The Staad Analytical modeler interface need more mouse controls. For example, the model rotate options using mouse left/right bottoms, Zoom options using mouse wheel buttons etc. should be introduced in the analytical modeler. This option is already present in the 3D view and the same should be introduced in Analytical modeler also for easy modelling.
Thank you for posting this idea. It is always good to hear of different ways that users would like to operate with the controls to manipulate the model. However, I think you need to be a little more specific about what controls you think would be good to introduce. You mention the scroll wheel to zoom in the Analytical Workflow. This capability is already provided. In fact if you hold the CTRL key and scroll then this will change to be a scale modification function for any results sets such as displacement or bending moments. If you have some specific actions, then please list them in your idea.
