variable pitch helix/configs
variable pitch helix/configs
(OP)
Hi all,
I've always used three helix function to represent springs. One tight pitch for each end and one for the body. I could always add configurations for different lengths, including solid heights, as needed. Recently I began to play with the variable pitch option to form both ends and body in one shot. While I can still add a solid height configuration for a given length, I cannot find how to add separate configurations i.e. longer lengths, more coils, etc.
Any thoughts?

So I sketch a line, dimension it, and control the dimension with a data table. I create the helix and link the length to the length dimension of the line in the data table. And this is where I'm a bit foggy on this stuff, but perhaps the line dimension can be controlled separately within each configuration--each configuration having its own dimension.
If that doesn't work in a straight-forward manner, I'd try having separate sketches for the line--one used in one config and the other used in the other config--each with the dimension you want in that particular configuration.

After you create the helix, you can access all the feature dimensions by double-clicking the helix feature in the featuremanager design tree. From there double-click the dimensions you want to change and specify which configuration the change needs to made to. Hope this helps

See Boomers post. Changing the pitch/length on a single detail is easy. Add a configuration, click the helix feature in the design tree, double click the dimension needing to be changed and make it configuration specific.

Sounds like the variable pitch feature for helixes
(heli? lol)does not lend itself to configurations as easy as I would have liked. I'll play with it but I guess it is not that important to have all sizes. I'll get around it with a detail print and table of sizes.
Thanks to all

I've never tried to model a spring. I've always use this one that I got off of 3D Content Central a few years ago. All dimensions are controlled and editted in the "Control Sketch." The pitch is driven by the length and the number of turns of the helix. It is pretty easy to make compressed/pre-load/free-state configurations.
