Conditional lines on part cylinders

[Ronald Vallenduuk]

Why do the part cylinders (n-fcyli.dat) have a conditional line at their edge? One control point lies inside the part but the second one lies outside. In a lot of cases that outside one will be wrong. When it is you have to add another conditional line with the correct control points but that means you have two lines in the same position.
I guess this is one of those things that are now impossible to fix because of the sheer number of parts you'd have to update.

These control points are correct. If you add a tangential face to the cyli, then the control point matches this face.
unfortunately you need to add extra condlines when the connected face isn't tangential to the cyli.
I hope your question is solved?!

If you add a tangential face to the cyli, then the control point matches this face.

It also works if you join too partial cylinders together, as those side condlines complement each other. So for most usages, these condlines are OK and avoid the hassle of creating them.
It's only when you join to a surface not tangent that you need to add another condline.
