Sweep error: «The path does not intersect the profile.»

[Anonymous]

Hi!

I'm new with Fusion 360 and CAD in general. I want to draw 3D structural bow. The bow is made in one piece. So I draw a sketch for the profile of my bow and at the bottom. I sweep for ~1/3 of my path selected and I have this warning and error message : 

Warning: The path does not intersect the profile. For best results, the path should intersect the profile.
Error: The path is tangent to the profile. Try adjusting the path or rotating the profile.

What it's my mistake?

Thanks,

Sketch1:

Sketch 2

I just see this solution from Autodesk, but I don't know if it's relevant to my problem.

UPDATE: I will put my file on this post.

Now, Fusion start to crash. I don't know why 😕

Sketch 2 is 3d sketch and no profile exists, 

Rail in sketch 1, are two separate paths that are not coincident at the mirror line.

Fix those and you will get a sweep to work.

Thanks @davebYYPCU,

But I don't understand by my sketch2 is not a profile. For me it's profile?

sketch1, now my mirror line is coincident with my lines. It's OK?

The top black dot in your picture means that those lines aren't constrained to each other.  zoom way in and you can see the endpoints don't touch.  I suspect this is happening in other places in your sketch also, but I haven't checked.

First thing I notice is that your sketches are not fully dimensioned?

Then I noticed that they are not fully constrained.

And perhaps more complicated than required. (see attached.

@TheCADWhisperer thanks!

How do you do that with 1 line in the sketch 2 and what is the radius of all corners? It's galvanized G60 STEEL A653, 16 GA = 1.613mm

But your dimension is not good for sketch 2 & 1. I try to reproduce a paper draw from a factory.

Can you give some documentation for your technique?

See the draw I try to reproduce : https://drive.google.com/file/d/15ASXFJrWsHoSfJLoMpI_i8BUMLUCZ04I/view?usp=sharing

Thanks in advance 🙂

1. It is often better to add Fillets as Features rather than Sketch elements. Keep thing simple.

2. You tell me.  A good bit of your work was undimensioned - so I just guessed.

3. Was this information in the original file?

4. A good bit of your work was undimensioned - but the great thing about Parametric modeling is that you can simple double click on the dimensions and change them to what they should be.

5. The Timeline is a step-by-step "cookbook" of everything I did and the order that I did it.  Learning to read the Timeline is the foundation of learning Fusion.

Thanks for this advice. And I will show my end result soon... I hope.

No collection of lines is a "profile" until it is fully closed and shaded in like this...

Another question: Why my line still blue and not black? I put many constraints? No?

no constraints

Can you File>Export and then Attach your *.f3d file here?

A common test is to simply attempt to click and drag geometry endpoints - this will usually show exactly (using logic) which geometry constraints you are missing?

But I can't help but wonder - why are you creating that closed loop for a Sweep path?  Do you have some other Design Intent in mind?
Did you see a closed path in that sketch for the example that I attached?

[TheCADWhisperer]

Why did you repeat these dimensions?

Voilà for the src file

One way to ensure fully defined geometry is to define it at each step.

Create Line 1.  Is it fully defined?  (Thumbtack on sketch.)

Yes, go to next step.

No, try dragging it - observe what is missing...

Create Line 2. Is it fully defined?

Yes, go to next step.

No, try dragging it - observe what is missing...

Step 1Step 2

Once you gain more experience and can predict the expected behavior - you can combine several steps at once.

And now, my final version :

I was very noob and now noob intermediate 🙂 , after one week of workaround. Thanks!
