How to create a separate compressed length & loose spring length CAD model of a spring in Spring Generator

[gcross]

I created a compression spring in Spring Generator for a Ball Plunger that is sealed up inside the assembly at minimum load. I need to create a drawing showing the compression spring in a unloaded, loose spring length for manufacturing but cannot figure out how.

Placing a view of the spring always yields the spring length when under load as it is in assembly (at .243" length). The loose spring length is .3125"

How do you create a CAD model & view of the loose spring using Spring Generator?

Hi

I don't think this can be done in the generator itself.

You can open the part file and create a new model state with the expected length parameter. Search for the parameter(s) responsible for the total length and match it(s) to the expected variant.

In the drawing, you can both insert a base view in the selected model state and create an overlay view with such variants.

Here is one of the ways to get it done. IV2020 file format.
It is jus a random spring. But for the spring made with Spring Generator - the same approach can be used.

Cheers,

Igor.

Igor,

Inventor is looking for a part1.ipt file when I open the spring.ipt file. I thought that might be an .ipt template file but it did not work.

Can you supply your part1.ipt file?

Thanks!

Could you utilize model states. Place 2 instances of the spring (1 loaded and 1 unloaded). Then create the appropriate model state and choose which spring is to be in which state. Then you can place that spring into an upper level assembly. Now, repeat and make the model states there showing which version to use. Please see the video for the concept.

Hi Gary,

Yes, it does. The spring was part of the assembly. There is a d3 parameter (controls the diameter of the spring in relationship to the cups) from Part 1, which is referenced by d0 parameter in the Spring.ipt. 
In this sample I have removed that link.
Cheers,

Igor.
