It’s important to make sure that Edge/Segment Snap has opened. If the doors and windows that you create don’t intersect with the wall automatically, you can make them intersect after linking them to each other. When you create the objects, don’t forget that in order to make them intersect automatically, the first click has to be done on the wall.
After activating the Endpoint Snap, I created the floor plane. Thanks to Endpoint Snap you will see it is easily aligned to the corners. Next I copied the floor object, then rotated it 180 degrees along the X axis and aligned it to the top part of the wall. This resulted in the ceiling (Fig.05). |
