I’ve tried to build this spiral stair and using followfy plugin and truebend as well, but so far I have the same issue that the upper part of railing and the vertical part are not the same width. How to make them equally? Appreciate any help and suggestion
Without a model to comment on… Assuming that the ‘wood’ part is separate - draw some guidelines from, the three edges near the white part, these will give you the edges of the 'wood’s to edge.
You could copy Move+Ctrl the three white edges perpendicularly to their plane and use those to for you guideline locations.
If you won’t give a more detailed description and share a partial model of the problem we can only guess…
I’ve already shown you how to create that stair using Shape Bender. You will get a clean model with the two parts of the railing with the same width, as you want.
