Parts weirdly placing themselves wrong

I’ve been getting into building again lately, and constantly encounter the same issue which I had months ago, parts are not perfectly aligned to each other. I have no idea what is causing this neither how to fix it. I am on 0.5, half a Stud for moving, and the difference seems to always be about 0.1.

You can set the moving to lower than 0.1.
Although, I don’t know why it does that.
EDIT: I didn’t understand the question, you just need to make the moving to about 0.1 and just move it with the tool

So, one thing you can do is use position in properties instead of dragging

That would be really painful to do, 0.5 Studs is good with the Baseplate, I am trying to build a whole facility and use Studs to measure perfect distances.

Thought about that too, however that would still take way too long, I will see if the position is slightly changed in the properties, and remove the error as far as possible, if not, I’d rather try to find another solution.

Sadly, I think setting it to 0.1 is the best way, because I don’t think it will work in any other way.

Are you moving more than one part at once (or any models/grouped parts)? Also, check the orientation. If you move diagonally, it changes the part’s position dramatically. Moving models/grouped parts after re-orientating them also have this effect.

It’s a grouped model, consisting of thee parts. This image shows a wall, the standard one I copy and paste is small, and I have made a row of 5 for that reason, to save time. Basically I do both, either just the grouped wall, or 5 of them at once, sometimes it does this, and sometimes it does not.

It’s because the grouped model has it’s own outer hitbox positioning. It’s bit annoying (especially with models which stick out - like have etchings but with parts) as it has slightly different size values, causing stuff like 0.01 positioning faults and clipping. The same goes for unions. While I don’t know how to fix this (sorry!), I think you can avoid it by only moving one of the models values (x, y or z) and not touching orientation. Like, if I have a 50 stud wide model, if I moved it 50 studs (increasing let’s say the x value by 50), from my experience, it doesn’t cause positioning changes. Though when I change another value (moving it up then left), it causes this tiny change (like 0.0001) and those slowly build it if I then duplicate the previously duplicated piece.

Also, if you didn’t know Ctrl+D duplicates something, so you don’t need to “copy and paste” and saves you moving stuff around.

Been playing around a little, I totally forgot about the duplicate option, so I tried that, and the issue didn’t occur again for the whole wall of that one room. However this doesn’t solve it yet, as I have the same problem with another grouped model, which is supposed to go above doors, finishing off the wall. The x, y, z part is way too time consuming in my opinion, so I will just go with luck, much appreciated.

On a quick note, 0.1 Studs is not it, tried to fix these errors with that, it’s more like half of 0.1.

I’m not entirely sure why it’s happening but it happens to me sometimes as well. I use ResizeAlign to fix it quickly though. It’s a great plugin and you can use it for a lot more than fixing those really small gaps that are usually a pain to fix.

This is some weird thing with how ROBLOX rotates Parts that it’s on a certain axis and doesn’t always work as expected. I recommend either changing the scale to about half of what you’re using so either 0.25 or 0.1.

To just get rid of this easier, I recommend Resize Align
