In BricsCAD you can navigate through a 3D model using the mouse and keyboard shortcuts.
In perspective mode you can walk inside the 3D model. In isometric mode you can only zoom in very close, but not go inside.

Zoom in / out. The incremental change in zoom with each mouse-wheel action is controlled through the Zoom Factor variable (ZOOMFACTOR). Default = 60. Values between 3 and 100 are accepted. When zooming in the incremental step decreases gradually allowing to focus on a particularly detail easily. In a 3D model the entity under the cursor has the zoom focus. The ZOOMWHEEL system variable controls the zoom direction:
