Properties Panel

The Properties panel is an affixed panel on the left side of the program interface. This panel serves different functions depending on which elements are selected or what feature is activated. When there are no features activated or elements selected, the Properties panel displays the Project Information entered for the current model. Note that hovering your mouse over the right edge of the Properties panel (as shown in the following image) allows you to drag and expand or shrink the panel horizontally.

When you select an element within the model, the Properties panel displays all of the information related to the selected element(s). You can review and modify the element information and parameters directly from the Properties panel.

When activating a feature within the program, such as adding a load or a copy/move tool, the Properties panel will serve as the method to specify and apply that feature's parameters.

You can then use the Click to Apply option to activate your parameters and click the elements you would like to apply the feature to. Or, you can click Apply to Selected in order to automatically activate and apply the feature to applicable selected elements in your model.

When navigating through a spreadsheet or inputs for a specific function, you will find a short description at the bottom of the Properties panel.

This can be very useful when you are not sure what a specific parameter means.
