Handling Handed parts

Handling Handed parts

Handling Handed parts

(OP)
Just wondering how others handle handed parts and assemblys in Solidworks; when it comes to things like naming them, making drawings for them and how they appear on the BOM?   

RE: Handling Handed parts

(OP)
Handed part = Right hand / left hand .... symmetrically opposite parts....

RE: Handling Handed parts

Mr. Koko - so far I have created the left hand part of my product on the left side of plane and then mirrored it around that to create the right hand part. Then I use the add suffix or prefix option to label it RH or LH.

I'm not sure if this is the best way of achieving handed parts, so I'm very interested to see how other people manage it.

Some times I have trouble achieving the desired orientation of the mirrored part, although this is likely to be caused by my inexperience more than anything else.

RE: Handling Handed parts

i've seen a couple methods for naming- adding R or L to the end of the part number, or adding -1 (for right) and -2 (for left).  

Usually i make a drawing for the right-hand part and add a note that says the left hand part is opposite.  

RE: Handling Handed parts

In the assy you can mirror the part. I would give them separate part numbers.
If they are complicated parts, I would link them and when updating one the other will update, but still a separate P/N.
Otherwise, I would do the same as Matt and model them separately.

Ok, how about this.  How do you guy handle quantities of handed parts ?  Lets say you need 2 rights and 3 lefts for some reason.... do you write the quantities right on the drawing or ... is there some custom automated software that does it .. or ?

RE: Handling Handed parts

Are you using the SW BOM? The BOM should populate the parts.
Curious, where does the term 'handed' parts come from?

RE: Handling Handed parts

It depends on handed parts for us.  If it is the same model, except with holes on opposite sides, then we use the config name of "LH" and "RH", So the part number on the drawing and BOM is ######-LH &######-RH.

If it is a mirror of the whole body itself, then I make a mirror in the assembly level, and give the mirrored part the next consecutive number following the original.

"Handed part?"

"Curious, where does the term 'handed' parts come from?"

Are you guys serious? You've never heard the term "handed part" before?
Left hand, right hand, opposite hand ---> handed.
What would be more logical? Bloody foreigners! rofl

cheers

RE: Handling Handed parts

Of course I have heard of "Left hand, right hand, opposite hand", but never heard anyone call it a "handed part". When I first read the post, I thought of maybe some manufacturing term, not a CAD term.

RE: Handling Handed parts

I think the phrase comes from common sense really.  Without discussing such parts with other people first I referred to them as handed parts, it just makes sense to me.

Does anyone have any simple assemblies that show how they have organised handed parts?  I would be interested to have a look!

RE: Handling Handed parts

(OP)
Just a kind of related question, does your part file name (ie xxxx.slprt) equal the part number that appears in a BOM?

RE: Handling Handed parts

Chris,
It is more of a manufacturing term then a CAD term. More specifcally a draughting term used in the UK ... at least it was when I were there.

cheers

RE: Handling Handed parts

mrkoko,
I would create a separate part number and detailed drawing for each handed part. At some future time you may need to manufacture just the LH part(s) without need of the other.

cheers

RE: Handling Handed parts

We use the same filename plus M (mirror)for suffix.  For example 12345.sldprt & 12345M.sldprt  That way we do not need to worry about interpretation of whether something is left or right.  You'd be surprised what people can waste time arguing about!  Any mirrored part following our definition has to be identical in every way except for the mirror.  We check this in API routines by comparing the weight within .1%.  If the weight is different it, must be different.  We make a drawing for the mirrored and nonmirrored part so that we can use each part where ever we want.  We do the same for mirrored assemblies.

RE: Handling Handed parts

Bradley,
I have actually seen a left handed adjustable wrench. The scroll worked in reverse.

cheers

RE: Handling Handed parts

Probably made in England. LOL!  CBL - I love many English things.  The cars, the beer, the humour & etc. Some English things are, well, just unusual.

I suppose you’ve seen the muffler bearing I had to go ask for as a youth?

RE: Handling Handed parts

I am a big fan of using the mirror part functionality in SolidWorks.  I then assign a XXXXXXX-001 and XXXXXXX-002 number to the left and right respectively.  As far as the parts list goes on the assembly.  I would have qty X of XXXXXXX-001 and qty Y of XXXXXXX-002

RE: Handling Handed parts

Talk about getting off the thread topic!  Oh well, it is Friday - have a great weekend guys

RE: Handling Handed parts

Back to the topic of mirrored parts.

I look forward to the day Solidworks successfully mirrors cosmetic threads. Every new release I check to see if there is progress, and every new release I've been disappointed.

At least it doesn't leave the threads hanging in space anymore!

RE: Handling Handed parts

Mirrored Cosmetic Thread works fine for me with SW08-SP3.

cheers

RE: Handling Handed parts

CBL,

Does the hole callout of a threaded hole in a mirrored part include the threads in 2008 SP3?

Eric

RE: Handling Handed parts

The Annotations' Hole Callout does not, but the HWs' Thread Callout does.

cheers
