Selection Plane Fill the floor

Get Help

Hello ,
I am trying to make an axonometric plan. I got the upper floors without any problems. But there was a problem while working on the basement floor. Instead of painting only the cut walls , it fills the entire floor with paint. I increased the level of the model and tried again,but it didn’t work. If you help i would be happy.

Thanks

Hi! Sorry for any inconvenient.
Could you please show me a screenshot of your issue? This may help us better understand your problem and find solution for it. :heart:
You can check if your model makes a material distinction. Also, materials with the same name will be recognised as the same material in D5.
