Is there a way to move an object you've used C-Frame on without it reverting?

I've been trying to build a model using C-Frame, and Roblox Studio tends to want to revert it before moving the object. Moving the object with the C-Frame tools is an inconvenience too.

You might be telling it to go to its start position, causing it to revert.

I don't know if I totally grasp your problem, but if I do, try calling

part.CFrame = part.CFrame +-*/ Vector3.new()
