Rectangular spring equation

[TCC2]

I was wondering if there was an equation out there that creates a rectangular spring? I have tried a few different options, but haven't been successful due to the fact I want repeatability in my component. Everywhere I go to get an answer, the best solution is to use a VSS, but the spring I'm trying to create only has a height of 1.5mm, so its too close to the center of the VSS, causingthe spring to"bend" between pitch ends. The example is Variable pitch retagular spring on this forum: [url]http://www.mcadcentral.com/proe/files/gallery.asp?action=sea rch&text=&whichpage=34[/url]Anyone have any suggestions?


Trying to create a part where I would only need to change the numbers in the equation to come up with a different sized spring.

Modeling it through equations / evalgraph function could be one way. I have used WRAP function to achieve the same here.

Here's a quick video on using multiple Variable Section Sweeps (VSS).

I like the wrap feature for this.

I tried the wrap but could not get it to work. Could someone post a sample in WF4 for me to study. I followed the same process as Sirini but in the wrap command, it kept me stuck in the command and would not create the curve. Thanks in advance for the help.

For Wrap feature, make sure you have a coordinate system
at the origin of the sketched curve. Refer help.

Thanks Hrishikesh. I did not have a coordinate system in my sketch. It works fine now.
