Hi Corliss,

 

That's what I would expect to see from a 4pt srf. If you want a crease running between the two lower points then you could try two three pt srfs. Input D is optional on the 4ptSrf component.

HI Danny,

 

Thankyou very much for your reply.

But for the V-shape, it required 4 points, are there any other ways to create such a surface?

hey corliss,

 

i would suggest the same solution as Danny Boyes did. Could you may be be more specific or add a sketch to explain the output you are looking for.

 

Best Regards

 

Johannes

I see now. Those are Trimmed Planar Surfaces. Create the lines between the points you want edges along and the supply them to a planarSrf component.

Originally I thought that you had the points on different Z planes and needed something completely different.
