How to create a surface intersection?

[thburn]

Hello,

I want to create an intersection surface of two single surfaces. But it seems that F360 doesn't provide this feature?

See the image. There I have a simple cube and two adjacent surfaces extruded from a spline curve.
Now I want to create an intersction curve out of these two curves something like a boolean intersection.

The resulting surface I want to use then to split the cube body.

I need something like boolean for the surface, hope it is clear what I want.

How can I do that in F360?

Thanks!

Not sure if this will work but from the create menu try Boundary Fill. If that doesn't work Split body on the modify menu might, you'd need to split the body twice because you can only use one split tool at a time

If you just want the intersection curves, on the Sketch menu look under project for Intersection Curve.

Hi HughesTooling,

thanks for reply but none of your proposals does work. I tested already before creating my post.

Boundary fill does not work because it needs surfaces which are complete inside the cube, but my surfaces are larger than the cube and cut the cube.

If I use the split tool twice then the cube body gets splitted completely from one side to the other side this for both surfaces as you can see here:

But this is not what I want. First I need a resulting surface from intersecting the two surfaces. And this resulting surface (only) should split my cube.

Still need help, thanks!

Hi HughesTooling,

'Intersection curve' creates a resulting curve (not surface!!!), so this also does not help.

Don't get me wrong I really appreciate your help but may you try yourself before you post here?

Thanks...

Upload the file it will be a lot easier than guessing. You could try going to the patch workspace and trimming the 2 surfaces then using the trimmed surfaces to cut the cube.

This is roughly what I want to get (done using Blender):

I don't know Blender at all, but I'm having a hard time figuring out how Blender could have gotten that result from the inputs you show in the Fusion case.  It looks to me more like you define some kind of a loft surface to cut the body.

This is one way I would approach this in Fusion:  create a loft surface, and use that to split the body.

Here is a screencast of how I would do that:

The other approach is to use a Sculpt (Form) feature to do the same thing.  It's more fiddly, but also more flexible:

Hope one of these work for you.

You cannot get that result in Blender using these surfaces as an input. In fact you cannot just do that in any software that does not read your mind 😉

I could suggest a couple of things, however, in order for that to really make sense it would really be helpful to understand what the end goal is. What is the object you are trying to design and is this purely a modeling exercise or is it something to be made ?

In essence you can create that object from your screenshot similarly to how this can be done  in Blender (In Blender you can do that with booleans).

1. Create a block  the Model work space using the solid modeling tools.
2. Create a form, which brings you into the Sculpt workspace and crreate your negative form of wha you want to cut away from the block.
3. Finish the form.
4. Modify-> Combine (cut) the two objects.

This is one way you can generate that non-desrcript object. However, the question is wheter that is the right approach gonig forward with teh other part of your design.

Hi Jeff,

thanks for the detailed screencast that helped a lot!

'loft surface' was exactly what I am looking for.

Many thanks!
