MeshTools User Guide

MeshTools is a desktop mesh editor focused on inspecting polygonal meshes, building and reusing selections, and making topology-oriented edits from an interactive viewport.

Use this guide in order if you are new to the app:

1. Start with Getting Started.
2. Read Opening and Saving Files.
3. Learn the workspace in Workspace Overview.
4. Practice navigation and picking in Viewport Navigation and Selection Basics.
5. Move into reusable workflows with Entity Sets and History.
6. Use the tool pages when you are ready to edit geometry.

What MeshTools Works With

What You Can Do Today

• Import OBJ and STL meshes.
• Open and save .mt project archives.
• Orbit, pan, zoom, and reset the viewport.
• Select faces, edges, and points with click, box, toggle, and path-style selection.
• Build reusable entity sets from selections.
• Undo, redo, and jump through document history.
• Run advanced selection tools such as Expand Selection and Select Similar.
• Apply Modify Delete, Modify Create Face, and Modify Project operations.
• Change per-project up axis and customize appearance, viewport behavior, and graphics quality.

How The App Is Organized

• The left pane is the scene tree, history browser, and inspector.
• The center viewport is where you view the mesh, navigate, and select entities.
• The bottom pane shows console messages, performance stats, and the active selection breakdown.
• The Settings window holds viewport controls, import defaults, graphics options, and theme management.

Important Current Behavior

• Imported meshes are not automatically project files. Use Save or Save As to create a .mt archive.
• Project saves preserve mesh data, explicit edges, entity sets, project up axis, and console log history.
• Project saves do not preserve undo history, current selection, camera position, or app-wide settings.
• Face selection is enabled by default. Edge and point selection start disabled until you turn them on.
