Mass Properties in IGES or STEP files?

ptc-354508 · ‎Jan 18, 2012

Does anyone have any insight on exporting IGES or STEP file assemblies that keep the mass properties with them. I have created IGES and STEP files and when I go to view the Mass Properties all of the densities have been reset to zero. Am I missing a step or a config setting somewhere? Thanks.

I actually tried individual parts & assemblies. All the information is still with the parts. If you have an example you can post it & I can open it to see.

Hi Mike

Two questions I would ask you

1. Have you tried with assembly with different densities?

2.While opening iges parts/asm was USE TEMPLATE activated?

When I creat parts from iges it contains density=1.00000 unless use template is selected

Yes, I have tried assemblies but I was not using templates. I did try the use template & I am having the same result as you. I don't know why that is.

Hi

As per my understanding

iges is a neutral format for transferring 3D dimensinal Data only

It does not contains parameters like mass properties

But while opening you can assign default template mass properties by clicking the use template option

This was my understanding. But I dont have any reference Data to Support.

(Please Correct me If I am Wrong)

Hello,

I think you are correct. Its never been an issue for me though. I use iges to send to customers. Sometimes they send to me to create or fix but I prefer to make my own models in PROE so I can have an adjustable model with a nice model tree.
