Pretty much, my problem is this: I was making an office build in Roblox Studio, and when I made a laptop for the office, I came to a problem: I made it too large. Whenever I try to make the model smaller, I can make it as large as I wish, but I cant shrink the model at all.

If the model is anchored, unanchor it and select it. Then size it the way you need.
It’s not anchored, I don’t know what else could be the problem.
In “model” uncheck Move
303030
Its not checked, and the problem is with scaling, not moving.
Ungroup it and unanchor then resize.
Try putting a primary part in a group that is big, maybe that will help. Else, use the properties to edit the size
I tested with unchecking “move” and its worked
You can change the scale manually in the part section
I tried that before I made the post and it didn’t work. I also thought it might have something to do with the 2 unions, but when I tested it out I had a different outcome.
If parts inside the model are at 0.05 scale, then you must resize all the other parts
I do have some parts that are of 0.05 scale, let me see if that works
Try using ModelResize, it might help you out.
I would check the constraints and the collisions in the home tab, uncheck both of those and try resizing it from there.
If that still doesn’t work then I highly suggest downloading the Model Resize plugin through studio. Also nice model hope this helps.
Hi I think easier way to resize model is use of this one plugin: https://www.roblox.com/library/143613186/Model-Resize-Plugin-2-1-DRAG-TO-RESIZE
it work like normal Roblox resize tool!
Thank you all for the ideas, I was able to fix this in post 9
