Summary0001722: Left-handed helix with an angle>0 produces 1 too many turns
DescriptionLeft-handed helix with an angle>0 produces 1 too many turns.

Looks OK for right-handed helix or with angle == 0.
For long helix (height/pitch > 50) the problem is only in the first part where there are two turn instead of one.

Also (GUI) negative angles are ignored therefore better be disabled.
Steps To ReproduceSelect "Create Primitives..." from the Part menu.
Select "Helix"
Select values (I use Height=100mm, Pitch=100mm, Radius=50mm".
Select an angle > 0.
Select "Left-handed"
Click "Create"
A helix with two turns is created (should be 1).
