local Offset Move
You can offset elements in the model by choosing a local axes direction, specifying an increment, then clicking the element of the mode you wish to move.
Point to Point Move
You can move elements in the model by clicking on any two points. The selected items will move the distance and direction based upon the vector drawn from your first to your second points.
Rotate Move
To rotate the selected parts of the model about an axis enter an axis of rotation, the desired rotation angle, and the coordinates of the polar origin (the point rotated about). Only two of the three polar coordinate values are used, the value corresponding to the axis of rotation is ignored. Instead of specifying coordinates for a polar origin, it may instead be chosen by clicking in the model view. Select Click to Locate, specify the appropriate Rotation Axis and Rotation Angle, then click Click to Applyor Apply to Selected. The cursor will show a finger pointer, with which a polar origin may be specified by left-clicking on a node or snap point.
For example, say you wish to rotate the selected part of your model 90° about the Z-axis. You would enter "Z" as the axis of rotation and "90" as the rotation angle. Under specify origin, select Coordinates or Click to Locate. If Coordinates enter the X and Y coordinates of where you want the Z-axis of rotation to pass through the XY plane. If Click to Locate is selected, press Apply to Selected then click a location in the 3D view.
Checking the Adjust Local Axis box will cause the local axis of each member to be rotated along with the model elements. Otherwise, the member local axes will retain their original orientation with respect to the global axis. The local axes of Plates and Solids will ALWAYS be rotated along with the model elements.
Drag and Move in 3D View
You can quickly move selected elements using the drag-and-move feature. To turn this feature on or off, click the "Move Nodes Lock" button 
on the ribbon toolbar. Unlocking this will enable the drag-and-move feature.
To use this feature, select the elements you wish to move, then click and hold on a reference node (similar to a Point-to-Point move). A red line will appear in the 3D view, indicating that you are in drag-and-move mode. Next, hover over the destination node and release; the selected elements will move to the new location. If you want to move the elements in the Global X, Y, or Z directions, you can hold the Shift key while performing the drag-and-move actions.
