| The sweep along
trajectory command allows you to draw a trajectory (path) and then
draw a profile and have the extrusion of the drawn profile follow
the trajectory. This is extemely useful for drawing pipes, bike frames
and a variety of other things |
- File>New>Design
- Start a new sketch
and call it sweep traj
- Sketch the trajectory
that the sweep will follow.
- Make each curve
tangent to the strainght lines and tangent to each other.
- Select the top
line and the top arc then hit
in the constraint menu
- Select both arcs
then hit
- Select the bottom
arc and the bottom line then hit
- Ensure that the
trajectory goes thru the lateral plane. This is because you will be
drawing the profile on the lateral plane and the trajectory must intersect
with the plane that the profile is drawn on!
- Use the select
workplane tool
 and select
the workplane that is perpendicular to the plane you just drew on.
- You can also select
a workplane by right clicking on it in the object browser
- Create a new sketch
on the lateral workplane called sweep profile
- Create a profile
sketch of a hole tube (outer radius = .5", inner radius = .4")
- Sweep the profile
down the trajectory by hitting
- Choose sweep
profile as the profile and sweep traj as the path, then click
ok to complete the sweep
