Description

Mirror symmetry mode for right-angled structural panels of the Making History expansion does not mirror part rotation properly, i.e. similar to triangular lifting surfaces. Instead the part rotation seems to be set according to radial symmetry mode, as shown in the attached images. This issue exists in all versions since the release of Making History.

This behaviour might be intended. If it is, consider this post feedback to possibly change it, since the current behaviour clashes with expectations established by other parts.

#1 Updated by Dunbaratu 8 months ago

I can confirm I have this same problem, and have had it since Making History first came out. The default orientation and mirroring of these parts makes them nearly useless for their intended purpose, seeing as how the only way to make them orient properly is to attach them one at a time and manually try to make them symmetrical by eye, which doesn't really work either.

  • Version changed from 1.6.0 to 1.6.1

Update:

Issue still exists in 1.6.1

  • Status changed from New to Confirmed
  • % Done changed from 0 to 10
  • Platform Linux added

Ran into this myself with some recent craft building.

To place a part in mirror symmetry, the editor needs to rotate the mirrored part so that its plane of symmetry is the reflection of the part being placed, that reflection being done in the mirror plane of the ((great)grand)parent part. Somehow, the editor needs to know the plane of symmetry of the part being placed.
There is no obvious indication of the symmetry plane in the configuration files. Surface-attachable from the core game have their node_attach point in their plane of symmetry, and the local y-axis in their plane of symmetry.

If we patch the configuration files as attached, so that KSP rotates the models of these parts to put their plane of symmetry in the x-y plane (like wing parts) then the behavior in the editor is much better. With branches of several parts connected by their nodes, however, the editor still fails to make mirror symmetry. Surface attaching works. (Radial symmetry always works.)

The attached patch changes the starting orientation of these parts, so it breaks existing craft files that use them, because the craft file stores the rotation of parts from their starting orientation to that used in the craft.
