I am in the process of learning a little of the theory behind nurbs curves.
Sometimes I want to create a circular curve segment by entering the correct weight of a control point in a nurb curve segment with equal lenght legs.
The problem is, that this value depends on the angle - supposedly by the cosinus value: It is 0,5 for a 60? segment with equal length legs - and slightly above 0,7 for 90?.
So I have to make sure, that the legs are of equal lenght - then measure the angle - then enter the correct value as the weight of the center vertice.
Or I have to split up the curve and use the nurbs arc tool to create the circular segment.
That's awkward.
When you - the magnificent people at NNA - get around to tuning up the interface for working with nurbs (which I am sure you will undertake very soon, as it is in dire need), you can perhaps be persuaded to include a little tick box in the OIP, that says: 'Arc Segment' or some similar wording - along with a dialogue box to enter a value
When ticking this box, the application should automatically calculate the value, that will get me the largest possible arc segment, if the value is left to its default value (which would be zero).
By entering a different value, the program should add the necessary control points if possible and create an arc segment between them.
