better way to skew a semi-circle
better way to skew a semi-circle
(OP)
Attached is a file where I am practicing skewing a semi-circle(ie. little more than half a circle actually).
The bottom circle is symmetrical. The top one is skewed by trimming the symmetrical circle up then offsetting the tangent curve then adding bridge curves.
Are there other methods to accomplish this? Thanks.

It isn't a must to be able to control the skew with expressions, but I would like to.

In your example , you have three pieces of circles plus two bridge curves, the circles will always be circles, with constant curvature, is the design intent to get a overall smooth curve or should the profile be circular on the top plus lower ends?
If the later, you should be on the correct track, If you go the spline direction, the number of shapes is infinite but can be controlled. - for example add construction lines in the sketch to control tangent directions of the spline.
Attached is an example in the upper sketch, i have kept the circles but made them "reference". The new spline is snapped the upper circle and thereby controlled by it. The lower ends are tangent to the two lines.
