One possible method:
With Section > Create Group from Slice, you would get the 2D model which you can then simplify (Fredo Curvizard). Create the faces and with PushPull you get the low-poly 3D model.
Thank you so much! I am trying to learn! Just tried to use flowify on a new stair rail I made to see if I could do it myself with a simpler rail and its still not working! Could you have a look at it?
I have clean up - downloaded that extension the other day! I have literally spent the last week trying to perfect these extensions! You are literally a life saver! After my deadline I will go back in and perfect the extensions!
Did you read the whole discussion? Have you checked your model and tried to apply what was discussed here?
Do you know if you created the groups correctly? But the geometry inside them?
