Now go to ‘Vertex' mode in the ‘Editable Mesh' submenu and pick the vertices shown.


Then click on "Weld” in the ‘edit geometry' submenu. Make sure that you have 0.1m on the field next to the "Selected” button. If you have a higher value, the vertices will not weld correctly. If the value is smaller the vertices might not weld at all. This value corresponds to the minimum distance needed between two or more vertices, in order to be welded. Example: If you select 2 vertices that have 1 meter between them, you should also have "1m” in the field next to the "Selected”button, in order for them to be welded.

Continue welding each door and window opening until you reach something like the picture.

Tip: To avoid selecting or welding unwanted vertices or faces, check the "Ignore backfacing” box that's right below the "Selection” submenu.



Now let's make the floor by selecting "Box” from the "Create” menu. Select the top view and make your box object.
