kufloyd Posted February 9, 2017 Share Posted February 9, 2017 I would like to erase half of an ellipse. I tried this by creating an ellipse and adding a rectangle with no fill/stroke lines over half of it - that does the trick but the line of the rectangle is still visible in center of the ellipse. Is it possible for the line to not be visible? thanks. Quote Link to comment Share on other sites More sharing options...
MikeW Posted February 9, 2017 Share Posted February 9, 2017 Draw the circle. Draw a rectangle that is wider and place on top at the mid-point of the circle (if you didn't draw it so it was already at the mid-point). With both selected, press subtract.

Aammppaa Posted February 9, 2017 Share Posted February 9, 2017 Or use the segment tool? Drag out a segment, and position the cut line (middle orange handle) in the center to get half an ellipse. Search Help for Segment to get more info.

gdenby Posted February 9, 2017 Share Posted February 9, 2017 If you want no line, you will have to break the curve. Or never have a stroke. AD shapes are closed curves by default. If you have just vector lines, and try using a boolean operation on them, the lines will automatically turn to closed shapes. So if you just want the arc, you need to use the node tool to break the nodes that are at the ends of horizontal line. The half ellipse will then turn to 2 curves. The straight line can be deleted, leaving the arc section w. just a stroke on the curve, but not on the flat.

PixelPest Posted February 9, 2017 Share Posted February 9, 2017 I´d say use the Donut-tool for a partial circle as workaround (you´ll end up with a doubled line) because it´s not a replacement for dedicated parametric circle tool like Inkscape offers for example.

Cheers P. If the doubled line is a problem, you could convert the object to curves, break it at both ends and delete one of the two resultant semicircles. However, if you're going to do all of that then it's just as easy (and more intuitive) to start with a circle.

R C-R Posted February 9, 2017 Share Posted February 9, 2017 And I would say we have now gone full-circle... Ouch. Please refrain from going off on any tangents like that. They strike a chord that I find very unsettling. So please take a secant to think that over before you post anything like that again. :P Alfred 1 Quote All 3 1.10.8, & all 3 V2.4.2 Mac apps; 2020 iMac 27"; 3.8GHz i7, Radeon Pro 5700, 32GB RAM; macOS 10.15.7 Affinity Photo 1.10.8; Affinity Designer 1.108; & all 3 V2 apps for iPad; 6th Generation iPad 32 GB; Apple Pencil; iPadOS 15.7 Link to comment Share on other sites More sharing options...
