Can't make half a conical roof

[sjsl]

Can't seem to get a half conical shaped roof without some weird workarounds that dont' really work. Can anyone show me the way.

I selected '0' slope, but the rear line with no slope will not build roof, just error meassages.

Is there a better way?

what do you mean "zero" slope? You can't assign a slope defining line '0' slope, you just turn off the slope defining properties.Your semi-circle will be slope defining, and the straight segment will not.

You need to split the straight segment connecting the arc at the midpoint.
