cosmetic weight of fillet

[lu79lu]

Good morning to all,
possible that with creo and also with the old proe can not subtract the weight of the thread created with a cosmetic?
If I want real weight we put on a screw, do I have to shape the real thread? I feel like a waste of time. .
you could create a weight parameter of the cosmetic to remove to the total weight..but I have no idea how to do it. .
Does anyone help me or have any further info? Thank you.

Bye!
If I had this need, I would calculate the value of the parameter "playing" with the thread diameters (tables).
or I didn't understand your problem.

the problem is that the weight of the fillet cosmetic is not removed from the total weight. If I make a dia10mm pin and then I apply a fillet cosmetic, the weight does not change!

by removing the volume defined by cosmetics you would still have a wrong weight.

you in fact, create should remove the right weight according to the m of the thread and to the pitch

only by curiosity, can I know why you have this need?

 

[lu79lu]

because I need to have the real weight of the assemblies without having to remove all threads all the time. also the gram for the assemblies I have to do is important.

Well, if precision is gram order, I see it hard. unless specific software I believe that no other cad can help you (I have no certainty of course).

it came to mind that if you are sure to use all threaded holes that you realize, you just remove the volume (and then the weight) of the thread of the holes themselves, so when the screw is assembled compensates for everything. Obviously the thing could only work on a few processes (it should avoid a substantial amount of work) and on components of the same material (steel screw on aluminum piece and you are already out of road).
the problem of the material you could by-pass it by doing the same kind of subtraction both on the holes and on the screws, but using the average diameter (between hazel and nominal of the thread), but it is still a bump not recently, and above all, for those that are my knowledge, I do not know how "automatizable".

 

[lu79lu]

I have an excell sheet to know the weight of the threads according to the material, diameter and pitch etc., and I systematically correct the total weight at the table (and I do many). possible that a program of the reach of creo does not give you the possibility of 'automatizing'? I think other cads have done it for a long time. .

 

[tartufon80]

if we talk about automating "cree does things that you humans...". :wink:

In my opinion you must distinguish two types of problems: the correct weight calculation you look for, and their recognition on the cad.
at this point bring us the examples of other cads, so let's see how they do.
