Autocad edit polyline: Mastering the Art of Editing Polylines in AutoCAD

To edit a polyline in AutoCAD, you primarily use the PEDIT (Polyline Edit) command. This powerful tool allows you to modify polylines in several ways—such as joining multiple segments, changing widths, converting lines or arcs into polylines, and smoothing corners. Here’s a step-by-step guide:

1. Select the polyline: Click on the polyline you want to edit.
2. Type PEDIT in the command line and hit Enter.
3. If prompted to select an object, select your polyline again.
4. In the PEDIT menu, choose your option:
5. Join: Combine other polylines, arcs, or lines into one polyline.
6. Edit Vertex: Move, add, or remove vertices (corners).
7. Width: Change the segment width.
8. Fit: Create smooth curves between vertices.
9. Spline: Produce a smooth spline curve through existing vertices.
10. Close/Open: Make the polyline a closed loop or keep it open.

After you make your changes, press Enter to finish editing. For multi-segment edits or advanced editing, you can also use grips by clicking on the blue squares on the polyline, which allows you to stretch, add, or remove vertices directly with your mouse.

As an interior designer, I find that efficiently editing polylines is crucial for space planning and drafting precise layouts. If you are looking for more intuitive ways to plan layouts (especially in 2D and 3D), you might be interested in exploring tools like 2D Floor Planner, which streamlines the floor plan editing process, making it more accessible and visually impactful—even for those without deep technical knowledge of AutoCAD.

Tips 1:

Always keep a backup of your drawing before major polyline edits. This ensures you can revert if needed. Leverage object snaps to maintain precision when moving or adjusting polyline vertices.

FAQ

Q: What command is used to edit polylines in AutoCAD?

A: The PEDIT command is used to edit polylines in AutoCAD.

Q: Can I convert a regular line or arc into a polyline?

A: Yes, using PEDIT, select the line or arc and AutoCAD will prompt you to convert it into a polyline before editing.

Q: How do I add a vertex to a polyline?

A: In the PEDIT menu, use the 'Edit Vertex' option to add, remove, or move vertices.

Q: How do I join two separate polylines?

A: Use the 'Join' option within PEDIT to combine multiple polylines, lines, or arcs into a single polyline.

Q: What is the difference between Fit and Spline options in PEDIT?

A: 'Fit' creates smooth curves using arcs between vertices, while 'Spline' creates a true spline curve through the vertices for a more organic look.
