I'd like to introduce DWG to 3D, a SketchUp extension that converts 2D DWG/DXF floor plans into a clean, editable native SketchUp 3D model in one click.

What it builds

• Walls and columns: each one a separate solid group, made with face + push/pull, like you drew it by hand
• Doors and windows as components (frame + leaf/glass). Openings of the same size share one definition, so edit one and all update, or swap them with Replace Selected
• Window sills and door/window lintels
• The original 2D plan kept underneath, on its own tag
• Everything is organised on tags: Walls, Columns, Doors, Windows, Sills, Lintels, 2D Plan

Smart parts

• Detects layer types automatically (wall / column / door / window), and you can correct them in a table
• Auto scale fix: if the file's units are wrong or missing, it picks the right scale (shows the result as building size, e.g. "12.00 m × 9.00 m")
• Closes open wall ends and splits walls at windows drawn on top of them
• Tells doors from windows even when both are on one shared layer
• Settings for wall height, sill/head heights and gap tolerance
• The whole conversion is one Undo step
• Works fully offline inside SketchUp. No AutoCAD needed
• English & Turkish interface

Requirements

• SketchUp Pro (DWG/DXF import is a Pro feature)
• Tested on SketchUp 2021 (Windows). Feedback on other versions and Mac is very welcome

Known limits: hatched walls and single-line (axis) walls aren't supported yet; multi-storey drawings aren't split.

Price: $39 / year — 1-week free trial

• All updates included; one license works on 2 computers
• Cancel any time: the plugin keeps working until the end of your paid year
• Activation needs an internet connection once; after that it also works offline (up to 14 days at a time)
