Encountered a couple of mistakes during this build and thought I'd share what was found and their solution.
The first is fixing a bad pivot. In the example shown, I'm not sure how it got that way, but it was mirrored from right to left in this particular case (not the usual practice).
As shown, the transform reset (on the object only) cured the error.
The second was a distorted shape when rotating the part. In the second example, the aileron PR was copied to make the flap PR.
The problem was that the PR had a link to the control horn, and deleting the link before making a new copy fixed it.
In preparing this help note, performing a local rotation with a parenting link present shows the same error.
Having said that, when copying or mirroring parts it is a good practice to:
1. Remove all links.
2. Perform the copy/mirror on one part at a time.
For example, if the ailerons and wing are both mirrored, the copied aileron might have some weird pivoting.
Now the transform reset may work on that pivot error, but it is usually rather easy to recopy/remirror from the single, unlinked source part.
Others with more experience please feel free to add your comments/corrections.
These were just some recently solved errors that are offered as help to other custom content creators.
