How to do I make a part fit on a slanted roof?

Hi, I need help with trying to get a part to fit onto a slanted roof. Here’s a screenshot to show my problem.

As you can see I want the the part to come on the corner wedge. I tried using the select tool but that didn’t work.

Also, I realize the question is stupid. I’m just new to Roblox development.

Just move the part and Rotate it!

No worries, nice to see that you’re new and exploring ROBLOX studio. :slight_smile:

Simply click on the part, click the rotate tool and adjust until it gets to the slant, then expand the block to your desire.

Tried that - just made it more worse.

Go to model, and set the “move part” or “rotate part” numbers from 45º to 5º and start moving it until it’s orientated to the grade you want it to be.

I tried that but it isn’t what I’m looking for. As in, the results are not what I’m looking for.

I tried that and it almost worked. The problem is that the part now goes into the corner wedge. I need it to be straight but slanted.

This typically works for me, but I’m not sure if it’s an actual Studio setting or if it does it for everyone.

Have you tried selecting and holding that part and dragging it onto the slant?

Ye I did try it but it doesn’t seem to work for me. I’m assuming I might be doing it wrong.

@Musketfall As u can see from this:

I selected and dragged it but it didn’t work.

Are you putting it on the actually angled part by holding it and not the Studio drag tool?

What do you mean by that? I clicked on that part and then dragged it to the corner wedge.

Edit: Figured out what you meant. I used the Roblox studio drag tool.

Ahh alright, spent the past few minutes trying to figure out how to clip it for you since I’m bad at explaining things. Glad it works.

As in I tried but it still didn’t work. Sorry that I didn’t make it clear.
Starting to assume I’m doing something wrong.

I assume you made the house with unions- here is what I would do.

  1. Select the union. Separate the union.
  2. Take the negated part (that formed the upper edge of the roof,) and duplicate it with Control + D. (Or ⌘ if you’re a Mac user)
  3. Re-union one of the negated parts with the rest of the house.
  4. Take the remaining negated part, un-negate the part, and then adjust it however you like using the resize/move tool.

Hope this helps you, this is what I personally do to make parts line up.

I made the house without unions. Apparently, if you use the select tool the part automatically aligns but it didn’t work in this case. Although, the union idea is interesting but isn’t there any other way to do it?


Thought I should bring up a screenshot to show you.

Just use the model brush plugin, thats what I do, it auto orients to curves like wedges so just make the single part the thing youre brushing then place it on the wedge, then just adjust the X and Y axis so its not wonky and boom, I just it for quick roofs n detailing on wedges

Could you send a link for it? i

Go into the union’s properties → Look for something called “Collision Fidelity,” → Choose PreciseConvex.


Does this help?

Go to file > beta features and find something that goes along the lines of “studio draggers.”

I’ve got it enabled but what else should I do?

You should be able to drag the part on the slope now.
