Continuing on @john_drivenupthewall exemple:
- I have made some logs unique
- Then scaled them back to form one side of the opening
- Then used the move tool to make a copy on the other side, but when I try to push/pull, it’s the log’s right side that gets adjusted on both side.
- So what I do after is scale the right side about its center (holding CTRL) with -1 as scale factor, thus inverting the direction of the right side and make the adjustment of the opening symmetrical
As @Gully_Foyle said, the more information you share on your problem, the more precise the answer will be as there’s always so many ways to skin a cat
