Questions using Mirror and Array to make a halway

Hello and thank you to start.
Im following along with a tutorial about making a spacey style hallway that looks pretty neat. At one point I was supposed to scale on the x axis to 0 to make sure a couple different sections were all at the same point and avoid gaps/overlaps. I didnt have any gaps before but I sure do now, trying to stretch or scale this has not worked out because it just moves the whole set making the gaps larger. My first question is, How can I fix this/avoid this in the future?


Seconds, I am also going along and making a different hallway of my own design while I am doing this tutorial i’ve got the basic shape done and have mirrored and array’ed it once to create the shape I want but now I want to cut what i’ve got into a simple shape that I can use to repeat over and over without it overlapping like it did the first time which caused some problems with the large checkered panel I made, the one in the middle now is flat because there are extra faces in there. Does anyone have any hints as to where I can cut this so that it can repeat smoothly and otherwise how would I do that. It also seems to be mirroring weirdly the X mirror mirror’s it on Z for some reason and the other ones are wrong too.


When you scale you scale based on the pivot point. Ensure you are using the correct type of pivot and it is located in the correct place.
If you are following a tutorial ensure you do what the tutorial tells you rather than what you think the tutorial is telling you.

ok sorry i didnt realize I could upload my files here. I figured out the second thing but the first one is still a problem.

any time i try to move the edges I adjusted it stretches the entire thing making the gap bigger.

You have to select all edges that will form the joint between the sections, then scale them to 0. You only selected the roof.


awesome thanks, cant believe I messed that up that selection and it caused all that.
