Take a look at the screenshot I posted.
Go to the admin cheat menu.
Klick on “Spawn Item”
Type “Marker” in the text field.
Choose “Building”.
Klick on the item “Marker”.
Leave the admin menu, open your character menu, drag the “marker” into your quick bar. Place it on the ground, where you want to place it. Place it. Klick on it to open menu.
From here, you are on your own. Sorry. Never used it myself and I would have to experiment the same as you.
