Assembly physical properties

Good day.

When I'm drawing a skeleton sketch, and then make an assembly by creating a component. my drawing properties does not go troight to the assembly so i have to manually redo all the properties like making it steel and recheck the masses, how can i make it to go trough to the assembly? Do i have to go check my settings or does anyone maybe have advice please?

HI!

IProperties from a part, and iProperties from the assembly are different things.
When in Drawing, it depends on what you are documenting: the assembly or the part.
Tell us more about your issue.

Hi William,

Inventor assembly (iam file) itself does not have the concept of material style (except Weldment assembly). An assembly is like a wrapper encompassing individual parts with the material style.

Please share an example that exhibits the issue. Forum experts can help take a further look.

Many thanks!

Hi you guys, thank you for replying.

Ok i'm busy with a design and in my design I have set my physical to a selected steel, but when I take it over to a standard assembly the properties are lost.

Here are the examples of what is happening, do you suggest that i must rather use weldment assembly?

No, i don't think turning the assembly into weldment assembly will solve your issue.

What do you mean by properties are lost? iProperties? Materials? Appearance?

Can yo post the parts, or a complete print screen?

Tip:

Try this: Set the material in the part, save it and reset material appearence in assembly.

I think there may be a bit of terminology problem here. It looks to me as if you are creating an assembly using the Master Modeling technique, in which you model the components as separate solid bodies in a master model (what you refer to as "skeleton") part, then use Make Components to turn them into an assembly.

If, as I read your post, the problem you are seeing is that the parts in your assembly are not Steel as your master model is, that is to be expected. The assembly components are derived from the master model, but unless they are sheet metal and linked to the master sheet metal rule, the material is not linked. The material must be assigned in the individual components, where you also assign other iProperties such as part number, description, stock number, etc. The individual components are also what you create drawings of for fabrication.

You can make this a bit less tedious by doing most of those edits in the assembly's BOM table.

My normal practice is to leave the material in my master model as Generic and make the individual solid bodies a wide variety of garish colors so they are easily distinguished while modeling. Then assign materials in individual derived parts (along with the associated appearance) so the assembly looks reasonably realistic and physical properties such as mass are properly calculated.

Hope that helps,

Thank you for the advice. I will try it that way.
