Trim and extend
Remove part of an outline or extend an end to a boundary, with an optional overhang.
Trim and Extend are click-based editing tools. Hover over a supported outline to inspect the proposed change before clicking. Nearby eligible objects supply boundaries. The Overhang field is shared with the typed cursor input: positive values go past the boundary and negative values stop short.
Choose Trim or Extend
Choose Trim or Extend in the editing tools. The Tool Guide shows the current step and Overhang; there is no separate Apply button. An overhang of zero meets the boundary.
Preview and trim
With Trim, hover over the part to remove and check the preview, then click. Boundaries must produce a usable intersection; an empty click or unsupported outline does not make a cut. To restrict trimming to selected boundary objects, select them and hold Shift while trimming.
Preview and extend
With Extend, hover near the end to extend, inspect the preview and click. The extension needs a valid boundary in the end's direction. If it cannot reach one, use another end or change the boundary geometry.
Set a shortfall or overhang
Type a signed length in Overhang or the cursor input. For example, an explicit negative length stops short of the boundary. Use an explicit unit when the value is not in the current project units.
Continue or finish
Repeat the hover-and-click operation for further changes. Press Esc to cancel or leave the current operation. Undo reverses a committed trim or extension.
