    its not nearly as good as SW, the mirror there is with the mates, a huge time saver.

    why has this not been implemented?

    I guess it is a matter of logic. A mirrored part is not just another instance. It is a part in it's own right, and should therefore be created on the part studio level.

    I have been using a CAD sytem where parts could be mirrored on the assembly level. Looks nice at first glance, but since the mirrored part was just another instance there, the drawing of that part was logically referenced to the parent, that is: Not mirrored. Now guess how much money this has cost the company ...

    I've been using OS now at my dayjob for 3 years. I honestly remember only one time I wanted to mirror an assembly instance, but I figured a way around it. I guess what I'm saying is I know everyone is asking for it, but it just doesn't seem a big deal to me not to have it.

    Also for clarification, for those that want it, do you want "the same instance" to have its position mirrored in an assembly? Or, do you want an actual geometric mirror of an instance, resulting in a unique, second part?

    The first one can be accomplished today with just another mate of the same part in a new location within the asm, or a circular pattern (if the mate connector for the pattern is in the correct place). The second scenario is simply a mirror at the end of the tree inside the part studio.

    I guess I don't see the big deal.

    Would this be an option? In assembly select "Create Part Studio in context". When in the new part studio you will get the ghost images of the parts in the assembly, mirror these with a plane and then select the mirror parts to be inserted into assembly.

    In this link I created 2 parts in the part studio. I placed them in an assembly and grouped them. I then made a mate connector where the mirror would occur and selected this as my origin when selecting Create part studio in context icon.  In the new part studio is created I mirrored the ghost images of the parts and selected both part to be placed in assembly. If you make a change to the original parts , upon returning to the assembly you can update the context so the mirrored parts will be updated.

    Here is the link to the doc.


    Hope this helps

    Yes, this is one case where a part studio in context can be very convenient. I learned the allegedly mirrored parts are seldom precisely mirrored. We end up with them looking similar, but one having tabbed holes and one having countersunk clearance holes, or one having the negative and one a positive lip or the like. All this could be easily achieved in a part studio, and this also takes care of the mirror being correctly given a unique part number and entry in the BOM. One could even think of configuring e.g. the holes for left and right part, and so on.

    If nothing else, mirrored parts don't generally get left handed threaded holes.

    Even symmetric parts are often not 100% symmetric within themselves. The outside might be perfectly symmetric, and most of the inside is too, but there will be mounting bosses or ribs or whatever which are not symmetric.

    A mirrored part is not a part in its own right, if you're actually "just" mirroring a part. I'm working on has parts that are, quite literally, just flipped "upside down" Right vs Left. "Just create a new part studio bro" is not a great answer to this, as now I have to clean up the mess OS just made of the BOM.
