Question: Besides joining polylines, what else does the PEDIT command in autocad applied to?
Answer take picture Q12-1 as an example. After starting the PEDIT command, the command prompt is as follows:
Among them, when you select CLOSE, you can close a polyline with a straight segment.
After selecting WIDTH, you can reset all segments of selected polylines, e.g. picture Q12-2.
When selecting FIT, you can create an arc-fit polyline and a smooth curve consisting of all vertices. The curve passes through all vertices of the polyline. E.g. picture Q12-3, at this time, the polyline consists of he tangent arcs.
Picture Q12-3(the sharp angle is the startpoint of the polyline)
When selecting spline, you can turn the selected polylines into the spline curve, using the selected vertices of the polyline as the curve control points or control frame of a curve appropriating to a B-spline. Please notice that it is still an polyline at this time. E.g. picture Q12-4.
When selecting DECURVE, you can turn all the arcs of the polylines into straight segments e.g. the picture below.
