Measure (only EX edition)

measure

Measure command provides the following operations.

Length

A length of a line (or a polyline) is displayed by mouseclicking. Creation of a polyline can be finished by mouseclicking the right button.

Click a start point for measuring,   Click one by one,   A length of a polyline is displayed.

When [Pt] or [Ln] is active in the Edit Option, you can snap the measuring position to a vertex or a line. It is useful for measuring the distance between vertices.

A snapping is available in the measure_lengthLength mode and the measure_angleAngle mode.

Angle

An angle is displayed by mouseclicking three times on an object.

Click the first point,   Click the second point,   Click the third point, and an angle is displayed.

You can move a point in a polyline for an angle measurement by mousedragging it.

An angle is displayed.   Move a vertex of a polygon,   The angle is updated.

measure_lengthLength and measure_thickThickness can also move the point.

Perimeter

When you click any point on the object, it measure the object's perimeter including the point.

Auto
It detects the direction of the perimeter from the direction of clicked edge automatically.
YZ
It measures the perimeter parallel to the YZ plane.
XZ
It measures the perimeter parallel to the XZ plane.
XY
It measures the perimeter parallel to the XY plane.
Arb.
Click two points and specify the line, measure the perimeter along the line.
Click two points   Measure along the line

Thick

It displays a thick when you mouseclick on an object. The direction measuring thickness is selected from a normal direction or an eye direction.

Normal
It displays a thickness to the normal direction at the mouseclicked position.
Eye
It displays a thickness to the eye direction at the mouseclicked position.
Colorize thickness
It visualizes a thickness as a vertex color. A display range of thickness can be adjusted by a slider. The color is applied [Color map] of [Configuration > Display].

Object

It displays the size of the bounding box including a whole object by mouseclicking the object.

Click on the object.   Siize of a bounding box is displayed.

The displayed size for the bounding box is also updated when the object is modified.

Change 3D / 2D

This item is available only when measuring [Length] or [Angle].

3D
It measures the distance between two or more points in three-dimensional space.
2D
It measures the distance between two or more points on the two-dimensionally projected plane. Even if you rotate the camera view, it doesn't move the measuring position on the two-dimensionally projected plane.
*2D mode is available when [Perspective] is [Ortho] in View header.
Even if you rotate the camera view, it doesn't move the measuring position

Show area

If you check this item, it measures the area including the specified multiple points.
This item is available only when measuring [Length] or [Perimeter].

In [Length], it measures the area of a triangle composed of clicked three points. If you click four or more points, the polygon is divided into multiple triangles and calculate the area.

When you specify four or more points in [3D] mode, polygons may not be constructed on the same plane. The area of tis polygon is inaccurate. (Different values are calculated depending on the method of division into triangles.)
Don't use this value as accurate.

When "(Non-plane)" is displayed, the value is not accurate.

In [Perimeter], it measures the area of cross section on the object.

Clear

It erases all measures.

Each measure can be erased by mouseclicking the measure_deleteicon.
