so i try to mirror a perfectly working sketch or a cutout of the same exact sketch to a parallel or coincident plane, but it gives this annoying and random error again ?
lolā¦ now i want to add some more features to a sketch, but why does it delete all of the new features from the side that it should be copied from, not the empty side copied to ?? O__O
Definitely need pics or video to understand what you are referring to.
Youtube is your friend when it comes to understand the modeling concept in SE.
There are tons of useful tutorials out there (youtube).
I think its worth spending some hours on it instead of just ābrute forceā different things to get a grip about how it all connects together.
