I have an assembly in which a component should not be considered in the calculation of the group mass. How can I tell swx to exclude from the calculation all the occurrences of that component in the calculation of physical properties?
 
Bye to all,

if I don't remember badly the envelope has this function (has no mass)
and that at the limit you can consider it by popping some flags in its properties.

I didn't think about it.
not having solidworks underhand do not know if a file already created can be considered as envelope, I would say yes...but I go to memory.

for hunting, if you explain to us to great lines your needs we can better help you.

the problem I have is this (always files arrived from other designers): I have to calculate the weight of a conveyor belt but excluding from the account the products to be processed and found on the tape. I could erase them temporarily, but many of these are nested in sub-axioms, and anyway I would like to have in the table the "net" weight of the machine, but that in the table itself see these products to give the idea of how the machine works.

idea "balzana"::
to those products of which you do not want to compute the weight, as material tries to assign the air. .

is not a very attractive idea for a rigorous engineer (:biggrin: ), if those products were then reused in other assemblies where instead the physical prosperity count??? (Let's move from the particular case to the general :smile: ).

I did a quick search also on the American forum but did not find much on the topic....
 
Let us summarize:
sol.1) suspend the components and use that conf. for the separate and calculating weight.
sol.2) envelope
sol.3) give specific air weight to the components you would like to exclude from the total weight calculation
sol.4) in the disitint excludes them and therefore in the total calculation are not calculated, if you calculate the weight from the bom.

1) I think it's the simplest and most linear, even if it would create problems in the table, not being able to have at the same time the right weight in the paper mill and the products in sight.

2) I don't know what I see studying it

3) I do not like for the reason mentioned above

4) This requires some work but you can explore.

If you select the component, it is highlighted in the bom and you tell them to exclude it or hide it.. I don't have solidworks to tell you more, but sailing in the bom is not difficult.
 
other solution: hide them and save the display status, instead of calculating the mass property of the axieme before performing the calculation do a selection window. being hidden will remain excluded from selection and therefore not weighed. I didn't try but it should go.

should be exact, in fact in the window opening analyzing the mass, there is the option to enable or not the calculation of the hidden components.

But when you make the table or see the weight "net" or see the products, it's still a little remedied.

strange that the cad lacks this important function.
 
For me, given the hunting needs, the best solution is:
sol.4) in the properties of the component excludes it from the disitint and therefore in the total calculation is not calculated.

This comes from the fact that it always generates a table and inserts all the info.
 
I don't know can help,
but I in our studies, where I need to represent fluid passages as solid, but without calculating the weight, I am using configurations.
that is, in those components that could be recalled in db or displayed in the table, but of which I do not want to make the weight, I create a fictitious configuration, e.g. with name massacre, to which I associate mass nothing (it can be done by forcing the mass properties and choosing to do it only for the selected configurations), then I configuro in the axieme (or in a specific configuration of the axieme) the component loading precisely.
in the paper mill
$prpsheet:"mass"
and I make sure that the first view of the tree is the one with the set-up in which the piece is mass zero.
for my purposes for now works.

I saw that if you want to work only at the level of configurations together, you can also simply create configurations where the components not to "weight" are suspended, then when you go to the table make sure that the reference view to recall the mass parameter points to the configuration without the elements not to be computed, while the bom make it of the complete configuration.

in this case you just have to set between the file properties the definition of the mass between the configuration specific ones (if not on the table will always call the default mass).

are attempts.. .

Bye to all,
After the intervention with the reporting of the envelope it seemed right to insert some extra explanation.

definition. (I try)
the envelope must be understood as the environment surrounding your project. does not weigh but creates physical limits.

applicability:
is used in axiemi and is used to support existing objects without these weighting on the current porphyry.
example. wall where I am modeling an object that rests on us.:tongue:

limits (up to version 2011):
1) you can use/create an envelope only from parts (multi body or not)
solution for assemblies. I'll take a set and save it as a part.
2) an enveloped part cannot return as a normal part.


use:
in the assemblies its weight is always zero and you can not even change.
the same object inserted as part has the possibility to have excluded the weight or not.

faq.
"I've inserted a part as an envelope and then I find that I need it instead"
solution (border line): I overlap the same part as normal, I hide it managing its weight.....

table.
the envelope is never shown by default. you have to select the display option (and maybe to respect its use change the line style).

The envelope never appears in the bom by definition.

in the zip I put a test for everything I wrote.

Good job
dancer
