At the left side of the interface, various components of JT file are displayed in a tree structure along with their details. One good feature of this free JT Viewer is that it lets you view different components of a JT file individually. This means that you can select a particular component of a JT model and view it freely. You can also hide/unhide different components of a model to view only selected components at once. This feature truly helps in analyzing a 3D JT model easily. It even lets you take Snapshots of the whole model or separate components.

You can get Isometric, Top, Negative Isometric, Left, Front, Right, Bottom, and Perspective View of a JT model with this free software. Even the hidden and featured lines of a model can be viewed here.
