Cutout

[REDnumber5]

Thank you, I was thinking about it all wrong, I'd drawn the lines and arc's and was thinking there was a way to somehow fill it in.

The "capsule" is a cylinder + 2 half spheres
If you want precision just draw more segments in drawing the half sphere

Hi REDnumber5, hi folks.

See attached SU file for ideas.

Curved notch.skp

[pilou]

Yup but you have also a capsule soon ready and parametric inside the Skechyphysics tools' plug

Here is the first thought I had. Draw the U shape, draw a cirlce and FollowMe along the U, Intersect and delete. But I am not sure if it is the right shape. If I made the arcs the same as the circle, then I think it would be OK.

Seems it's not exactly the same

[Jim]

What if you make the arc radius 1/2 the circle radius?

[pilou]

seems that make not 90° between horizontal section and vertical section so can't be a 1/4 of sphere

[REDnumber5]

So I took a 1/4 sphere and moved the endpoint to the drawn arc on the face, then scaled it to fit and moved the outside points to match, flipped, moved, pulled, intersected and deleted the unwanted lines. I could't get it to match perfectly bcause the drawn arcs had more endpoints than the 1/4 sphere, maybe with a little forethought I could specify the the amount of segments to edit exactly. Or is there a simple way too add points in the middle of a line?

Thanks again

I didn't show the inbetween steps here, I hope this makes sense.

[pilou]

Yes that makes sens
1/4 of sphere is logical and simple but in fact you can take any variation of that, depending of what you want as angle for your cut out

A middle of a line? there is an hot point of the middle of a line, so redraw over start to hot point and kill the bigger
