HOW TO MEASURE A 2D FILE?
CST CAD Navigator provides two measuring tools to measure 2D files: Distance and Polyline Length.
Using the Distance tool, you can get the distance between two points.
Using the Polyline Length tool, you can get the length of a polyline part, its total length, or area.

Open the Tools
panel

types of snaps

HOW TO GET DIMENSIONS OF A 3D MODEL?
CST CAD Navigator provides three measuring tools to get dimensions of 3D models: Distance, Edge, and Distance
between edges/circles.
Using the Distance tool, you can get the distance between two points, between a point and surface, between twoparallel surfaces.
Using the Edge tool, you can get the length of an edge and the radius of a circle or a circular arc.
Using the Distance between edges/circles tool, you can get the distance between two parallel edges or between twocircle centers.

HOW TO CHANGE THE MEASURING UNITS?
You can change the measuring units in the Measurement settings section. Set the original units of a drawing/3D model(units in which it was created) and the units in which you want the measurement results to be displayed.

Set the units in theMeasurement settings section

Open the Tools panel andclick Measurement

HOW TO GET THE DISTANCE BETWEEN TWO POINTS?
Activate the Distance tool, then click to specify the first and the second points on a 3D model. The result will be shownin Measurement panel on the left and on a 3D model itself.

HOW TO CREATE A SECTION VIEW OF A MODEL?
CST CAD Navigator has a dynamic section tool. With its help, you may create a section view of a 3D model and see
its hidden elements. Sections do not modify geometry and are fully customizable.
Click the Add plane button
Creates a section in one of thedefault planes: YZ, XZ, XY

HOW TO ADJUST A SECTION PLANE’S POSITION?
To adjust a section plane’s position, move the sliders or specify the coordinates of the central point in the X, Y, Z fields.

Reverses the direction ofthe selected plane
