Question concerning mirroring

kurt_dorfner

Hello,

I´m beginner and excuse my bad english.

I have a question concerning mirroring.

I´m drawing a complex component for the Right-Hand-Side and need the same fort the Left-Hand-side, practical a Mirror. I don´t need to draw it for the left side again new, it´s a lot of work.

I did it with the command „Mirror“ and had two parts on the screen, the Right and the Left.

One Drawing should be separate for the right part and one drawing separate for the left part.

Therefore I erased from the two parts the right Component to have only the left Component and then to save it. But if I deleted the Right the Left disappeared too !!!!

How can I  eliminate the dependance. What can I do that I can produce a separate drawing for Left and Right ? It should be possible, but after a lot of hours a have no result.

Please help me. Thanks a lot in advance for a solution!!!

kind regards - Kurt

Hi @kurt_dorfner welcome to Onshape!

When you say "drawing" do you mean a 2D drawing or a 3D model? Onshape uses Part Studios where more than one part can be designed together (which is why you have two parts on screen). Do these 3D models need to be in separate windows? Probably not. When you create a 2D drawing (or if you are exporting just one part for 3D printing), you can select which part you want to draw (or export). It makes no difference that the parts are together in the Part Studio.

Does that make sense? If you REALLY want them in separate tabs (windows) you can use the Derived feature, but this is really not necessary.

it sounds like your mirror command adds geometry to the original body, check if the option in the mirror is "New" but not the "Add". If it doesn't help you would better post here a link to to the problematic document.

Thanks for the quick replay!  If I say "drawing" I mean a 3D-model. And if I used the mirror-command I used the option "New". Of course I would like to post a link to this dokument - but how I can do this??? In my old and simple 2D-CAD I have the possibility in the Mirror-Command to check a box "Duplicate", if I don´t check I get only the new mirrored Part. Maybe, for this what I need, the "Mirror-Command" is wrong, maybe an other Command would do what I need. Regards - Kurt

Just paste the URL here. 

You can keep both mirrored parts in the same Part Studio. It is not a problem. Use hide/show if you just want to view each one. When used in assemblies and drawings you select which one you want.

Concerning Link: the document called "Trichter_R" and should for everybody accessible

We can probably find that but in future please post the URL from the browser starting https://cad.onshape.com/documents/.... thanks!

@NeilCooke, the problem is I need to export the Model in STL and print this on 3D-Printer, I´m not sure if this woud work correct if I only hide the one part (maybe then I get 2 parts)

NeilCooke

Just right-click the part you want to export and select Export

Thanks a lot for all answeres ! I see, in OnShape it is not possible to make only a simple mirrored part, only with complicated ways (like "with the church around the cross). In Fusion 360, a part of the awful autodesk, it´s the same. Nobody need such? I don´t understand why, but it is so.....  kind regards - Kurt

Hi and welcome.I too need mirrored parts, but I'm not following you on the difficulty.  There is a great mirror command and it works with just a couple of clicks.  If you post the link to your doc as Neil says (just copy the address from the top of your browser and then past it into the forum post) then folks will jump in and help.

Also just an hour or so invested in the training media to get to grips with the terminology will make it much easier for us to help you with regards to phrasing the question.

A drawing is 2D representation of a finished part

A sketch is a 2D drawing used to generate a part via features.

A Part is a 3D object.

There is a 2D Mirror for Sketch Entities, and  Mirror feature for Parts or Faces Or features. 

So it's easy to offer incorrect advice if we misunderstand the question asked.  More info here:- click-me

Cheers and happy CAD-ing, Owen S

Hello Kurt,

I just made a copy of your document, and I see that you created your mirrored part, so I,am confused what the problem is.
When right-click on the part in the left colum, you can export the 3d file, or you can create a 2d drawing the part.
See screenshot

I know exactly what Kurt's problem is, as I am also struggling with this, as there is no 'easy & simple' solution, like just click the mirror part and decide there and then, to separate the two parts, or make them one part.

All he and I want is make a mirror of a part and separate it from the original… ie have two separate parts The mirroring is easy, but I still cannot get mine to separate, so to print it out, I select only that part and export and print it, but the original and mirrored part are still connected in the drawing…

You have to make new offset planes… mirror about a 'mate connector'… etc. Man this should be so much simpler and easier…

MDesign

When you use the "New" mirror it creates a new part. just a click of the part and a click of the plane to use for the mirror. Are you saying you want the program to just mirror the part at a random location of its own choosing?

MDesign

if you want a completely separate part just duplicate the part studio and mirror the part in the new studio. then you have 2 parts in separate document that can be edited without affecting the other.

Here's some samples showing the difference between 'new' and 'add in the mirror function. For any mirror that uses add the parts must be in contact or you will get new part. Hope this helps. Like others I recommend the learning center intro sections so we're all talking the same language(Onshape).

@kurt_dorfner - When you used the "mirror command", it creates a "multi-part" part studio, with two separate parts (if you selected "new"). The disappearing part is caused by "parent - child" relationships, and you need to understand how this works. As others have said, why are you deleting the parent part (right component)? Just leave it there.

In an assembly, you can "insert" only the left component if that's what you want - same goes for making 2d drawings. Assemblies and drawings are the environments where you are going to "use" the parts, the part studio is for building and editing only that one part (or however many parts are in the multi-part, part studio). Generally speaking - you do not use the part studio to make assemblies.

If you don't fully understand the subjects above that are in quotations, look them up in the help index - or better yet, take the free self-paced courses in the learning center, it is a great source for step by step instructions and information. Stay with it, we were all beginners once.

P.S. - I keep a notebook, that I write down the solutions to problems like these. It is very worn, because it gets a lot of use.
