Hello
In SW2020, I try to create a symmetrical component (with addition in a derived configuration) according to the right plane of the component (in X only), but I always end up with an inversion according to the face plane.
I just want the orientation of the piece to stay the same, just to symmetrical right and left without reversing head and ass, but nothing to do.
Is it yet another SW bug, a SW debilitation, or me who is stupid?
Result obtained, which I don't want:
Hello,
What options do you select here?
Exactly those of your image @Silver_Surfer
And obviously for the creation of a derived config you don't have the choice of the alternatives proposed by the buttons to the left of the " create " button
This is what I get with my piece. Would the result correspond (all geometry aside) to what you want to achieve?
Yes, that's what I would like. A "side " mirror.
In the first page of the property you select the right plan, I guess? Whether I choose the right shot or the front shot, the result doesn't change. I don't understand...
Can you show (screenshot) of your selected options and for all pages please?
(NB: the pink part is just a masked body)
But, even if the orientation of the created component seems correct in the assembly, in reality the face is turned upside down, and when we check the derived config we can see that the head goes to the ass:
Original:
Derivative:
This also forces us to reorient all the constraints already created in the asm...
I have the same result in terms of configuration with my part.
So I think it's a mathematical logic related to the normals of the planes. I may be wrong, but I feel like this is the only way to achieve the symmetry of the part without having to change the directions of the functions.
What would be interesting to test is if the constraints are maintained if before operating the symmetry, you name entities used for the constraints?
It could work: the following names for symmetric entities:
I know what you mean, it's an idea to remember. The thing is that in this case my constraints are aligned on plans. So I have to reverse the orientation of coincidence constraints.
And beyond that, that the orientation is not correct in the room itself particularly irritates me.
Well, if I understand correctly, if I want a real symmetry of the part according to X I have to use a symmetry function of all the bodies directly in the part and make a config of it...
Hmm, I think it's mostly a question of the laziness of the devs; If we can have all the alternatives in " no config " mode, or even with body symmetries, it's possible. They just set the face plane as the default plane of symmetry without giving us the option to change it.
For me, the answer is the second.
Or a bug that makes the config creation ignore the plan chosen on page 1... But since then it would have been corrected (or not, we're talking about SW here)...
Hello
For me you have to deselect the 'smart' thing of solidworks (in yellow) and switch to the good old manual that should work (the 4 manual orientations circled in blue, logically the one you want is the one I put in red).
Originally the dynamic aid was unleashed, but in the face of so much debility I had displayed it to be sure. These are only illustrations of what what we are flying over does, nothing intelligent or automatic. The worst thing is that the helper shows exactly the function in side mirror, but it applies a face mirror... of the SW in all its splendour 
Unfortunately what you propose is not suitable @froussel because I would like the alternative config in the same room. That's kind of the interest of configs it seems to me.
And my body symmetrization is not viable because it keeps the original bodies visible and adds as much. Not great.
For lack of anything better, I'm going to double the sketches, too bad...
You have to look in your tree (feature manager) if you don't have several symmetry folders in your symmetry config (one cancelling or modifying the other)
I had the 2020 for 3 years and never encountered this problem and yet I made many parts with this method. (derived config in the same room)
Of course not. I delete each " folder " and config with each new messed up attempt. I even reloaded the room without saving, just in case.
Or is it SW who is tired and needs a reboot...?
Yes in the assembly it appears correct, but it's only an illusion, look better at the orientation of the planes 
No, for me the planes remain the same and the symmetry is well realized by the chosen plane:
On the other hand, I insert the part in an empty assembly and I take the plan that interests me in the assembly where I inserted the part (maybe it changes?)
Is it thanks to you that we can make wishes? 
Hello;
I also (or poucenlairize 
) the symmetry from a new assembly with plans not from the 3D parts or components (Use those of the new assembly).
From what I see on your animation @sbadenis , the symmetry plane is always the front plane. Maybe I'm expressing myself badly 
Exactly the same result with the right-hand plane of the assembly as a reference.
Alas, no 
, the wishes are for shooting stars (meteors, or even debris). Otherwise I would have wished that SW would work as it should.
I didn't understand what you wanted, ok after checking yes the symmetry is indeed done systematically with respect to the front plane.
A hack solution would be to rename the front and right plane after the symmetry. (by having drawn the part in the sense that the plans will be good once renamed...
At the same time it has never bothered me in my assemblies where I insert the symmetrical component and often tell it by its plans by choosing the one I want.
If it can help illustrate the problem:
The back of a plane can be distinguished by its dark contours, from the face of a plane with light contours.
I have used this function very little but I have never had the problem until now either because, luckily, the symmetries happened to be on the front plane. But to be forced to build a room with the face on the right plane seems absurd to me... For me, the nose of a fuselage is the front, the face. So why would I draw it from the right on the front plane? Well I don't know about Dassault but it seems logical to me...
