You can edit the shape of the pipe similarly as shapes of other solids. First, the diameter of the entire pipe is changed. Next, the angle of the elbow is changed and the adjacent pipe segment is rotated to a new correct position. A point defining rotation is at the center of segment’s end circular edge. The new location of this point is at the center of the end circular edge of the changed elbow.

Selecting a pipe to change its diameters
## 4
Rotation of an adjacent segment to the correct position

A dynamic rotation of the end pipe segment is selected. As a rotation axis is used the axis of the changed elbow. As an insertion point of the rotation, a center of circle at the end is selected. Then, by moving the cursor or by detection of 3D locations, a new rotation angle can be defined. Rotation angle from initial position is displayed near the cursor.

The insertion point is moved to a new location.

Dynamic rotation is finished by left click to circular arc.
