Extend Edges
A tool for extending selected edges to the nearest suitable geometry.
Supports Editable Poly, Edit Poly, and Editable Mesh, works with multiple objects at once, and retains the selection of edges and vertices. The tool can be launched from any tab in the Command Panel — it is not necessary to be in the Modify tab or on a specific sub-object level.
- Extend — extends the selected edges to the nearest intersection with the geometry of the original object.
- Extend Others — additionally uses other visible, non-hidden objects in the scene as obstacles and targets for extension.
If only one vertex of the selected edge is additionally highlighted, only the corresponding end is moved.
During the operation, active constraints of Editable Poly / Edit Poly, such as Constrain to Edge, Face, or Normal, are temporarily disabled and automatically restored after execution.
Useful for closing gaps, extending edges to adjacent geometry, and quickly aligning mesh boundaries.
