Autocad 2018 polyline command tutorial - how to draw polyline in autocad 2018
- 6 years ago
if you are looking for autocad polyline tutorial and polyline autocad shortcut then you came to right place because in this video, you will learn all about polyline autocad command.
A Polyline is a single object that consists of line segments and arcs. It is more versatile than a line as you can assign a width to it.
topics covered in this video are as follows:
1) polyline halfwidth setting :- Specifies the width from the center of a wide polyline line segment to one of its edges.
The starting half-width becomes the default ending half-width. The ending half-width becomes the uniform half-width for all subsequent segments until you change the half-width again. The starting and ending points of wide line segments are at the center of the line.
Typically, the intersections of adjacent wide polyline segments are beveled. No beveling is performed for nontangent arc segments or very acute angles or when a dot-dash linetype is used.
Starting half-width - Specifies the width and the start point of the segment.
Ending half-width - Specifies the width at the endpoint.
2) draw polyline arc :- The following prompts are displayed when you draw arc segments.
- Endpoint of arc
Completes an arc segment. The arc segment is tangent to the previous segment of the polyline.
- Angle
Specifies the included angle of the arc segment from the start point. Entering a positive number creates counterclockwise arc segments. Entering a negative number creates clockwise arc segments.
- Center
Specifies an arc segment based on its center point.
Note: For the Center option of the PLINE command, enter ce; for the Center object snap, enter cen or center.
Center point of arc. Specifies the center point of the polyline arc.
Endpoint of arc. Specifies the endpoint and draws the arc segment.
- Angle: Specifies the included angle of the arc segment from the start point.
- Length: Specifies the chord length (the distance from endpoint to endpoint of the arc segment. If the previous segment is an arc, the new arc segment is drawn tangent to the previous arc segment.
- Close
Draws an arc segment from the last point specified to the starting point, creating a closed polyline. At least two points must be specified to use this option.
- Direction
Specifies the tangent for the arc segment.
Tangent direction from the start point of the arc. Specifies a point that establishes a tangency of the curve to the start point. The arc curves away from the vector between the start point and the tangent point.
Endpoint of the arc. Specifies the endpoint of the arc segment.
3) draw curved lines
4) polyline thickness setting
5) Draw a Polyline with Straight Segments :- Switches from drawing arc segments to drawing straight segments.
6) basic diffrence between line and polyline
Note: A temporary plus-shaped marker displays at the first point. This marker can be useful when you create long and complicated polylines. It is removed when you complete the polyline.
The PLINEGEN system variable controls the linetype pattern display around and the smoothness of the vertices of a 2D polyline. Setting PLINEGEN to 1 generates new polylines in a continuous pattern around the vertices of the completed polyline. Setting PLINEGEN to 0 starts and ends the polyline with a dash at each vertex. PLINEGEN does not apply to polylines with tapered segments.
