Creating Reference Sets using features?
Creating Reference Sets using features?
(OP)
I have a rubber washer. I'd like to create one reference set with it in it's uncompressed state (2.5mm thick) and another compressed (2mm thick).
I created a simple extrude for the uncompressed state, then added a "Subtract" extrude, to represent the compressed state.
I was hoping to select specific features for my reference sets but I can't seem to do that. It lets me select Datum Planes & Axes, but not physical features (extrudes, revolves, etc.).

Better use family table to create two versions where the parameter of the extrusion is controlling the thickness.
See example (go to tools --> part families --> Edit, under the add-ins tab you find the family table options, choose create parts).

I'm trying to figure out deformable parts.
RE: Creating Reference Sets using features?
Do try creating and using deformable parts for your washer it is about the simplest example that you could begin with. Things to get used to are that you don't edit the definition of deformable parts after you create them you just recreate the whole thing, and they are generally most evident when adding your model (the washer in this case) to another assembly when you are offered the opportunity to vary defined expressions (such as the height of your washer). If you do get stuck being able to hit F1 for help will be your best resort.

Attached is a deformable part which should be close to what you're looking for. Just add it as a component to an assembly and you will immediately see how it works.

I ended up solving the problems with layers. Probably more kludgy than Deformable Parts, but easier to figure out.

RE: Creating Reference Sets using features?
In most cases they are simple parts where you want to vary one or two expressions for a predictable result. To save time and hassles I often create them by including ALL features within the part and finish by defining which selected expressions that I'd like to vary. Things seems to work more robustly that way for a function which can otherwise require analysing things quite carefully.

Life shouldn't be measured by the number of breaths you take, but by the number of times when it's taken away...

However, once the part is added to an assembly you can change the deformation untill your heart is content. Have a look at the entire assembly here and try deforming the gas springs and the rubber mount.

RE: Creating Reference Sets using features?
What you need to do is right click click on the rubber mount in the ANT and look down the pop up menu, you should see an option called 'deform part'? clicking this will allow you to add some deformation and also add a feature to the Part Navigator which you can then edit at will.

RE: Creating Reference Sets using features?
I've constructed a simple deformable part based on your washer example in this thread. While using a dynamic coordinate to condtruct the component allows me to reposition the deformed component in the assembly, it also creates a coordinate system which shows in the drawing. I found I am able to blank this entity but I can't move it to a different layer which would be ideal to keep it from showing in a drawing view.
Creating the part with the coordinate system set to absolute allows me to deform the part in the assembly but will not allow me to reposition the component once it is deformed.
Any advice you can offer to hide the coordinate system or avoid creating it would be greatly appreciated.
Thanks

RE: Creating Reference Sets using features?
Create your part relative to the Datum CSYS, at absolute or any other location, but Hide the Datum CSYS first. Then create your Deformable Part, including the Datum CSYS. Now when you add the Deformable Component to any assembly you will not see the Datum CSYS. Also, once added to an Assembly, you can Move the Deformable Component using 'Move Component' or else use Assembly Constraints to link it to some other Component and then move it.

RE: Creating Reference Sets using features?
Thanks for your quick reply.
I guess I wasn't specific enough about the coordinate system creation. What I meant was the coordinate system was created using the dynamic method which allows you to manually move it about as opposed to specifying absolute CSYS for creation method. The latter does not allow the coordinate system to be moved. If the coordinate system is created using the absolute CSYS method I cannot reposition the component in the assembly if it is deformed.
I recreated my deformable part using your suggestion and the Datum CSYS did not show when I added the component to the assembly and deformed it. However, if you perform 'show all' it will reappear.
Thanks

I found by bringing the component into the assembly using 'original layer' setting the Datum CSYS that gets created stays on the same layer as in the component. This solves my issue.
Thanks again for your time.
