Hello.
I'm fairly new to CAD, but I know most of the basics.
I am trying to design a spring with 2 inefficient revolutions (1 on each side) and 9,5 efficient revolutions - 11,5 total. Firstly I sketched a circle with a dimension of the middle diameter of the spring. Then I created a helix with a variable pitch/rotations (the height of the spring matches the desired height), and a circle piercing the helix. When I try to create a sweep boss/base I get an error saying 'the sweep operation failed to complete'. I'm guessing the thickness of the circle is too big to complete the sweep.
I am attaching a file of my helix sketch.
Could someone please help me design the spring?
Thank you in advance!
Hi Valentina,
You are correct...the 6 mm diameter spring causes a failure due to the parameters you have at the bottom of the path.
(Pitch = 6mm. , Rev = 0, Height = 0 and Dia = 50 mm.) I have attached two images:
Figure 1
Figure 2
You can depending on your design intent:
1) Keep the path as is and reduce the diameter of the wire, In Figure 1, I reduced the diameter from 6 mm to 3 mm.
2) Keep the diameter the same and increase the pitch for Rev 0. In Figure 2, I increased the pitch from 6 mm to 9 mm.
