iges and movement part

[Stefano_68]

Good morning.

I would like to know what is, according to you, the correct procedure to use an electric motor in iges format in inventor (loaded by the site of a manufacturer) having then the possibility to manage the engine shaft by assigning the rotation movement to it.

Thank you.

if it is an iges downloaded from the manufacturer's site it will probably be a single solid, so you can't manage the rotation of the shaft.
those types of files are provided as aid to the design of plants, they only serve x the footprint.

unpack the imported model into two ipts, complete motor and tree, then put the appropriate constraints to allow rotation.
make a fixed position configuration, which can serve you for setting up the full engine but alone and a flexible configuration, which you need in the set to manage the rotation of the shaft.
We've been doing this for years.
At first we used only one position configuration with angular constraint min 0° and max 360°, with snack on " uses offset as support pos. " but it is a strategy that always creates problems.
Now we use a coincidence between plane and plane, which we suppress when we want to free the rotation of the tree.

How do you break a model in two ipts?

 

[stefanobruno]

make two copies of the basic model and remove, with various techniques, the excess parts.
It's a little long to explain, and now I'm busy, if someone else doesn't, I'll try to describe it later.
I note that I learned to do so by following the tips I found on this forum in a discussion a few years ago where a specific mini tutorial was published.

Okay, clear.
but the result must be good.
