In AutoCAD, the Line command works well for many drawing tasks, but the PLine command works better for others. Experience can help you choose which will work best for design needs. The PLine command draws a special kind of object — a polyline — and you might hear CAD drafters refer to a polyline as a p-line (rhymes with “bee-line,” not to be confused with the queue in a busy restroom).
The PLINE command creates an entity known as the polyline, which is basically a series of connected lines or arcs. There are some interesting tips for using polylines and the PLINE command, and many system variables that govern its use.
- Creates a 2D polyline, a single object that is composed of line and arc segments. Find The following prompts are displayed. Specify start point Sets the starting point for the polyline. A temporary plus-shaped marker displays at the first point. Pressing Enter starts a new polyline from the last endpoint specified in creating a polyline, line.

- Re: command to close polyline I run autocad 2009 only with the layers- and styles toolbars. The 'close existing polyline' command is the only command I can´t seem to type with a simple shortcut, it slows work down having to open the properties palette every time.
- POLYLINE: 2; You’ve just learned how to convert SPLINE to Polyline. It is needed to remember that the command line corresponding to Polyline is PLINE. How to convert Polyline to SPLINE in AutoCAD. It is also possible to convert a normal Polyline to a SPLINE using the PEDIT command in AutoCAD. Though this is not often needed, we will go.
Here are the primary differences between the Line and PLine commands:
The Line command draws a series of separate line segments. Even though they appear to be connected onscreen, each one is a separate object. If you move one line segment, none of the other segments you drew at the same time moves with it.
The PLine command draws a single, connected, multisegment object. A polyline is what a line appears to be; each segment is connected to form a single object. If you select any segment for editing, the changes affect the entire polyline. You can see how the same sketch drawn with the Line and the PLine commands responds when you select one of the objects. A polyline is not a pickup line used by parrots in a bar.
Use the PLine command rather than the Line command in most cases where you need to draw a series of connected line segments. If you’re drawing a series of end-to-end segments, those segments may well be logically connected.
For example, they might represent the outline of a single object or a continuous pathway. If the segments are connected logically, it makes sense to keep them connected in AutoCAD. The most obvious practical benefit of grouping segments into a polyline is that many editing operations are more efficient when you use polylines. When you select any segment in a polyline for editing, the entire polyline is selected.
Autocad Pline
Using parametrics on line segments can often produce the same results as using the PLine command.
The PLine command can draw curved segments as well as straight ones. If you want a combination of separate linear and curved segments, you must switch between the Line and ARC commands. Using the PLine command, though, you can switch between linear or circular-curve segments within a single polyline.
A polyline can have width. Polyline segment width is visually similar to the lineweight object property in AutoCAD except that polyline width can vary from segment to segment, and individual segments can be tapered. Polylines are often used for the copper conductors on electronic printed circuit boards.
Polyline Command In Autocad
Polylines can be smooth. After drawing a polyline, you can use the PEdit command to automatically reshape the polyline into a smooth, flowing curve based on the vertex points you selected.
