Resetting part orientation

[feral quiver]

I have a part in workspace that is randomly oriented, and all I want to do is place a block at the end of the part and reset its orientation to 0,0,0

This seems to be a difficult task for me.

Server script in ServerScriptService:

local function branch_offs(parent_branch, model)
    local end_of_branch = Instance.new("Part")
    end_of_branch.CFrame = parent_branch.CFrame * CFrame.new(0,parent_branch.Size.Y/2,0)
    end_of_branch.CFrame *= CFrame.Angles(0,0,0)
    end_of_branch.Size = Vector3.new(1,1,1)
    end_of_branch.Anchored = true
    
    end_of_branch.Parent = model
end

branch_offs(workspace.Part,workspace)

Would appreciate some help. Let me know if you need more information.

The block is successfully going to the end of the part, but it refuses to reset its orientation no matter what I do.

end_of_branch.CFrame = parent_branch.CFrame * CFrame.new(0,parent_branch.Size.Y/2,0) * CFrame.Angles(0,0,0) what is this doing

the *= is just adding another * on the end

if you want to set the cframe, you have to set the cframe, with =

I did that, but what it ends up doing is moving the part to the position 0,0,0 as well.

But I get what you mean, its just telling the part to rotate by 0 degrees in all directions with the *.

multiply is not strictly rotate

But if I'm only multplying by CFrame.Angles() it is only telling the part to rotate, correct?

what are you trying to do exactly

[feral quiver]

Place a part at the end of another randomly rotated part, with the new part at the end having no rotation at all.

I use CFrames to guide the new part to the end of the old one, but that incorporates the rotation of the old part, which I wish to remove.

Never mind, figured it out.

put an attachment positioned where you want and set cframe to that

or construct new cframe without rotation at the attachments position
