Creating dished surfaces

[design-engine]

This techniqe uses all four part boundaries to nail her.Will discuss the influince curves some in detail at the end.

This model is built with four part boundaries and uses an influence curve. (I have experimented with alternate uses for influence curves and found many places where one could use this in a production model)

Notice the two curves that stretch across and attach at PNT1 thru PNT4. This is the part of the four part boundary.

The final four part boundary.



Influence Curve: This is an option for boundary surfaces. Place a curve as if it were an internal curve. The advantage here is that this internal curve does not have to touch the end of the boundary. It can hang in space and acts on the surface as if modifying internal CV's of a surface. That is a hint on how to weild the influence curve as well.

I use offset with Draft feature to create dished or dimpled surfaces, then use the surface to cut awayView attachment 3826
