Need help to round middle section of my project.

[sean_gross1229]

I am looking for help on how to round the middle section of my project. The ends I used the "revolve" function. But the revolve function does not give me the shape I want in the middle. I am looking to have the middle section match the rounded shape of the ends if that makes sense.

Revolve that entire profile and just constrain it to 180*

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

[sean_gross1229]

I will attach it when I get home.

[sean_gross1229]

I have attached the file you have requested.

[sean_gross1229]

I attached my file as I still cannot get it to revolve. I keep getting the "it crosses the axis" error. If you could take a look and let me know what I have done wrong to not allow it to revolve in the middle that would be great.

Why did you use a Spline rather than a 3-Point arc?  (There is only about the thickness of a sheet of paper difference at the greatest difference.)

[sean_gross1229]

The three point arc did not seem to give me the curve I was looking for. I may have not done it right. I have only been using fusion for about a week.

I'm not sure if this is the result you were looking for, but the key is that you need to revolve only 1/2 the profile, so you need another line in your sketch:

[sean_gross1229]

I tried adding a line going from the top of the one arc all the way to the top of the other arc and when I try to revolve it still selects the entire project. I cannot seem to select either half by itself.

Keep your sketches simple (in fact I could simplify this more).

And fully define your sketches...

[jhackney1972]

Take a look at the timeline on this model.  You need to constrain your sketch a bit more.

[sean_gross1229]

I got it. I started a new project and added a centerline and that worked. I guess it did not like me adding a centerline to the existing sketch I had before. Thanks for the help.
