Cut Paths

[swimfast831]

How could I Constrain a Line for a sweep thats sometimes a curve and sometimes a straight line?

If I understand you, it's pretty simple. 2 sketches. One for the profile you are going to sweep. And one for the path that you want to sweep the profile on. The sketch for the sweep path can consist of lines, arcs or splines in any combination. They just need to be on the same sketch. As far as "constraining" goes, both sketches should be constrained to the origin using geometric and dimensional constraints as with any good sketches.

Attached Is a profile that I want to make. I made the extrusion as a sweep.

However, I will sometimes want to make that a curved sweep. Can I do this with an arc?

Are you trying to do this pls find the attached

In a single file do you want both the configurations

can't open, i'm using inventor 08.

You can use a line, an arc, a spline or any combination of these as the sweep path.

Here is one example

if you can tie a knot.....

I don't have 2008, Sorry

What I have done ?

1) Ipart of two different paths

2) 2 sweeps and respective ones were suppressed  during creation of ipart

please see the attached images

those will explain it

Thats the way i have interpreted your "sometimes"

Please reframe your question and ask again.. which help me understand better

I read this again and realized that you might be after a single solution that could be anywhere between a line a curve.

You could have an arc segment that is so large that it is essentially a straight line for manufacuring purposes.  As the radius changes it becomes more curved. 

I have posted an example here in the past of a curve of given length.

By changing the radius the length stays the same, but the curve could vary from small radius to essentially a straight line.

exactly what I was thinking. Suppressing the other sweep is the solution.

Thanks!!!
