I have been trying to learn the basics of Blender and am slowly getting how it works. But for this project I am trying to make a basic room with a door one end and a fireplace in another wall.
So far, I've make a floor from a cube, then loop-cut around the edges and extruded upwards for walls. But when I want to loop cut to make the fireplace it is cutting all around the floor as well, its this the only way to do it since its all "one piece"? (pic below)
The reason I ask as this as some more important implications to how I work , just before I started this, I had to quit another one I made because I tried to make the floor and then extrude each wall one after the other. When I did this after i got to the 3rd wall the loop-cut was only cutting thru half the floor and seemed to take a strange route so I just quit and started over. (note: on the one I quit, I had been joining the edges together also using ALT-M)
Heres the pick which i think illustrates what Im trying to say ( I only want to cut the wall (but of course it needs to cut thru both front and back of the wall cube):
