Clarication on surface cration #8

Open danielecocciolo opened 7 years ago

danielecocciolo commented 7 years ago

Hello, I've a problem using the library. This the problem. I have 2 couples of curves: 2 straight lines, and 2 arcs. I created 4 different sislcurves object and then tried to create a surface. Here is the problem: how can I create an extruded surface or a ruled surface? The s1538 function create a surface different from a right extrusion that not respect the four boundary curves. Is there also a book or a reference to connect coded function with standard geometric theory?

Thanks in advance

Hi,

Try s1538 to loft with a degree 1 (order 2) surface between the arcs.

Hi, I have doubt about what I'm viewing with my nurbs viewer. Can you help me? I'm not a programmer and I have some trouble compiling the viewer in the example folder of sisl archive. Can you send me the compiled viewer for win7 32bit?

Thanks Daniele Cocciolo
