A tool for sizing a workspace includes a first link with a link body and a tool element. The tool includes a second link connected to the first link, where the second link is capable of rotation or translation with respect to the first link, and where the first link and the second link are selectively securable relative to each other. The tool includes a third link connected to the second link, where the third link is capable of rotation or translation with respect to the second link, and where the second link and the third link are selectively securable relative to each other.
