coil spring

[hillsville]

Hi,

How do you compress a "coil spring" in EI?

[Tomas Egger]

Ola,

Did you try a spline deformation?

Thanks

Hi,

I've tried the deformation tool -- but I'm not sure about spline deformation?

I will recheck -- but would appreciate if you would explain how a spline deformation is accomplished

Thanks for the super fast response

Ola!

Here a simple project using deformations, but if you need a fully realistic deformation, you will need to maintain the volume of the coil spring, my suggestion is a morph, the coil in the both targets, stretched and deformed.

Thanks

Hi,

Thank you for the sample project.  I got similar results.  I will need to maintain the volume.  Is there a good tutorial on how to use the morph tool ?

Hi,

I found the morphing tutorial.

But -- I'm doing something wrong.

See attached - EI isn't liking my target , i.e., naming convention -- or something.

Help?

Ola!

You need to export separated all the 3 files and Import only the first one and after that add the morphing target over the imported one, select the final target model.

I did another method which can help you, do you have Contortionist from Northernlights?
Here the attached project, I did the coil spline in FormZ, imported in EIAS, used contortionist to deform a Ubershape Cylinder and added two deformations, one in the plugin with the same Bezier and another one in Ubershape cylinder to scale when the Coil Squash, Its a another solution which works too :)

Play with the parameters, Its a bit exaggerated in the deforms values..

Hi,

Thanks, again for the insight.  I do have contortionist -- but got an error message.  See attached?

Also, tried morphing got another error - see attached.

unable to upload morphing error?

How do you add morphing targets?

Ola,

Contortionist, delete the Socket folder I sent in the zip file, probably is conflicting with yours and open the file again.

Thanks

Tom

Ola,

Here, a morph test.. please, look the example:

Thanks

Hi,

These are great solutions -- thank you.
