How do I remove objects?

How do I remove objects after building them, for example a fence that I placed without taking into account its orientation? I have right clicked on it like you would a structure but nothing happened. I have also tried Shift+Alt+Click and nothing has happened. I couldn't think of any other solutions as this is my first game.

Solution 1:

For structures you can just right click and dismantle, but for actual blocks (like fences) you need to highlight the area for dig/mining. This will require a miner with a pickaxe (regardless of what you're removing) to actually remove the material.
