How to curved a volume on X and Y ?

[Anonymous]

Hello, i've learned the basic of Fusion 360 and it looks a powerful software. Forum and tuto helped me a lot, thanks for sharing your knowledges here and there ! The path seems long for me to reach some skilled level i've seen here.

I've designed something "manually" but as i would have to repeat it, it may exist a more appropriate way to do it.

I started to drawn a rectangle volume. I draw a curved line (sketch) on X. Then an other curved line (sketch) on Y. Then i manage to "center" them with the volume, and use them to "cut" the volume.

Not sure it's that clear, so the image here represent sketch X and Y, and the volume cut. What feature would you use, or how you would proceed ?

The object will be attached to a helmet, so it needs to be "curved cut" in both direction.

If something similar has been done in the forum already, i apologies haven't seen it yet, just give me a link to it.

happy design to all !

Hi @Anonymous

One method would be to use the Sweep tool to cut or create a New Body (not sure which one would best suit your requirements). Use your profile on the left of the image you posted to sweep along your curved path perpendicular to the profile. These two Learning Fusion 360 articles will show you how to use the sweep tool.

Hope this helps.

Hi,

Could you please attach a picture of the final shape you're trying to achieve

I wanted to make a cutting board with a bowl-shaped concavity on one side. I started out doing a whole bunch of things, such as creating a sphere and intersecting it with a solid box and things like that. Then one day it occurred to me there was an easier way. Create a profile using some lines and an arc and then rotating that around the z axis. I spent hours doing it the hard way and minutes doing it the easy way.

Here is a screencast on how to make it using the loft tool

Ah yes, from your image it looked to me as if you were trying to get a non-revolved cut-out. So yes, using the revolve tool is exactly the way to go about it. Generally, there are many ways to achieve the same result in Fusion360, some are just more efficient than others.

Using the Rotate operation will give you a single curve (surface of a sphere).  The loft operation can give you compound curves.  For the OP's helmet, I think the loft operation would be best to match the helmet curves.

Forum program doesn't like "OP's", but after showing a error saying it needed correcting, it posted it anyway

Hi SaeedHamza,

the final shape is the volume you see on the picture. I did it, but it looked me a while. 

First i have to measure the curve on the helmet, in both direction (X and Y), then drawn lines, create a volume, position the lines, and try to use them to cut the volume...

not really efficient...

The curves are not the same in X and Y, as the helmet shape

I will try the loft feature and let you know.

Thank to all for sharing your experience !

I did the loft tool as with the video it looked easy, and it worked.

I haven't try the sweep tool as i was using it already (probably not the proper way) but i manage to do it with it. I also had a try mixing sweep on 2 different volumes, then intersect or combine both volume, but it takes time to align everything...and got some undesired result to adjust on final volume...

I will have a look on the tuto for the sweep tool later.

And i did not see how to use the revolve feature, so i haven't try it as well.

Thanks again for all supports,

Happy Design !
