Geo-C-Thru earns its place in the Superhive library for putting selection-based transparency, wireframe, and viewport shading controls behind a preset system reachable straight from the viewport header.
Geo-C-Thru is a Blender add-on from VIDARIA DESIGNS Ltd. that gives real-time control over how objects appear in the viewport based on what you have selected. Objects can automatically become transparent, solid, or wireframe. You can set non-selected objects to turn semi-transparent or switch to wireframe when you select an object, or make your active selection transparent to see what's behind it. These controls are independent, so you can configure them as needed.
The preset system lets you save and load any combination of display and viewport settings, with presets available from the viewport header. Nine presets ship with the add-on, including a Blueprint preset for clean technical screenshots and X-Ray presets that separate selected from non-selected objects. You can also assign permanent display rules to a specific collection and set custom override colors, switching the Color Source between Material, Texture, or Random.
Version 2.0 added a panel to manage viewport lighting, cavity, shadows, backgrounds, and orthographic locking. The 2.1 update introduces a MatCap shading mode, a toggle to force objects solid, a raised preset limit, collapsible subpanels, and various fixes. It's built for working on specific parts of a dense model while keeping the rest of the scene visible.
Geo-C-Thru is best for blender artists working on specific parts of dense models who want to reduce viewport clutter without repeatedly hiding and unhiding geometry, plus anyone creating showcase images directly from the viewport.
Geo-C-Thru is completely free to download and use.
Geo-C-Thru includes a special ninth preset for Blender 4.5 users, described as delivering a distinct look on that version. Beyond that preset, the add-on lets you set dynamic display rules so non-selected objects turn semi-transparent or wireframe as you work, or your active selection becomes transparent to reveal what sits behind it. Controls live in the N-Panel and presets in the viewport header. For confirmation of which Blender versions are supported, check the developer's page before downloading.
Geo-C-Thru's 2.1 update adds a MatCap shading mode and a toggle that forces objects solid so everything stays visible when nothing is selected. It also raises the preset limit to fifty, makes all subpanels collapsible for a cleaner interface, and includes behind-the-scenes fixes and improvements. The update is free for everyone who already purchased the add-on. These changes build on version 2.0, which introduced direct viewport shading control over lighting, cavity, shadows, backgrounds, and orthographic locking.
Geo-C-Thru keeps its controls in one panel in Blender's N-Panel, while your favorite presets sit in the viewport header for quick switching. From there you can independently control transparency and wireframe display for selected and non-selected objects, adjust a dedicated opacity slider for the wireframe overlay, and assign custom override colors. You can also switch the Color Source between Material, Texture, or Random on the fly. Presets let you save an entire configuration and load it with a single click.
Geo-C-Thru lets you assign permanent display rules to a specific collection through its Absolute Overrides feature. For example, a collection holding all the bolts on a model can always display as wireframe, regardless of your current selection. This adds another layer of organization for complex assemblies and works alongside the dynamic rules that respond to what you select. Combined with the preset system, you can build task-specific view modes and switch between them from the viewport header.
Geo-C-Thru is listed as free in this catalog. The developer also notes that the 2.1 update is a completely free update for everyone who already purchased the add-on, so licensing terms may vary depending on where you obtain it. For current pricing and license details, check the developer's page on Superhive. That way you can confirm exactly what's included and how the add-on is distributed before you download it.
