Follow steps below to add deselect option within the Ribbon Menu.
To do so, type "CUI" on the command line.
Once within the CUI interface, you will need to navigate to Partial Customization Files>HYDRAWCAD>Ribbon>Panels>Setup>Row1 within the Customizations in All Files section of the window:
Once that has been located, in the bottom half of the window there should be a List of Commands. You can search for "Deselect All" within this section. Once found, you can drag this command up to the location specified above. You can see within my screenshot that I have placed "Deselect" under Options.
On the right-hand side of the screen, you can select an image to display and a "Name" that will show up in the Command Display Name. Here is an example of mine once set up:
You will then need to hit "Apply" and then "OK" and then the changes will be apparent within your ribbon menu:
The lines in the ribbon menu will change to a red color. In order to change them back, select the Options button next to the Deselect button, navigate to the application settings, then navigate to the Connection Properties tab. Select "OK" to close the window and the colors will be restored.
