Hi

you have three ways:

1) draw the full circle, draw a box covering the half, subtract the box from the full circle.
2) insert the shape with the Bezier curves, you need to check the doc to get the correct sqrt(2) value in the right place
3) draw with freehand, via Bezier using the grid placed on the radius as help points

Good luck

Hi,

Another option is to set the Section angle to 180 degrees in the settings window for the Circle geometry object.

Best regards,
