# Merge faces The **Merge Faces** tool combines multiple adjacent faces into a single face, reducing geometry complexity while maintaining the overall shape of the model. #### How it works * Select two or more connected faces. * Activate the tool to merge them into a single face, removing unnecessary edges. {% embed url="" %} #### Use Cases * Simplifying geometry for optimization and performance improvements. * Cleaning up topology by reducing unnecessary subdivisions. * Preparing models for efficient UV mapping and texturing. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://help.vectary.com/documentation/design-process/edit-mode/merge-faces.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
