scaling an assembly?

fightingtorque

I have an assembly - it is a logo/ badge consisting of several letters and a backing.  I want to bring this into a new part I am designing but I need to alter the size and aspect ratio to fit.  I could transform all the individual components and then rebuild it, but there is quite a lot of work in creating the assembly (each letter is positioned via 3 planar mates) so I would like to be able to bring that assembly into a part studio and transform it as a whole, is that possible?   
Ideally I would also like to perform some other mods to it (make the top curved by passing a curved "extrude remove" over it) so it would be best to have it in a part studio.  The individual letters were not sketched up in the current layout
Thanks,
Gav

Yes - create an in-context part studio and 'transform/copy' each of the parts into the part studio.
Transform also supports uniform and non uniform scaling as well as the moving of parts.

That said, modifying the letters before they are put into the assembly may be the easier way. 
Hard to say without being able to see the document.

I meant - if you share the document, 5 guys will fall over themselves to do it for you! 
(it will take 5 minutes )

Thanks.  It's here:  https://cad.onshape.com/documents/efbc8ac4efd8a15655539507/w/8f99d4e428d73d56f10c6871/e/9b32cfa75b42581d675cc177      

So the assembly of the letters into the backing pieces predates the component is now sat on.  If the letters and their backing could be scaled to fit the space for them, that is good.  If there was a way that it could be like that and in a part studio, that's also great / even better.

Thank you - I am in a couple of meetings this morning - if no one beats me to it (likely) I will look a little later

@fightingtorque You've posted a link to a read only file, so we can't help.

Please will you post to a public doc as per this https://forum.onshape.com/discussion/9107/forum-post-checklist

@philip_thomas I tried a bunch of ways for searching for this document via the search in "my onshape" and was unable to find it.  Are you using the Amazon algorithm?  You know the one where you type "M6 bolt" and it shows you a picture of an elephant you might like to buy...

Cheers,

Hi Owen, I've set it to public now.
thanks for looking!

@fightingtorque - something like this?

Created using in-context editing, transform and boolean.

Nice job Neil

Here's my effort.

Same as Neil's (blatant copy of his work) but with some custom feature script measurement variables to make it nice and parametric should the original part change size, and mullerage in height and width.

I had to rotate the part for the non uniform scale to be happy in x and y as that works off the document x/y/z orientation, that the part wasn't originally aligned to so that is a bit of a bodge.

Hopefully that gives you some more options.

That's perfect, thanks!
  So I don't understand how you made the steps that brought the badge and letters into the existing part studio, generating those little arrows next to the transform command?

NeilCooke

Right-click the base part in the assembly and select edit in context - that will ghost the other parts over it, then you can use transform/copy in place and boolean to effectively create them in the same part/part studio.

Thanks, got it!

I am back - looks like 2 people already fixed it for you - also, thank you for the TWEET

That's a nice looking part.

You caught my eye with the above sentence, why do you need 3 planar mates? Sounds like something we did in past with traditional cads. I would use 1 fastened mate with offset for each letter - or if  it's just one piece, do it completely in part studio resulting a single part that can be then easily scaled. 
If you wan't to keep letters separated, use derive to add them to frame.

ps. This community is purely awesome.

I am trying to insert an assembly (Engine) to another assembly (go kart) , but the engine is too large to fit in the engine bay, and i need to apply a scale factor to the assembly, including standard content instances, there are a lot of bolts, screws, nuts, and washers in an engine, and it would be a pain to edit every single one in the engines source document.  and no, I can not change the scale of the kart because this was all designed together to fit certain parameters, and the engine size is the result of a mistake.  Does anyone know a way to do this?

bruce_williams

to understand - you want to scale the engine assembly, correct?

If so, you should be able to follow philip_thomas original advice:

Yes - create an in-context part studio and 'transform/copy' each of the parts into the part studio.
Transform also supports uniform and non uniform scaling as well as the moving of parts.
