Quick way to do this?

[matt.culik]

I'm working on a socket tray that I plan to laser cut from EVA foam. Here's what the whole thing looks like:

My original thinking was that the kerf of the laser would open up the space where the individual socket holes are tangent to each other. It does, but not as much as I'd hoped it would. I ended up with very narrow, pointy pieces of foam in between the sockets which are going to get destroyed with use.

So, I'm trying to do what's shown circled in red below. To do this, I created some offset lines and trimmed the space between the lines, then applied tangent arcs to each "point." However, doing that for every socket hole is going to be a huge time suck. 

Does F360 have some kind of "trim stamp" that would allow me to click where the circles touch and replace it with two tangent arcs at some offset distance?

Thanks!

Extrude the foam as it is.

Apply Fillets to the model, then take a new sketch from finished face.

Those blue lines should keep you awake for a year or two.

Might help....

@davebYYPCU - What do I apply the filet to? If I extrude the foam 12mm, which is the real life thickness, I get what's in the screengrab below. F360 won't let me filet the vertical tangent line between each circle pair.

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

Correct, you extrude cut the gaps first.  (centre line rectangles.)

Apologies for the delayed reply. Got sidetracked with other stuff. 

@davebYYPCU - Thanks! The approach you suggested would definitely be more efficient, but still requires me to make rectangles in each line of sockets. 

@TheCADWhisperer - Please see attached file. Note the 2D part is my working laser DXF - basically just a copy/paste of the 3D stuff cleaned up a bit to make it easier to work with in my laser software.

If center rectangles are the best option, that's fine and I'll get after it. But if F360 has a better way, that would be great from both an efficiency and learning perspective.

Thanks.

One fillet command, is not suitable?

My workflow with inspiration from @davebYYPCU.

• Sketch Center lines.
• Thin Extrude the lines.
• Ruled Ruled on Thin Extrude Feature.
• (Give Fusion some time to compute.)

Ruled Ruled on Thin Extrude, don’t know what that is, figured it out, Ruled Fillet on .....

I suggest rectangles / trapezoid for user decisions on gap size, in sketch, then Extrude foam is one selection.

Front view and window select vertical point edges, set fillet value.  

Two timeline features from the completed sketch.

Might help.....

Thanks, everyone! Learned something new with Thin Extrude and Ruled Fillet. Those two things will work very nicely for this project.
