Need help createing this surface

[karthur1]

I have brought a surface into Fusion.  The width of the surface varies around it, but it is approximately 1.6mm.  I am needing to get this surface to 6mm in width. I was thinking I could create an extrusion on the "inside" surface, then offset it 0.8mm.  I was going to use this new"center" extrusion and offset it 3mm in each direction.  I would then extend the original surface so that it intersects the two new surfaces.  I will take this to build a sculpt.

Is there a more simple way to create this?

I exported my part and I have attached it here. Maybe there is an easy way to share my design from my Fusion Hub.  If there is, I have not found it yet.

Thanks,

Kirk

Hi Kirk

its something like this?

How do I view the attachement?  There is no .f3d file in your zip.

Hi

I tried to upload to here but the size was to big, and the link is right.

When you download the file is .ZIP, just change it to .F3D

is some kind of bug of issue about the forums I think

[karthur1]

Ok... got it.

This is dufficult to explain and I probably did a terrible job in my original post.  Sorry about that.

If you look at my part, there is a "Body 4" under the unstitched folder.  That is what I am building from.  The width of that "ribbon" varies, but it is about 1.6mm wide.  I need to increase this to be 6mm wide. I need it to be 3mm wide each way from the center of it. Basically each edge will move away from the center 2.2mm.  I first tried to use the "Extend" command to move out each edge.. something like this

..... but I could not get that to work. I am using the "Tangent" extend type here.  If I change to the "Natural"extend type, it will work, but one of the corners does not work exacly correct.

So then I set off projecting the edges to a sketch, and I was planning on offsetting the sketch the distance I needed.  The "Body 48" and Sketch4 was my attempt so you can delete that if you want.

[karthur1]

I was able to use the extend command and get the outer edge to work.  I used the Extend command twice.  Once with 1mm offset and then again with the 1.2mm offset.  Then I did the inside and it looks much nicer now.

Now I have another question.  I would now like to extrude this surface down to the "extrude4" that is below it.  Is there an "easy" way to do that other than projecting the edges to a 2d sketch and then projecting that?

Thanks

When I project the edges to a new 2dsketch and then try to project it back up to the "ribbon" surface, I get this errror "Failed to terminate at target body/face!"

Suggestions????

Instead, try lofting from the source face to the planar sketch.

Kevin,

That helps.  I got it extended like I wanted.   Now I need to add a fillet between these two bodies.  I am trying to add eht fillet here, but it will not pick that edge when I am in the fillet command.  I suscpect it is because the Body53 is an "open" body because of the icon in the browser.

I tried to use the Combine tool to add them together,  But it will not pick the second body.   To get to this point, I used the split body tool, then deleted the portions that I no longer needed.  How do I add the fillet in this corner?

Thanks

1. Switch to the modeling workspace
2. From create pane choose boundary fill
3. Select the two bodies you show in the bowser
4. Choose the "cell" section in the command dialog and choose both cells by clicking the empty checkboxes that show up in the graphics near the volumes you want.
5. In the command dialog choose join.

The boundary fill command will combine all cells you choose into a single solid. you then "should" be able to fillet the edge you want. This geometry is messy so I wouldn't expect a huge fillet to work here.

Kevin,

Got it done with your help.  Many thanks.

I was just looking for .125in fillets in those corners (both inside and outside).  The outside ones worked, but I had to delete some of the faces to get the inside to work.

Go the hard part done though.  It is much easier to work on this type geometry here than in Inventor.

Thanks for the help.

Glad to hear that!

Is this an EDM electode?

[karthur1]

Looks like it, but its not. This is actually a weld tool for an automotive lens assembly.

[schneik-adsk]

Interesting. Sorry I keep asking questions. So then is this for sonic welding? I'm always interested in how these digital models become real and have a background in MFG so I'm keen to learn what types of methods customers use.

I'm glad to hear it's not EDM. I spent way to much time with sink EDM machines and that smell... well I'll never forget it.

Kevin,

This welding assembly is the "Hot Plate" in a thermal welding tool.  It welds the lens and the housing together after the LEDs and circuit boards are placed inside the assembly.  I have not completed the assembly that this part is going in yet, but attached is a similar one that I completed using Inventor.  It was a struggle in Inventor to make the parts match the surfaces of the plastic parts. Hopefully, I can use Fusion as a tool to complete this portion of the assembly.

The arrow is pointing at the "hot plate" in this assembly that is similar to the one I was working on in this thread.

Cool to see all the mfg. process of a product
