The option "turns" only works if you set "length (mm)" to 0.0.
|
|
Otherwise the length value will be used to calculate the
|
|
spiral for given length. The higher the "step" value is
|
|
set the better the accuracy is. If you set the step value
|
|
really low the resulting length will not be precise and
|
|
the curve is maybe not drawn at all. You can validate the
|
|
length by using the extension "Visualize Path > Measure Path"
