join two solids to be able to collect them

[Federico3000]

hello to all, I am a novice in the use of solidworks and I have a question:

How come in sw some solids can join and others can not?
in my case (look photo) the solid above (i.e. the window) obtained with an extrusion joined with the main solid and therefore it was possible to collect it, while in regards to the underlying solid it was not possible, even selecting the item "join result in the function "base extrusion". What does it depend on?

I would say that it depends on the fact that you are working partly with solids and partly with surfaces. Obviously the extrusion of a solid does not join with the surface so you cannot make us fittings. sure from the only feature manager you do not understand which surfaces are and which solids compared to what you see in the screen

Thanks for the answer.

What could be the solution? However the second solid is obtained by extruding a sketch just like the first, because in the first it works but in the second no? the solid with which you must collect is the same in both cases...

 

[Federico3000]

I did other tests and noticed that both I use the solid function is that I use the sw surface function does not allow me to join the two parts.

the big solid do not think it is a solid, it is understood by the fact that the rectangular surface on the side window has the blue edge, it means that the solid is open.
if you actually have two solids. in the solids folder in the feature manager you have to find two solids, we do not see it from the image.
in case they were two solids it could be that the union of the two solids creates an invalid geometry, like a edge that ends up on a tangency or other similar things.
also known that the two solids are not matched together, did you match? Otherwise you can't collect a multi body.

Thanks for the answer.

If you have two surfaces that intersect you have to make a reciprocal cut to have a common edge to collect.
but did you check whether the larger circulating part in which that parallelepiped is a surface or a solid? otherwise we continue to reschedule advice without knowing what we are talking about.
If you had attached the file you would already get the soluzoine to your problem, so maybe attach it now that we do first and better.

All right now I try to attach the file.

 

[Federico3000]

here is the file

and of course you give us little and nothing. It's all a surface! ! !
above all ask for clarifications on a problem and place a file that that problem has no reason to have it missing the painting that protrudes.
and we are only at the 9th post....

Now I put the painting and put it back.

but also using the surfaces does not allow me to connect.

 

[Federico3000]

in what sense "is all a surface", I practically only worked with solid commands.

Forgive me for posting too many messages.

 

[Federico3000]

Thanks for everything, I solved alone, it was simply a problem related to the scale of the degrees.

Try to do a section in the part and see what I mean.
or look at the top feature manager and see how many solid bodies you have

He doesn't let you tell him why you ask him to do impossible operations. If you have two surfaces and trim them in a reciprocal way you are sure that the fittings you make them.

If it tells you that it is a surface it will mean that it is a surface. If in a solid do a face erase you become a surface, just to say one. However the surfaces are there because they are seen in the feature manager.

You'll have to read too many answers. . .

I would say at this point an explanation is you owe it to us. you should tell us how you solved and especially what "scale scale problem" meansI couldn't open your file because I presume it's done with a later version of mine but it was time to check it out. if you had compiled for benign the info of your profile you would have indicated version of swx and its service pack and I would not have put them to download the file and try to open it.

just to make everyone understand what you are talking about I attach a u image of the section and the feature managaer.
The solids you see are the so-called painting and a cylinder placed on the top. all the rest are surfaces

Cvd!

of beauty there is to say that these threads at least develop to the inverosimile the extrasensory capabilities:wink:

 

[MassiVonWeizen]

mike, you are lucky you have an old version and you have not seen how many functions (almost all form changes are made with extrusions instead of revolutions) and sketches (two sketches, equal, with a line that acts as axis to make two cuts in revolution) useless.
not to mention the underfinished sketches.

cvd!

look how it is reduced.. .
