Dome feature?

[Anonymous]

Hi, I wonder if there's a "dome feature" similar to solidworks in Fusion 360?

Alternative, how would you suggest me to "carve out" the concave surface out of a cylinder-like body? Let's say that cilinder is created carving it out of the surface of a sphere. So the surface I'm trying to turn into concave is actually not flat. how would you do that?

Revolving doesn't really work because it's not a flat surface.

I am not sure that I fully understand what you are asking but both the dome and the concace body shown by the three pucks can be achieved by using revolve. You just need to create a sketch of 1/2 of the body cross section through the center point. Then revolve that profile about the center axis.

Thanks for the suggestion but I don't think a revolve works. I should have posted a file: http://a360.co/1UgfP2s

You can see my problem, The surface I´m trying to "reverse dome" is highlighted in blue in the screenshot and it is curved:

If your "dome" is really a sphere, and if your target is a solid, I would just use the Sphere primitive (or make your on sphere using Revolve), and position it using Move Body, then subtract using Combine.

Here is a screencast showing how to do that:

If your "dome" is not actually a sphere, you can use a Form feature to create a free-form "dome", then use Split Body to remove that part of the model.

Here is another screencast showing this workflow (I apologize for the bad modeling in Sculpt - I'm sure you can do a better job modeling the dome, but hopefully you get the idea):

Thanks jeff, I used the sphere option to accomplish it.

Hi Jeff,

Sorry to revive an old thread, but I've been trying to make a domed surface (see screenshot) just like the one you have in your screencast.  It looks like you used a sweep to create this, if yes, I'd be interested in seeing what sketch entities you used for this.  I've played around with ellipses, conics and splines as the profile and path, but I'm not getting the results I was hoping for, and the feature you have looks just what I want - can you show what you used?

Thanks,

Hi @CruftMeister

jeff didn't use any sweep in both of his videos, all he did was to create a curvature body and combine/split it from your file

Hi Saeed,

If you actually read my post you will see, I was asking about the surface geometry that he has (that I included in the screen shot) that was created before the video starts.

several ways he might have done it, but he probably lofted it like this

Laughingcreek,
 
Wow, I had no idea you could use loft like that, no wonder I wasn't getting what I wanted with sweeps - time to try some lofting - thanks so much!

I need to do the same in Fusion Inventor, unfortunately when we select the intersection point and use the move tool it automatically select the whole surface and apply the move in it, which is useless, is there a way to achieve this in Fusion Inventor? i need to make some flat surface convex and concave.

Thanks

Fusion Inventor?

Never heard of it?

Can you post screen shot of your interface?

Can you Attach the file of your Attempt here?

YEs, inventor Fusion, on OSX

here is a screenshot, as soon as i use the move tool, the whole surface selects

I am surprised that program still works - it was discontinued years ago and replaced with Fusion 360.

Well, i see, looks like i have to get fusion 360 then

So I installed Fusion 360, but i can't find the loft function anywhere, the help menu return nothing on "loft", where is this function in Fusion 360?

Edit : i got it, in the create menu, weird the help menu returned nothing
