I made up a challenge of how to construct an elliptical, spiral staircase on the attached surface (it could be wider, it’s really just a hypothetical exercise, not a real-life example.
I was experimenting with shape blender, which is a very impressive plugin, but I couldn’t define the right spine to make it work. So that would be interesting to know how to define a spiraling spine if you have a geometric or elliptical shape like the one attached.
I should have used 25 segments to make the original ellipsoid curves…but is there a way to correct this? I tried altering the number of segments in ENTITY window, but it isn’t accept any changes
I achieved this through a rather unclever - manual - way…by connecting the division point on the curve…rather than finding a way to modify an existing curve into a curve with the right amount of segments …
Yes, it definitely solves the problem in the case of a simple staircase…I think I was going this way too, but as I was focusing on using Shape Bender in order to be able to automate the process…and be able to use more complex straight stair designs…but it is possibly a step too far…
I was wondering how could I determine the right spine to make a “ramp” between these two landings…I am thinking that if I could do this then it would be one step closer to the solution above. But in reality, I don’t really have it figured it out, so it might just be a dead-end street…never the less, this problem is buging
me now…
elliptical cone shape…
Manually, I can do it, but not sure if I could find a smoother solution when I have smoother segments…It is always easier to work with segments, because it simplifies the curve and makes it workable, but alternatively, I feel that the final result should be smooth…
for example, if you want to send the sections for laser cutting or printing…
