Why won't it work and how do I fix it?

You have to use CFrame.new() for a coordinate frame, not Vector3.new(). CFrame.new(X, Y, Z)

✓ Accepted answer

when you call the CreateRay function, you put Character as the parameter. The problem with that is that you never defined what Character was, so the ray won't ignore anything.

Either define what Character is at the beginning or use Player.Character instead of Character.

Hope this helped!

EDIT:

You're calling the MoveTo method on what I assume is a single part. Well, the MoveTo method acts the same way that changing the position of a part does: If the new position is within a part, the part will be placed on that X and Z points, but the Y will be the lowest clear area. Basically, the part will be placed above whatever blocks are blocking it.

To fix that issue, change the CFrame of the block instead of moving the Model by using the MoveTo method, like so:

Part.CFrame = CFrame.new(Pos + Vector3.new(0, Part.Size.y / 2, 0)) --I'm adding half the part's Y Size because then the part will be above the ground rather in halfway into the ground

NOTE: Pos is the 2nd argument you get from the FindPartOnRay(Ray) method. Use that instead of Mouse.Hit.p because that way the part will be positioned exactly where the ray hits and you can ignore multiple objects using the FindPartOnRayWithIgnoreList(Ray, Table) method.

NOTE 2: The table in the FindPartOnRayWithIgnoreList() method has to be filled with the objects that you want to ignore, for example:

local IgnoreTable = {
	Player.Character;
	Part;
}

EDIT 2:

Yes, it would be best to use the SetPrimaryPartCFrame(Cf) method on the model. Just be aware that the model needs to have a primary part though. You can do that through the script, like so:

Model.PrimaryPart = Model.Part

I'm moving a model with multiple parts so will I use the "SetPrimaryPartCFrame" method or do I just get all of the children?

I got a error I can't put a vector3 to a coordinate Frame,how do I fix it?
