how to measure height without measuring tape

Tip: When you measure from an end point inference and create a guide, SketchUp creates a guide point, as shown in the figure.

(Optional) To move your guide line a precise distance from the starting point, type a number and unit and then press Enter.

(See Adding Text to a Model for information about labeling distances in your model.) In the following figure, the guidelines mark the distance 3 feet from the interior walls. If you pressed Ctrl in the preceding step, a guide line appears as a dashed line that reaches into infinite 3D space (at least within your model). The distance from the start point appears in the Measurements box.

Click at the ending point of your measurement.

A plus sign appears next to your Tape Measure cursor ( ).

(Optional) To create a guide line, press Ctrl (Microsoft Windows) or Option (macOS).

The Measurements box dynamically displays the length of your measuring tape.

The up arrow locks the blue axis, the left arrow locks the green axis, and the right arrow locks the red axis.

Press and hold a directional button while measuring to lock an axis.

In the figure, you see measuring tape aligned to the red axis.

The measuring tape line changes color to match an axis colors when it is parallel to any axis.
