In an attempt to lay carpeting down, I practiced cutting a hole in the floor, You can see the pattern on the floor where the “hole” is. My question, why is the rendering causing such zigzag striping on the floor instead of showing the whole floor covered with carpeting.
Looks like 2 floors at the same level. Concrete & carpet? Select the carpet & elevate it the thickness of the pile.
Refer to your other thread on how to select one or the other It’s description will display at the bottom of your drawing area.
