Hej Lagom. Thanks so much for your time. I think I read 15 times your answer in order to understand it.
It is quite frustrating, I ve have been using RH for 15 years maybe , but never stop to think about continuity on surfaces or curves. Still I manage to get quite complex surfaces although I am sure if i applied a Zebra map I can understand why is important to master the ‘continuity’ aspect.
Regarding your answer:
[first paragraph you wrote]
I understand you rebuild the arched strips in a way where the surfaces is composed by different ones. Where every surface starts and ends (lets say the rials) where the limits of my ‘base’ surfaces edges appear. So I will try by doing this by parts as you show. Still I am trying to figure it out how you decided the arcs of the start and ends of each surface. I am trying to build this on a cnc so I would like to have control of this arcs. What I imagine I can do is to:
- Use my 2 intersections with the base surface (rials) and execute sweep2 with the arcs/curves I need to control:
A. Curve on the bottom of my ‘base’ polysurface. This is a curve coming from a blend (tangency on 2 ends). Degree 3.
B. Top Curve, same principle than the bottom. You can see the intersection points in respect of the rials ( green / red ) are a little bit lower since the lid of my base polysurface has a depression.
Overall strip before applying your technique:
The reason why I do this first is cause I need to extract certain curves in order to reconstruct the lid surface.
What I want is to flow through these rials from the bottom to the ‘lip’ radius of the lid in this specific way and then I need a transition to the flat surface.
SHOULD I DO THIS ? ?
I hope this shows how I am imagining to re build my strips with your help.
Again I would like to use the curves I decided on my first (light blue strip).
I think the reason also of that many isocurves on my first attempt is cause now that I explode the rials…they are crazy
messy. I guess the intersection is not that precise in terms on how it understands the curves on the base polysurface.
Lagom this reply its getting long. I came to visit Krakow, but I could not resist stop thinking in this surface I want to CNC.
I saw your reply and went straight ahead inside a coffee to check it. I really appreciate your help.
As soon as I make a new break on my day I will get back to you to discuss the second paragraph and just clarify how I am going to CNC. I will receive help from the CNC operator at my school in Oslo. He has an idea. I think we are going to split it as a box. I will explain soon.
Thanks so much.
