Hidden messages
When you use myCADtools, message windows sometimes appear. You can check the option to stop these messages from appearing.
The list of all the messages you've checked appears here in the " Hidden Messages " window. If you want them to reappear, simply uncheck them. You'll see the window appear again when the message needs to be visible.
This window is shared by several myCADtools tools, so you can select the tool for which you want to re-enable messages.
