Error Making Spring!!


I am trying to draw a spring but i am doing one turn at once and then another turn until n(number of turns), but when i use BRepOffsetAPI_MakePipeShell or another function to do a pipe always remains a blank space where the Shapes doesn't fits, so my final shape when a use the BRepAlgoAPI_Fuse is not correctly. How can i fix this? I left a image of what i am saying!!

Thanks for your help!

Hello Gustavo Garcia Gonzalez,

I think you can refer to the bottle tutorial: the bottle neck thread section.
Make the spring by the pcurve, i.e. curve on the surface.

I have tried this, it works fine!
