Creating Curved Table Rail

[Anonymous]

Hi,

I'm new to Fusion so I may be completely on the wrong track right now. I am trying to model a table rail to cut with a CNC. I sketched the evelvation (front) view of the rail and then extruded that sketch to the thickness of my material (1.75"). Then I created a new sketch on the "top" plane to indicate the plan view of the rail (see screen shot). How do I combine the new sketch with the origional sketch to create one 3D model? Am I one the right track at all right now?

Any sugestions or links to learning videos would be appreciated.

Thanks!

That looks fantastic! Yeah, the buttons are wierd. The whole part will actually get carved by hand after it comes off the CNC so the buttons are just extra material to create an acanthus leaf type termination to the sweep. Here's a pic of what the piece will look like completed.

Aha. Making it wider was qute a challenge but a nie and educational one.

If the bead profile is consistend throughout it's length AND it's not an exact half of a circle but rather just a segment, then instead of usion the pipe command used by @donsmac it is only slightly more complicated.

I'll may be able to make a little video of the overall process tonight, or perhaps a written description with screenshots is better ? (or both ?)

Yes, I was not sure how you imagined the buttons to look like so I made just something!

Are you  aware though that the flower pattern can also be modeled in Fusion 360 's sculpt environment and then combined with the Solid Model shown so far ?

I am sure @Donsmac could show you haw to do that out in no time!

Well I'm glad you got something out of my bad sketching! Sorry about the confusion!

A video and/or tutorial would be really great — whatever you feel like you have time for. I really apreciate all the help.

I did figure that it would be possible to model the carvings as well but I felt like I needed to draw the line somewhere for my first 3D project. It would be nice just to carve out the outline, if nothing else — that would make the hand carving go faster. If any of you guys felt like doing a tutorial on that, it would be awesome but I totally understand if you are getting bored of this project!

Thanks again!

This was done rather quickly. I could have spent more time sculpting the leaves and petals but just I wanted to show here how you could start. 

I made a screencast of the process.

Wow, thank you. That is very cool. The point you are at at the beginning of the screencast — did you get there using the same splines as when you were creating the details inside the petals? 

Honestly, that is probably more deatil than I would ever need to create with the CNC. What would the best technique for me to use if I just wanted to define the outline of a carving that I could then complete by hand?

Thanks again!

You can define the amount of material to be removed in your CAM settings, so make the model as detailed as you can.  Once you've selected a CAM operation, go to the Heights tab.  There you can set an Offset from the bottom.  There is also Stock to Leave settings on the Passes tab.
