Weld, Unifying Edges in SketchUp with Precision

The Weld extension for SketchUp, developed by TIG, serves as a valuable tool for users who seek to unify or merge coplanar edges into a single, continuous edge. Welding is particularly useful in situations where separate edges need to be combined to create a seamless geometry, enhancing the precision and visual coherence of a SketchUp model. Let's explore the key features and the process of using the Weld extension.

Key Features of Weld Extension :

1. Edge Unification

Weld facilitates the process of merging coplanar edges, allowing users to create a single, connected edge where separate edges once existed.

2. Precision Control

The extension provides control over the welding process, ensuring that users can precisely define which edges should be welded together. This level of precision is crucial for maintaining the integrity of the model.

3. Automatic Detection

Weld can automatically detect coplanar edges, making it efficient to unify edges without manual selection. This automatic detection simplifies the workflow, especially in scenarios with numerous coplanar edges.

4. User-Friendly Interface

The extension integrates into SketchUp with a user-friendly interface, making it accessible for users of varying skill levels.

How to Use Weld Extension :

1. Installation

Download and install the Weld extension from the SketchUp Extension Warehouse or the official SketchUcation Plugin Store.

2. Activate the Tool

Once installed, activate the Weld tool within SketchUp.

3. Select Edges

Choose the coplanar edges that you want to weld together. You can either manually select the edges or let the extension automatically detect them.

4. Execute Weld

Execute the weld operation, and witness the selected coplanar edges merging into a single, continuous edge.

5. Adjust Parameters (Optional)

Depending on the complexity of the model and the desired level of precision, you may have options to adjust parameters within the Weld interface.

6. Review and Refine

Review the results and refine the model as needed. The Weld extension enhances the visual coherence of the model by creating seamless connections between coplanar edges.


The Weld extension proves to be an essential tool for SketchUp users engaged in precise modeling tasks. Whether you're working on architectural designs, product modeling, or any project that demands clean and unified geometry, Weld provides a straightforward solution. Experiment with its features, explore the automatic detection capabilities, and discover how Weld can contribute to the efficiency and precision of your SketchUp modeling endeavors.
