I posted last week with some issues surrounding a helical staircase I am drawing up and gratefully received lots of help and was able to sort the problem, however I am now having a similar issue with a different part of the helical staircase. I understand that where the straight run turns into the helix on the staircase the the angle of ascent changes and I know how I want to blend the two bits together but I have not Idea how to create the shapes required. I have tried various plugins to help including Curve Maker and Draw Parametric Curves but I still cannot get the two sections to blend. I have attached the file which has my model on the left (darker grey) and the rough model I am working from on the right which shows the look I am trying to go for. If anyone could help me figure out how to create the desired shape that would be much appreciated.
