Before trying them out, you should open an existing job (click the 
button) or create a model using the structure wizard (click the 
button).
Click on a node, member or plate to select it. Click again to deselect it. Click on a number of nodes, members or plates to select them one at a time or click once in space and then move the mouse to create a selection window (don't hold the mouse button down while moving).
Select any nodes, members or plates, click the right mouse button and then choose a tool from the menu that pops up to perform an operation on the selected items. This method is easy and lets you access 90% of the program's editing tools! It is recommended over using the menu bar or the top toolbar buttons.
Zoom in or out by rotating the mouse wheel (or hold down the mousewheel and drag), Pan by holding down the right mouse button and dragging or Rotate by holding down the left mouse button and dragging. Hit the right arrow on the keyboard to center the model and zoom to its extents. Hit the left arrow key to go back to the previous view.
Double-click on a node, member or plate to open a panel that lets you view or edit the selected item's properties. Select multiple nodes, members or plates, click the right mouse button and then choose "View/Edit Properties (Form)" from the popup menu to view or edit the properties for all the selected items.
Use the toggle buttons on the left side toolbar to turn things on or off. After turning on an analysis diagram such as a bending moment diagram for example, change load cases via the drop-down box in the middle of the top toolbar, or scroll through your load cases using the Page-Up/Down keys.
Click the large button at the top of the left side toolbar to switch between wireframe, outline or fully rendered views of your model. Wireframe mode is fastest and is useful for viewing loads and analysis diagrams, while fully rendered mode is useful for checking geometry or getting a realistic view of your model.
