Stive I need this option, in most cases, and this is a common problem

Hi Darcvizer,

The problem is when using "Line_list" or "Zero_tangents" on splines with more than 2 vertex along a straight section.(Vertex tangent flow becomes broken).

When creating "Line_list" splines, only create vertex at the corner points.

Thanks, I often create a spline from the edges, for me this is useful when creating railing and fencing. Is there a way to make a vector spline correct?

With "Line list" splines, it is not possible to edit tangents/flow, as the tangents are removed.
You can instead use "Zero Tangents" and edit those.
But if the result you want is for simple one direction instances(such as for a fence), it is far easier just to change option in "Spline Instance" tab to "No Change"

I will make a bug report with example.

Hopefully, IStonia will be able to take a look at the issue when he has time.
