Curved Table Top Pie Piece in Carbide Create

@ErnieS asked on Facebook how to design this in Carbide Create

Start with a 12" line

image

From the center of that line, draw a 4" Radius circle

image

At 3" and 9" along that line, draw a vertical line

image

Trim those lines to the circle

image

From the newly trimmed ends of each line, draw another 4" radius circle
You can use the ends of the 12" line, or type in 4.0"

image

I just happen to know that when you copy & rotate your “S” curve, it will not be exact. So I’ll draw another line at 45° to trim it to to leave the right end a little long.

image

Trim the curves to look like this

image

Delete the construction geometry, leaving just the “S” curve. There will be a tiny bit of overlap in the center. trim that section too, then join the curves.

CTRL-D to duplicate the curve & click anywhere

image

Rotate the new curve 30°

image

Select the left end of the new curve & move it to the node on the left end of the other curve

image

Draw in your 12" radius circle

image

Trim the right ends of the curves to the circle, and the 330° section of the circle

image

Join the curves

image

Of course, this is ONE way. I’m certain there are others. :wink:

That’s an intellectual way of solving that and well-done! I might have just found a squiggle line drawing on the interwebs, traced it and then cleaned up the stray nodes to get the curves looking neat.

Your way is way more precise and looks great!

Good point. Theoretically, any shape rotated 30° (or any factor of 360) would fit together. And a hand drawn, non-mathematical curve might even have more character. ?? :smiley:
