A stupid question...

OK. to preface this absurd question, I feel that I should say that the
company I work for will not send any of us in engineering to a course
on solidworks. This creates an interesting situation, wherin I have to
ask stupid questions.

That being said, It IS possible to extrude a hole through all parts of
an assembly(this I have done), and yet the cut does not translate to
the individual part when open on its own. It seems to me, that the
answer is very simple, and I just cant seem to find it on my own.

Likewise, it seems to me, that a cut should be able to be made in an
unfolded or flat state in sheet metal, and then fold back into its
finished form, with the cuts relative to the material instead of the
plane.

Like I said, im sure this is painfully simple, but i really could use
some help.

Thanks,
Cris

 

When created a cut extrude in an assy, the whole will not show up in
the individual parts UNLESS you are editing the parts "In Context" of
that assy. When editing In Context, you are basically editing the part
while the assy is open. When you do a assy cut extrude, the hole(s)
will show up when doing an assy drawing, which is what the assy cut
extrude is for.

Heres something that may help.

1. Do the assy cut extrude. After this is done, you will have the
hole(s) in all of the parts you want.
2. Next, edit each part that has the hole(s) "In context". When doing
so, use the command "Convert Entities" on the hole(s) desired. After
doing this, do a cut extrude on the part(s).
3. After you have the hole(s) you want, open each part and edit the
feature for that hole. You will see that feature is referencing the
assy, so you have 2 choices.
a) Delete the reference. After this, dimension the hole.
b) Keep the part referenced. In the early design phase, I usually
keep my parts referenced, but when the design is done, its best to
delete reference, and dimension the features in the part itself.

Hope this helps, and isnt very confusing

Post back if you need more help...

 

When you use a feature cut in an assy, it stays there as is - it doesn't
propogate back to the parts because it's not supposed to. Think of it this
way. You make some parts, you weld them together, and then you drill a hole
through several parts because you want to make sure the holes line up after
the welding. If the holes went back into the parts as you suggest, then the
piece part drawings would show a hole, and that would not be correct. Maybe
that's what you really want this time, but it's the wrong approach.

Instead, you have a few options.
1. Put the holes in each of the piece parts manually.
2. Put the hole in one of the piece parts, and then in the others with an
in-context relation to the first one.
3. Same as 3, only use a sketch in the assy to drive the holes in all the
parts.

When you put holes in a sheet metal part, there are many different ways to
accomplish it. Per your direct question, you need to do an unfold, put in
the holes, and then put in a refold. This will put the holes in the flat &
formed configs. Do some reading on sheet metal in the help - you'll find
some very good info.

Depending on the type of hole you want, maybe a hole wizard, "hole series"
may fit your needs. These show up in the assembly and the individual parts.
You can modify them to fit. See the "elp"area

"Help" It must be "Beer30"

Use the Hole Wizard Hole Series, as someone else said. It will put the
hole to each individual part

It depends what technique you're using for this. If you use the "base
flange" technique, you can put in an "unfold" feature, make the cut,
then put in a "fold" feature. If you're doing the "insert bends"
technique, you can put the cut between the "flatten bends" and "process
bends".

 

Couldnt get the hole wizard to cut through all parts either. not sure
what the problem is...it worked the same as extruding a cut through the
assembly. It showed up in the assembly, but not in individual parts.

Im just not a big fan of having the circles of different parts relate
to each other, it makes it a pain for another engineer to play with the
assembly later on, and not follow what ive done...but thanks for your
help so far. Im using SW 2004...BTW
