Sharing well model construction tips and well constructed models
Sharing well model construction tips and well constructed models
(OP)
A long time ago, I posted a couple of threads ( http://eng-tips.com/viewthread.cfm?qid=234523 and http://eng-tips.com/viewthread.cfm?qid=234523 ) where I shared a couple of models which other people might have found useful and the thread went on for a good while with people finding quite useful.
Any how, I have just been asked to create a part family for some spring washers and decided to use the excercise to brush up on my modelling skills as I haven't done much in anger for a while and therefore I created the family master so the whole family of washers can be created by simply changing one simple expression - bolt_size - the model itself is relatively simple, but look deeper into the expressions and in to the features and you will see that there is lots going on.
I have created conditional expressions using a couple of different techniques and if you edit the expression bolt_size to be any of the following values, 2 - 2.5 - 3 - 3.5 - 4 - 5 - 6 - 7 - 8 - 10 - 12 - 14 - 16 - 18 - 20 - 22 - 24 - 27 - 30 (metric bolt sizes) you will see the washer update in terms of its internal and external ID, thickness, number of teeth etc. You can also edit the angle of twist of the teeth very easily.
I'm also keen to learn, so if there is a differnt or simpler way I could have achieved the same out come then, I'd love to know. If you have some well built non-sensitve models that you'd like to share, then post them under this thread.
Enjoy!

You linked the same thread twice btw, just thought I'd mention that.

RE: Sharing well model construction tips and well constructed models
To me, using an expression would only be beneficial if I had a single part and changed the size depending on the application. All parts would have the same part number/name, so in a BOM you couldn't tell if it was a 6 or 10 washer size.
