Weight and inertia properties after Union trim
Weight and inertia properties after Union trim
(OP)
Hi,
I used a union trim feature in part design. I've two bodies, body.1 and partbody which contains union trim feature using body.1 as trim surface.
After trim union, Body.1 is hidden and I have on partbody the result I want; now I've some doubts about inertia properties. If I measure inertia properties of the whole part, they include properties of hidden part too and then body.1.
Is there a way to not include hidden parts in weight/inertia measurement?
Thanks
Pierluigi

RE: Weight and inertia properties after Union trim
I just repeated the steps in your original post whith V5R20, and I believe you are getting the correct results.
Remember, you are joining the two bodies together when you do a UNION TRIM, the measuring the inertia of the PartBody should give you the results of the resulting solid shape.
Measuring the inertia of a Body, will give you results of that Body only.
When you did the UNION TRIM, did you remove or keep some portion of the Body.1 ?
RE: Weight and inertia properties after Union trim
I know that the measuring the inertia of the partbody give me the result I want, that is the weight of the union trim feature result. But the measuring of the Part will be influenced by all bodies; I'm asking whether it is a way to measure a Product ignoring some bodies in the Part included in the Product.
For now, I can reach this result only as suggested by ferdo or rather selecting each body in my product and then apply inertia measurement. But it is not so friendly if i have a complex product with many parts.
