Do step files have material in them?

[-niels-]

I opened 2 different step files with notepad and it contains the following:

I'm guessing this comes from iProperties, so i'm inclined to say step files contain material info.

Hi!

I believe the step files would have the appearance (Color), but not the material info.
When converting to Inventor, You have to reapply the material to have the physical properties available.

The short answer is Yes.

Err, maybe...  All I am getting is name and Density outside of Inventor.

But when I open the STEP in Inventor I get all of the Material Properties.

Use 214 or 242.

Unfortunately not all CAD software can pick up the Material information...

And of course - as mentioned previously Material (properties) and Appearances are two different things.

And of course - you can do your own simple experiment within Inventor and with other software opening the STEP file.

I guess I should have matched up the Units in my test, but you get the idea - you can run a test.

Hi! Yes, I believe material styles are always supported in the STEP format itself. Inventor started supporting material styles in STEP translation in 2022 or so.

Many thanks!
