Use the Bend Part feature to bend a portion of a part.
First you define the tangency location of the bend using a 2D Sketch line. Then you can specify the side of the part to bend, the direction of the bend, and its angle, radius, or arc length.
To define the location of the bend, sketch an open profile consisting of a single line segment to serve as the bend line. The sketch plane on which that sketch is created serves as the neutral plane of the bend.
Typically, place the sketch plane on the side of the part where the bend occurs or at the center of the bend. Also, place your sketch plane at a height where you can measure the results.
The most common bend is a bend line that divides a part into two portions so that you can bend one or both portions. On a complicated part, you can use Bend Minimum, and then use the bend line to isolate and bend specific portions of it.
You can limit the length of the open profile so that it touches only the portion of the part that you want to bend. Sketch the open profile directly on the face of the portion you want to bend. Then you bend one portion of the part rather than multiple portions that can lie on the same projection direction of the open profile.
