Create ceilings from the ground floor plan by editing vertices to form quad faces, duplicate at 2600 and 2400 mm, trim with a boolean roof cutter, then join with floor.

Start by modeling the front window, duplicate to create side variations, isolate in edit mode, and form a 70 mm thick frame. Apply a boolean subtraction with the cutter.

Continue modeling the window in Blender, applying boolean and bevel modifiers to craft the inner and outer frames, glass thickness, and beveled edges with vertex groups.

Use linked duplicates to copy and place windows, combine components, and preserve modifiers like mirror and bevel; apply boolean difference to cut the window opening, align with the outline.

Learn to create a single-user window in Blender by duplicating, applying boolean modifiers, and using active-vertex snapping to align windows across ground and first floors.

Modify an existing window to a new style by duplicating it, isolating parts, deleting inner faces, merging vertices, and reapplying bevel and boolean modifiers for wall subtraction.

Enable the arc mesh add-on to create a parametric door, adjust frame width, height, thickness, and rotation, and configure opening direction for a double door.

Modify the arc mesh addon to create a double sunroom door, align the door frame, apply a boolean modifier, and adjust thickness, width, and glass sizing for a precise fit.

Create and align a side window for a sunroom door in Blender by duplicating objects, isolating the elevation, and snapping and adjusting vertices.

Model a doorway in Blender using a bevel modifier and edge bevel weight to control beveled edges. Apply scale to fix non-uniform scaling and refine the bullnose profile.

Refine a doorway in blender by applying a custom bevel to the top edges, duplicating faces, and adjusting the curve and mean bevel weight for a precise profile.

Convert the doorway profile to a mesh and fill the top and bottom sections with edges and faces. Add a bevel and enable auto smooth for a polished result.

Scale the doorway upper section from the 3D cursor as a pivot, create circular outlines with 128 vertices for smooth edges, and extrude to add glass panel thickness.

duplicate the pillar and window objects, align their center points for the doorway, and mirror the setup to the far side using the interactive mirror tool on the x axis.

Duplicate and mirror the doorway components, align the pillar and windows with the wall, then refine the opening using boolean subtraction, modifiers, and precise vertex snapping.

Finish subtracting the roof from the remaining window openings using the newly created object and a boolean modifier, then repeat the process on the back and clean up leftovers.

Troubleshoot boolean subtraction in Blender by fixing reversed normals and face orientation, then apply boolean modifiers on roof and front sections, avoiding z-fighting before uv unwrap.

Perform pre uv checks by applying boolean modifiers on roof and wall objects, remove extra geometry, reset transforms, merge duplicates, fix reversed faces, and handle multi-user windows before uv mapping.
