Sweep with path vs Extrude with path

THis is something new in '04. The option to choose a path of sorts while
doing an extrusion seems just like a sweep to me. Though you cant use curves
to define the path in the extrude feature. I guess I am just trying to see
why one would use the extrude vs just doing this as a sweep?

 

I don't think you can use the "Select Contours" Feature in a Sweep feature.
Also I believe it can be used to extrude non perpendicular.

AH, now that is something i never though of, no contour select toll in a
sweep

 

So the question is : why did they add a path to extrude instead of adding
"select contours" to sweep ?
Geometrically, an extrusion definitely is a special case of a sweep.
As time goes on, I notice SW adds new features and options, but never merges
features that become equivalent...

 

As I said you can extrude Non Perpendicular

I wouldn't think of it as a sweep but rather a vector. It is totally
different than sweep because it is not sweeping but rather extruding
along a vector. The vector is defined by a line with a beginning point
and an end point, so you are limited to basically a straight path
only.

Hope this helps

Exactly. Furthermore, the path (or vector) does not need to intersect
the profile like a sweep, and the length of the extrusion is still
controlled by a value and not the length of the path (vector).
