Fill Surfaces

A fairly straightforward fill surface was the first object to be contoured with UDF's.  The fill surface above receives 5 to 25 UDF contours.

various positions and projections of contour lines on the fill surface

Closed Multi-Section Surfaces

The closed multi-section surface above receives 5 and 25 contours.  For a closed multi-section surface.  The previous method of projecting a line doesn't work.  Instead, I created a series of parallel planes that intersect the surface, creating a closed line at the intersection of the two.

The multi-section surface was formed with a series of 3 splines.

UDF's are composed of a point at a certain position on a vertical line, a plane positioned at the point that is normal to the vertical line, and a line formed by the intersection of the multi-section surface and the plane.

Open Multi-Section Surfaces

The open multi-section surface above receives between 5 and 25 contours.  The same method of using planes to form intersection lines was used here, but in this example, none of the sketch planes are parellel to the intersecting planes.  This means that not every intersection line stretches all the way across the surface.  As you can see in the image above, some intersection lines stretch across the entire surface while some only stretch across a corner.

Two sketches were drawn and then combined to form a spine for the sketch planes.

Three planes were positioned normal to the spine.

Sketches for sections of the surface were then drawn on the planes.

A multi-section surface was created with the three sketches.

A straight line was drawn from one extreme of the surface to the other.  I intentionally drew it off axis to the z-axis.

UDF's are composed of a point at a certain position on a this line, a plane positioned at the point that is normal to the line, and a line formed by the intersection of the multi-section surface and the plane.
