Remove unuse edges faces with Ifixlt 101 plugin Sketchup

Ifixlt 101 Plugin Sketchup (its real name is FixIt 101, by Anton Synytsia) is a simple and effective plugin for correcting errors of a sketchup model, automatically removing unuse edges and faces in sketchup. Unlike the Cleanup plugin that deletes unused objects, FixIt 101 deletes the edges and inner faces inside groups or components and tries to turn them into clean solids. Understandably this is a complete editing plugin for the faces, edges and points of models.

Main Feature:

• Remove duplicate, overlapping and internal faces.
• Merge coplanar faces.
• Remove single (stray) edges and repair split edges.
• Add missing faces so a group can become a watertight solid.

Using:

• With just 1 click, the plugin automatically removes the unnecessary geometry of the models.
• If the object is selected, the plugin only works with the selected object. If nothing is selected, the plugin runs for the entire file. Always select first: run on an empty selection and it processes everything at once — on detailed scenes this is slow and can silently delete intended single faces such as window glass, which is by far the most common complaint about this plugin.

Note (still works in 2026):

FixIt 101 is a legacy plugin — the last release is version 1.5.0 (2014) and it predates the Extension Warehouse. Because it is a single pure-Ruby script with no compiled binaries, it still loads fine in current SketchUp (2024 / 2025); just install the .rbz through Extensions > Extension Manager rather than looking for it in the Warehouse. If you want an actively maintained option, Thomas Thomassen’s CleanUp³ and Solid Inspector² (both free on the Extension Warehouse) cover the same coplanar-merge / duplicate-face / stray-edge cleanup, and Solid Inspector² also highlights exactly which holes or internal faces break a solid before you delete anything — a safer workflow than FixIt’s one-click sweep.
