Hello I am new to the forum, and I have a problem with this plugin. 
It happens that just intale the plugin as instructed for SU v.8 but the toolbar disappeared, even when this option is enabled on the bar menu "view", "toolbars" .....
However, the tools are in the "plugins", "xtrusion tools" .... the only thing that is missing is the toolbar of this plugin.
I would greatly appreciate your help!
Greetings.
