Mathmatical Relations Between Two Parts

Hello,
I'm new to SolidWorks comming from Pro/E.
In Pro it was possible to create a relation between two parts.
dxx=dyy:#

The mathmatical relation in SW is dxx=d##@FEATURE
Can this be modified in some way to point to another model?
If so, how?

TIA

If you want to relate two parts the most straightforward way is
through an assembly.

 

I have looked this post time and time again and I still have no idea what
you are trying to do. Maybe I just have a mental block, but I don't have a
clue. Would you please try to rephrase your question? I don't understand
the dxx, etc.

I'm still trying to figure out if either he's a victim of practical joke by
his co-workers who may have changed the guys sig and post from name, or if
he's serious with that....

A "from" posting of "I.M. Agamon" (I am a gay man) and a sig of "Dixon Cox"
(well, you can sound that one out yourself...)

 

Sorry, dyy=dxx@FEATURE (poor math notation).
y & x are numbers that correspond to the dimension numbers. Think
y=f(x)
dyy is the target dimension and dxx is the 'dependent variable'. This
method of dimmesional referrencing was picked up through my exposure
to Pro/E.

 

Are you currious?

 

What is a good online source, or help file seach parameter for
pointers?

 

My aim is to relate a single dimension / feature size on one part to
another dimension / feature size on another part.
The dimension / feature sizes are not co-planer, so a sketch edge
selection is difficult.
This is entirely possible in Pro/E.

 

Actually the help in SW should be all you need:

Equations
Creates mathematical relations between model dimensions, using
dimension names as variables. When using equations in an assembly, you
can set equations between parts, between a part and a sub-assembly,
with mating dimensions, and so forth.

What this means in practice is that to relate two components (parts)
in an assembly you double click the feature in the first part to show
its dimensions and select one of the dimensions. Then from the Tools
menu pick equations and pick add. That dimension should be
automatically placed in the equation editor. Then double click a
feature in the second component and highlight its dimensions and click
on the one you want in the equation. Then complete the equation.

In order for this to work both the parts and the assembly have to be
loaded in memory.

 

Thanks! This is what I was looking for.

The same holds true in Pro, to some extent. If the referenced model
is not in memory upon regen the dimension holds the last known value
as static. Only if you edit the relation will the dimension be
changed.

Thanks much again.

Sorry, no - to each their own. I was merely thinking that you were the
victim of a prank - apparently not. Just that most people, gay or not,
would post on a CAD newsgroup signing a name of "dicks-n-cocks" and expect
to get taken seriously.

But hey, you go with that if it works for you.

PS - Friendly advice ..."currious" is spelled "curious" - Your not going to
get any action from those that are "curious", if you appear stupid as well.

 

Ok, maybe I see.

Here is what I tried that I think you are desiring, and it worked.

I created an assy with two different parts, then inserted a new equation
like this: "D1@"="D1@". The result of
this is that if I change the length of part1, then after a rebuild, the
length of part2 changes to match it. You can create the equation in the
equation editor by clicking on the dimensions - you don't have to type it
all in.

In reality, my last name IS Cox. My mother's mother's maiden name was
Dixon. Not quite a practical joke, but when life hands you lemons...

Spelling is a weak point of mine. It's made even more when typing in
a cold room.

 

Wow! Yes! It's the format that I also need. I haven't had a chance
to experiment, but I'm assuming the method TOP gave will result in the
same format. Thanks people (never assume it's all males).

P.S. /, now we all know your a homophobe. The others looked past the
name thing and only tried so see my dilemma (checked spelling) and
give clear advice.

Sorry. In my excitement, I was a bit hasty. You confirmed that TOP's
technique results in the same format.

umm - actually, no.. at no time did I criticize your lifestyle, call you
names or such. I even stated, I believe 'to each his own' & 'whatever works
for you'. My first posting was simply to determine if you had been a
victim of an office prank, as small practical jokes are performed here on a
routine basis. It keeps the camaraderie here high and relieves the stress,
and everyone gets a good laugh including the victim. .(the last one I got
caught on was the old "light film of grease on the receiver of my phone"
gag..). That said, I was merely calling your attention to it - which, was
apparently un-necessary.... to which you replied with a snotty, arrogant
"are you currious" when you could have just simply stated "no, it's
correct - Are you able to help with my question?". Don't get so defensive.
Coming from a background in the performing arts for years, where one simply
can not be a "homophobe", I find your accusation is based on ignorance.
Glad you got your answer to you question and that you were helped out. TOP
and Wayne are some of the best you'll find on here. That said, I'll end
this discussion on this subject with a "Have a nice day, back to Solidworks
please" as this is becoming OT.
