Editing the profile
Youcannotchangethelocationoftheprofileplaneaftertheprofilehasbeen
created, so it is best to determine its location when creating the path for the
sweep. This can be done by carefully planning the path because the location
of the profile plane by default is the midpoint of the first line created in the
path. Once the path has been created, the profile plane can be moved to the
start, midpoint, or end of any segment of the path as long as this is done
before the profile is sketched or selected; it cannot be changed afterward.

Swept Blends
A
swept blend
is a combination of a sweep solid and a blend solid. This tool
allows youtocreate asweepthathastwoprofiles, oneateachendofasingle
segment path. The solid geometry will transform from the shape of the first
profile to the shape of the second profile along the path.
The process for creating a swept blend is similar to that of creating a sweep,
with an extra step for defining the shape of the second profile. When you
click the Swept Blend button on the Home tab in the Family Editor, sketch
mode is activated, and you can draw or pick a path for the extrusion to
follow. When you draw a path line, the first profile location will be at the
start of the line, and a second profile location will be placed at the end of the
line.
You cannot use multiple lines to create a path for a swept blend because the
profile plane for the second profile occurs at the end of the first line drawn
