Editing the Properties of a Polyline or
Polygon Segment
You can change the appearance of a polyline or polygon segment using
vertex editing and the edit bar. The edit bar’s width text boxes control the
thickness of the polyline segment at its beginning and end. Typically, these
values are the same, for example on a polyline representing a wall that is 4"
thick. Setting these properties to different values creates a segment with a
tapered appearance. When checked, the constrain check box forces the same
value that you enter in the Width text box to be used for both ends. This
results in a segment that is not tapered.
The Bulge Factor text box allows you to create a curved polyline segment.
The value of a bulge is equal to two times the measured height of the bulge,
divided by the distance between its startpoint and endpoint. Another way to
measure bulge is the tangent of one-quarter of its included angle. For infor-
mation on bulges, refer to “Drawing Polylines” on page 139.
To change the properties of a polyline or polygon segment
1 Enter vertex editing mode.
2 Click the segment you want to edit. The segment is highlighted.
3 Change the settings for start width, end width, bulge, or other settings on
the edit bar.
Controlling the Visibility of a Segment
Each polyline segment is either visible or hidden. AutoSketch automatically
hides the segment that a symbol occupies when using Symbol, Insert on the
Draw menu. You can also make a segment hidden, or make it visible again,
by using vertex editing. Making a segment hidden does not open a polygon
or change its other properties.
TIP The selection handles appear around the extent of the entire selected
entity, including hidden segments. When AutoSketch is in vertex editing mode
and you pass the pointer over a hidden segment a small slash appears on the
pointer. This is a useful feature for locating hidden segments.
