spring compressed

hi experts,

Drawing a spring by using spiral, and changing the height.

The spring will be connected like this picture.

How to let the spring not to connect it ?

thanks

By "connected" do you mean overlapping (solids)?

I am not sure what method you used to build this (maybe attach your IPT here) or which version of the software you used, but a "Spiral" is a named METHOD inside the "Coil" function, and spiral coils extend outwards from the starting radius, and not coiling upwards, for ex.

Anyways, here is one illustration below of how you might wish to make a simple spring, and it also shows how it will give you an error (at least in Inventor 2022) if you select a PITCH that is equal or lower than the spring wire's diameter. This ensures no overlapping solid:

If your model has to be a bit more refined you can also use the Component Generator tool for compression springs:

@Gabriel_Watson

Using Inventor 2021.

Yes, the solid is overlapped.

and the method is used revolution and height.

Once changing the height ,the solid will overlap.

Both Inventor 2022 and 2020 could not create coils with overlaps here. I would recommend sharing your sample so we may understand better how you made it, and what was your intent.

I alert that parameter, so that the solid can be show overlapped.

Please reference the data.

Un-check "Close Start" and it will avoid overlaps:

Is interesting. The new added option allows to create a false geometry. The option is not available in IV2020.

Cheers,

Igor.
