7. Predefined Transformation and Selection Modes

The toolbar contains buttons for invoking different transformation and selection modes. These transformation and selection modes define the action when the left mouse button is clicked:

  • Translate: Drag the displayed NPart(s) to change their position.

  • XY-Rotate: Drag the displayed NPart(s) in x- and y-direction to rotate around the y- and the x-axis.

  • Z-Rotate: Drag the displayed NPart(s) in y-direction to rotate around the z-axis.

  • Center and Zoom in: Click on a NPart. The view is centered at the clicked location and zoomed in.

  • Center and Zoom out: Click on a NPart. The view is centered at the clicked location and zoomed out.

  • Selection: Click on a Part. A context menu appears showing the position in model coordinates and possible actions for the selected object(s). This can be used to invoke the editors for different baspl++ objects; in the above figure the NPart editor is being invoked. It can also be used to inspect the element at the position where the mouse button was clicked. Then the Model editor appears showing the element's coordinates and connectivities, as well as solution values.

  • Element Selection: Since the latter is used quite frequently, element selection mode pops up the Model editor when clicking inside an element. This is also sometimes called "picking".
