I have a 3D shape in space and need to create its right-hand configuration but I cannot get it to mirror (sometimes it will translate it), or it won't even move it. It also will not let me mirror without a solidbody in the part. I have SW 2016 SP4.0
You should enter this as an idea in the Top Ten list. Submissions close tomorrow, the 15th so don't delay: SOLIDWORKS World 2017 Top Ten List
If you have trouble accessing the Top Ten area then reach out to Matthew Lorono or Richard Doyle.
This has been request for > a decade... seriously, I could mirror sketches in 3D >20yrs ago in other programs!...
So, do they really care about adding requested and NEEDED funcationality... or, do they care about $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$?
It is slightly frustrating that I have to ask the CNC programmer to mirror it in MasterCAM. I would like to not rely on him to help me finish my job.
Workaround is to make a surface and mirror that.
I see what your doing there. That would work but in my 3d sketch I have multiple closed patterns and not everything is flat or has a smooth contour. What surface feature should I try to get this?
Just about surface so long as you end up with edges that match your sketch curves will do. You can make planar surfaces from planar contours. Maybe fill surfaces for the odd potato chips?
It might take a couple steps for difficult geometry, e.g. make a sweep or make an extrude and then trim after.
I recommend using the "WhateverWorks" add-on.
how was this 3D sketch created?
Its from the customer via an IGS file. From there I have no idea how they created it. Maybe I need to go do some of my own scribling and see if I can mirror that?
Edit: This was unsuccessful. It mirrors the solid body but the sketch is simply a translate.
And have you tried 'Mirror Part'? you will have to add a small sold body like the assembly example above. But I assume these 3D splines nothing is going to just mirror with out surface/solid bodies?
I have attached a file to this reply. Let me know if its a perfect mirror for you. I cut the box in an irregular pattern to ensure I am mirroring LH/RH.
Mirror Part is a feature inside a part file

Go to Insert > Mirror Part
So, I kind of have a work around, but it is nasty......you have been warned!!! (I am using SW 2015 btw)
Add any solid body to the part (even a little cylinder off to the side, unless you already have one).
Add the part to a blank assembly, then mirror the part around the plane that you want.
Here is an example:
In this part, I created a quick 3D sketch that is a simple circle and added it to the blank assembly.
I selected mirror, selected the part and selected my mirror plane.
I made sure that I selected "create opposite hand version"
Selected create new files:
Then made sure that "absorbed sketches" and "unabsorbed sketches" are both selected:
Now I have something with the sketches mirrored.
Now you have a choice. You can open the new part, and break all the links if you want. You won't be able to modify the mirrored sketches, but you can use them for surface creation and whatnot.
I told you it would be nasty...
Nice. I played with this an hour or so ago, and tried to use the Mirror Component function, but didn't think of creating a body to make it work.
I have tried this with no success. Here is what happens when I do it, same way:
Its hard to see but I mirrored across the block's top plane and 1) its nowhere near the original object (16ft) and 2) if you rotate and move it, its the same, NOT a mirror. This isn't the first time I've had issues with it, also wouldn't do it in SW 14 or 15. I have tried different bodies, different planes, export igs/ import igs then mirror and many more...
