Creating Path Sketches
Path sketches can be both two dimensional and three dimensional. Like
open profile sketches, they can be open shapes. In this exercise, you create
only the path sketches, but not the profiles that would sweep along the
paths.
Creating 2D Path Sketches
A 2D path sketch serves as a trajectory for a swept feature. You create a swept
feature by defining a path and then a profile sketch of a cross section. Then,
you sweep the profile along the path.
The geometry for the 2D path must be created on the same plane.
Valid geometry that can be used to create a 2D path includes
■ Lines
■ Arcs
■ Polylines
■ Ellipse segments
■ 2D splines
When you solve a 2D path sketch, you can automatically create a work plane
normal to the start point of the path. You use this work plane to create a pro-
file sketch for the swept feature, and then constrain the profile sketch to the
start point of the path.
