Can I assemble flexible products in inventor under tension?

[Anonymous]

I have got an assembly and one of the parts I would like to assemble if a flexible foam (I haven't yet defined it's material properties). I would like to sandwich something between this and a rigid flat plane, so that the flexible foam is stretched over the top of this, see cross-section sketch below.

What is the best way to represent this ?

Derive?

How would I do that, i.e. which mode?

Attach your assembly here.

Here is a zip with the assembly and the components.

How would I use the derive feature to do this? Is there a tutorial etc. which shows which of the modes would allow me to do this?

Thanks.

"in general"....You cannot make a part in Inventor that is just a simple rectangular extrusion and then "stretch/deform" it in an Inventor assembly to surfaces like you want..

Just model the part "as deformed"

Inventor can be "tricked" to do quite a bit though with adaptivity,etc..... but you need a darn good reason to want to do so (adds complexity/file size) and I doubt this is a time when you need to do this..

Thaks for the reply. I am happy to statically model the part as deformed. However, is there any way of modelling the size, as it will obviously be different from the flat shape? 

Aditionally, which tools would you use to model the deformed part, to create a fixed width sheet, with a inset shape?

It's been a while, I believe you only have two boolean choices in derived parts, subract or intersect. All deformed parts here are created with imates because of that. Or maybe that's different in 2016.

Derp, never mind, that must have been in weldment.

By "modeling the size" do you mean you also want the part in its "flat" state?

my first thought is to use an ipart.. like this.. Then its 1 file with both the flat and formed states..

Obviously this is a very primative shape and you can get as fancy as you want with it. 

edit the ipart table to see what was done..
