Construction Struts in Symmetry Don't Connect Correctly When 2 Inline Parts are Facing Away/Towards Each Other

OS: Windows 10 | CPU: Intel(R) Core(TM) i7-10700 CPU @ 2.90GHz | GPU: NVIDIA GeForce RTX 2070 | RAM: 16GB

 

Problem:

Steps to Replicate:

1. Put one inline part
2. Put another inline part and rotate it in a way that it's "in mirror" with the other part
3. Use symmetry of 3 or above
4. Place struts between the two parts

Additional information:

• Both parts don't have to be the same (It just need to be rotated by 180° ("in mirror")):

Has done it right from the start. Very frustrating. Then again, what isn't.

first i always see if i cant tweek it, but if not i have to delete, then look for the extra struts that are left (4x will leave 3 after i hit backspace). so i can either delete all extras or just Half and then while having Sym set to either 2 or Mirror i set them

This is another bug:

Happens with fuel lines too. Probably uses the same mechanic.

[Suppise]

So that’s what causes this. Had this issue so many times lol

From what I've experienced, this especially happens when trying to connect struts to an adapter part which has slanted sides.

Maybe I made a change to the craft. I've got a two Hydrogen ball/swerv ship whereI flip a duplicate and join. Used to be able to strut directly  between them, then started seeing the twisty. It's possible I rearranged the coupling sequence and introduced the problem about the time 1.4 came out.

This problem there from the beginning version.

This can happen even with simple structures.

I think, this is due to the incorrect direction of its rotation when the surfaces are facing different directions.

so I must've twisted them the wrong way on a rebuild, that just happened to come in between patches. Thanks for the diagram, now I know what to look for.

(and they still need to fix it lol)

Had this since 1.2.

happens to me for different reasons, from large part count, differing angels, short connect runs,  just trying to mirror, or to *inverted parts.                                                                                                                                 (*game reads parts in one directions and can get criss crossed)        i get it with 4x or more. (i dont really do 3x strut)

first i always see if i cant tweek it, but if not i have to delete, then look for the extra struts that are left (4x will leave 3 after i hit backspace). so i can either delete all extras or just Half and then while having Sym set to either 2 or Mirror i set them

had a bit more to add

Perhaps I have made a significant alteration to the craft. I have developed a unique two Hydrogen ball/swerv ship, where I duplicate and merge them. Initially, I could easily connect them with a strut, but then I began to notice a peculiar twist. It is plausible that I inadvertently modified the coupling sequence, which subsequently caused the issue around the release of version 1.4.

This is still happening in 0.1.5.

When attaching struts to an above decoupler that is flipped upside-down using symmetry (using the 'w' key), the struts attached using symmetry will have seemingly inverted connections to the ones on the decoupler and base fuel tank.

@EchoNovemberDelter, merged your bug report.

[Chel]

+1 here. Was going to add struts under the impression it would just have a single one going between the four SRBs, result was spaghetti with them clipping through and ending outside the part unconnected.

Aircraft symmetry seems to be a work around, but that only applies to two parts at a time.

I have a video but unsure on how to submit to forum post, would just a pure bug report rather than reply be preferable?

Also in 0.2 and 0.2.1
