[man44k]

Hi,

want to learn how to make something like jig/support under the part. Something like this in 6:50

What i need to make first sketch project? And around a corners?

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

How much Fusion 360 (or other CAD) experience do you have? 

(This is not a project for a beginner.)

I've done everything in catia until i change job. Now at work i have fusion 360. Here i post example part, i don't think that i can share that mode in public.

But basically what i do, i made project with offset of that part in every direction. Loft surface, but the project is not that accurate and need to make close points. After it i made box, combine cut that part and cut it with projection.

But now i can't extrude part.

So i make something like mold but i only need bottom with extrude option

I had a fair bit of trouble projecting all external lines and splines etc. Will you build up a solid body?

Warmingup1953 thx for the idea i just made the solid body and combine together. Warmingup1953 i would like to ask if you could point me out how u do that curved projection of what u did.

With this curvature, I could better measure the length of the extrusion.

I also attach the model i did if u have any suggestion to do better please post 🙂

I've got another question is it posible to do something simmilar like in the video 5:03 https://youtu.be/yp9FsuwA-ro?t=303 

In short to make projection of edge in some offset like those lines in video.

Yes...I did say I had difficulties! I projected all the silhouette geometry from the Catia body I recall but could not achieve an extrudable profile so I took that sketch as a .dxf into CorelDraw. The issue was overlapping and duplicated splines that I excluded to the old-fashioned way by set moving the good and leaving the bad...The blue lines etc on the left were left behind as they were either superfluous or duplicates and that blue outline I saved as .dxf and brought back into Fusion 360...I'm pretty adept at this having spent the last 3+n decades attending to substandard .dxfs!

I've attached my File if it is of any use
