Arc with straight segments with loft

in Drawings
Hey,
i would like to draw a arc with straight segments. Here is the link: https://cad.onshape.com/documents/b09e2546059a1c9df86d6cf9/w/6a3d3c8a830438bf837eb0fe/e/db58689cd6160d6ab6fb56da
I made three sketches:
1x Loft, i choose the Loft tool and select all intersections. The segment are not straight, they are bend.
1x Loft with Guides, i draw two outside outlines at every segment and choose them as guidelines. This wont work... i dont know why ?!
5x Loft, i make every segment with one loft, this works the segments are straight.
Is it possible to to it with only 1x Loft and right guidelines ?
Why are my guidelines are wrong ?
Best regards
Kai

It's the same reason you can't have a spline that makes a corner.
If you want straight lines, then change your arcs to ellipses and maintain tangency across the boundary. Or, connect the lines with splines and maintain curvature across boundaries.
