Fusion 360 - Help with surface sweep of sketch along two paths

Hi, I have two edges either side of a blade and I'd like to run a sweep of a sketch along between the two edges.

 

See image

 

Can anyone assist me with how to do this please?

 

I have highlight one edge, the other is the opposite side and you can see the sketch which is a simple arc that I would like to run the full length between the two paths.

Your need to attach your model so the Forum users can look at something other than a picture.  If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

Hi, thanks for that, I've attached the full file now.

 

I'm trying to build a blade for the rear of this car spoiler.

 

I wish to create a cross section down the full length so the front edge of the blade runs flush with the body part which can be seen MeshBody1 

 

Ideally I want to run a sweep the runs all the way along the front edge and the rear edge (I have split the solid blade to create this back edge.

 

Any ideas welcome

If this were my design:

1. I would start over with Capture Design History turned on.

2. I would fully define each and every sketch...

I've looked at all the geometry and sketches in your design and to me it looks like you are experimenting with workflows rather than just outright designing the object.

 

My suggestion would be to start completely from scratch with a design with an enabled timeline.

It looks like you've tried this a number of times already ...

For example here

Yeah, I realise, but I am not you and I've spent too long now to throw this all away.. I'm having to experiment because I don't entirely know what I'm doing which is why there is so much mess..

I know, it's because I'm an infrequent and inexperienced user...

I've spent so long on this I can't start over...guess I'll keep experimenting for now...

Whenever someone says this, it's a sure sign that they do, indeed, need to start over.

 

not exactly sure what your trying to do.  one thing I see is that your profile sketch isn't actually on the face of the object-

minute errors like this will eat your lunch when trying to do things in fusion.  there's to much going on in the model for me to tell how it got like this.

 

also, the edges you're proposing to use for the sweep are made of many tiny little segments, and have horrible curvature quality.  that will be problematic also.-

Hi @TrippyLighting, I'm going to take your advice and try and recreate this thing...

 

I'll work out how to enable the timeline, not sure why it wasn't turned on as I didn't turn it off.

 

I'll recrearte the thing without all the mess and label everything.

 

Hopefully I'll end up with something a little tidier...and will then come back with a better project file to examine.

 

I'm doing my best, but without any training, same as last time...learning as I go...

 

Many thanks for your help, it's always apreciated.

Something that would help is to have an image of how you envision this to look like.

Then it is also important to know if this is "only" foe visualization, or if you intend to manufacture this in some way.

 

If you want to "make" it, then we need to keep that in the forefront right from the beginning!

OK thanks, I will be 3D printing this and actually fitting it to a vehicle, so yes in a sense, it will be manufactured.

 

The last one I designed...and you helped me with...I have now sold on the .stl and others have printed their own... I'd offer you a percentage but at £30 a piece and only two sold...hardly worthwhile!!!

Ask questions early and often. 
I recommend that you Attach your new file after each and every sketch and feature.

Thanks Guys, sorry if I seem frustrated at times. I know what I want to do in my head but because I'm such an amature...!

 

To give you an idea, it's meant to look somethign like this when finished but obviously the front edge will be flush with the shown mesh surface and I need to clean up the rear of the blade so it ties in nicely.

 

Give you an idea though...it's a small blade on the rear of the car spoiler to extend it back and up slightly.

 

I've used a section sketch technique to reverse engineer the spoiler, then copy/rotated it into place. I've then cut away the original spoiler to form the underside profile. I now jsut need to get the top surface fitting correctly and tidy up the rear of the blade without changing the profile too much along the back edge... Hope that all makes sense...

OK, starting from scratch.

 

New project created RS4_Spoiler v20

Rescaled

Aligned to centre

Renamed Mesh - Original Mesh Body (Spoiler)

Enabled History

 

Next step - recreate section sketches, spoiler surfaces and spoiler body (ready for manipulation)

Nope! I did not see that you were trying to re-create from a scanned Mesh.

It makes no sense to create that many mesh section sketches. 

The scan is missing the most important surface, the interface to the vehicle!

I'm sorry I do not understand what you are saying..?

 

I have to create that many cross sections in order to capture the detail of the surface as I will use this surface to cut the contact surface of the body I am creating. It needs to be highly accurate in order to create a perfect contact surface.

 

See the latest model attached.

 

I was next going to use the 'Loft' to create both a solid copy that will form the basis of the extension and a surface copy so that I can cut away, creating the profile to which I can attach the extension to the original.

 

Am I going about this all wrong??
