Dragger:AxisRotate does not update GetModelCFrame

Feature Requests Studio Features
#1

When I rotate a model using a Dragger object, I would like it to also update the model’s CFrame so that its size corresponds to its orientation when I draw a box around it.

repro:

#2

GetModelCFrame is deprecated. Therefore I would not expect there will be any fix for this.

#3

How the hell are you supposed to draw a bounding box around the Model then?

It’s outrageous. We’ve never been able to get an answer as to why it was deprecated. I’ve already clarified that PrimaryPart is not a replacement, and there’s nothing else that comes even close to replacing it.

#5

You can’t get the bounding box of a model without using GetModelSize and GetModelCFrame.

#6

Actually I’m pretty sure GetExtentsSize is the same thing as GetModelSize.

You could go through the corners of each part and find the min/max for each dimension

Yes, but compare:

function getModelCenter(model)	
	local function recurse(root,callback)
		for i,v in pairs(root:GetChildren()) do
			callback(i,v)
		
			if #v:GetChildren() > 0 then
				recurse(v,callback)
			end
		end
	end
	
	local minX,maxX,minY,maxY,minZ,maxZ
	recurse(model, function(_,v)
		if v:IsA("BasePart") then
			if not minX then
				minX = math.min(v.CFrame * v.Size.X/2, v.CFrame * -v.Size.X/2)
				maxX = math.max(v.CFrame * v.Size.X/2, v.CFrame * -v.Size.X/2)
				minY = math.min(v.CFrame * v.Size.Y/2, v.CFrame * -v.Size.Y/2)
				maxY = math.max(v.CFrame * v.Size.Y/2, v.CFrame * -v.Size.Y/2)
				minZ = math.min(v.CFrame * v.Size.Z/2, v.CFrame * -v.Size.Z/2)
				maxZ = math.max(v.CFrame * v.Size.Z/2, v.CFrame * -v.Size.Z/2)
			else
				minX = math.min(minX, v.CFrame * v.Size.X/2, v.CFrame * -v.Size.X/2)
				maxX = math.max(maxX, v.CFrame * v.Size.X/2, v.CFrame * -v.Size.X/2)
				minY = math.min(minY, v.CFrame * v.Size.Y/2, v.CFrame * -v.Size.Y/2)
				maxY = math.max(maxY, v.CFrame * v.Size.Y/2, v.CFrame * -v.Size.Y/2)
				minZ = math.min(minZ, v.CFrame * v.Size.Z/2, v.CFrame * -v.Size.Z/2)
				maxZ = math.max(maxZ, v.CFrame * v.Size.Z/2, v.CFrame * -v.Size.Z/2)
			end
			
		end
	end)
	
	return Vector3.new((minX+maxX)/2, (minY+maxY)/2, (minZ+maxZ)/2)
end

local center = getModelCenter(workspace.Model)

with

local center = workspace.Model:GetModelCFrame()

The getModelCenter code above doesn’t even take into account rotation – that’d be a whole different ballgame. You’d have to find the alignment most parts are pointing towards, and that’d take a lot of work. GetModelCFrame does it all for you in one predefined function.

what about unions
