Fraction circles - centres too sharp

[Brittany (Brittanybalinski)]

Hi, please see the image. When I cut this, the central angles will be way too sharp. How can I round these off? Thanks

If you create the shapes as closed pie pieces you can use the radius tool to round off the corners.

Or, if you want to minimise the number of cuts and/or material used, add a very small circle to the middle of the large circle.

I can give this a go, I think, but could you point me in the direction of a tutorial for that? I’m fairly new to lightburn. Thank you for your help!

I’m not aware of a tutorial that would cover that but here’s what I would suggest:

1. Create circle
2. Create rectangle that covers one half of the circle
3. Select the circle and rectangle and then use Tools->Boolean Assistant and one of the “subtract” operations to remove the rectangle from the circle.
4. Create another rectangle rotated to 30 degrees covering all but what would be the equivalent of one pie piece
5. Repeat boolean operation to leave you with one pie piece
6. Use circular array tool to duplicate the shape for a total of 12 pieces. Note that there’s an option to “use last selection as center”. You can take advantage of that by creating a temporary circle that you place at the center corner of the pie piece so that the circular array tool rotates around that center. Simply delete the shape after the operation is complete.
7. Use radius tool to round each corner

You are very kind. Thank you
