# Measure
Under the *Analyse* icon, click *Measure.* By default, Object mode is active.
Select two entities in the model. The shortest distance between these entities will be displayed.
Enable the *Vertical (Z)* mode in the command center. Now the shortest vertical distance between the two selected entities will be displayed.
Select another entity. This new entity will now be checked against the entity you selected *last*. You can not have more than two entities selected during this procedure, so the first selected entity will automatically be unselected.
It is also possible to measure the shortest distance between *sub*entities, i.e. faces, edges and vertices. To do this, enable [Deep Select](/documentation/qonic-application/basics/navigation-and-selection/selection-modes.md#deep-select) mode and click the faces, edges and/or vertices you want to measure the distance between. Your selection can be a mix of any of these (sub)entities.
Enabling the Angle option will display the angle between two planar faces, two linear edges or a face and an edge. This mode only works with faces and edges, so Deep Select will be automatically enabled.
Switching to Points mode allows you to click any point in your model and find the shortest distance between these points. Click more points to add this to the chain and find the respective distances as well as angles between two subsequent sets of points.
Click the XYZ option to break down these distances in their X, Y and Z components.
