Paid MAJ Interior Sketchup 2026 Plugin
Design Realistic Interior Layers with Ease
MAJ Interior brings construction-level accuracy to your SketchUp interiors. This plugin helps you build the real layers that make up interior spaces — ceilings, wall finishes, baseboards, cornices, and floors — all with precise control over dimensions and materials.
Using the clean and intuitive Dimensions Information panel, you can instantly set and adjust:
Knauf Thickness – ceiling layer thickness for true architectural depth.
Cornice Height – decorative ceiling transition for realistic interior profiles.
Wall Finish Width – interior wall finishing layer for wallpaper, paint, or paneling.
Baseboard Height – accurate floor-to-wall detail.
Floor Thickness – total buildup of the floor structure or finish.
Materials can be selected for each of the five items by viewing their individual pictures.
With just one click on Draw Interior, the plugin automatically generates every interior layer with perfect alignment and realistic proportions.
