How to trim lines in 2D CAD
Trim cuts a line, arc or circle back to the nearest point where it crosses another shape. In BenCAD you drag a path across the pieces you want to remove, and everything that path touches is cut away in one go.
Opens BenCAD with trim ready. No download, no sign-up.
How to use trim in BenCAD
- Pick TRIMTap TRIM in the toolbar, in the Edit group. The cursor changes to a crosshair.
- Drag across the pieces to removePress and drag a path over each piece you want gone. You can cross several lines in one stroke.
- Let goEach piece you crossed is cut back to the nearest crossing on either side. Pieces with no crossing are removed whole.
- Undo if neededTap undo (↩) or press Ctrl+Z to put a piece back.
Tips
- Trim works on lines, arcs, circles and ellipses. A curve (spline) that you drag across is removed whole.
- Where several shapes cross at exactly one point, BenCAD tidies up the tiny leftover pieces for you, so no stray end points are left behind.
- To lengthen a line instead, use extend. To round off a corner, use fillet.
Questions
What is the difference between trim and delete?
Delete removes a whole object. Trim removes only the part between crossings, so the rest of the line stays where it is.
Can I trim more than one line at once?
Yes. Drag one path across all the pieces you want to remove and they are trimmed together, as one undo step.
