I will. I just upgraded to pro simple for the Configs update.
The company that I work for makes many different styles of parts. Most dimensions on these parts are the same, only the length hole size and tapper change between each part. Our parts have a thread on one end that is common to all of the parts. On the other end there is a hole. Also the hole end OD is tapered to a set dimension over the hole diameter.
With configurations I can model the basic part once.
Then for the next style I will create a new configuration.
To activate the new configuration left click on it in the design explorer and select activate.
Once the new Config is active I can then open the equation editor and change the values of the dimensions that are different, and the model will update accordingly.
This way when I create the assemblies with these parts I do not have to model each style of part. I just model it once then choose the configuration that I want in the assembly
I hope this helped and didn't confuse you more.
