measured, by a simple line between points. You can use the Measure Options to choose how these are

displayed.

Note

It goes without saying that you must click on a point on an item to register a point - clicking on the

background will not register anything, but it is worth noting that you can snap to certain points on

items - see Section 16.3.1, “ Snapping ” for more details.

You can reset a measure command at any time by right clicking instead of left clicking in the main

navigation window. This will start the measure command again with no points registered, just as if

you had chosen a new measurement type.

Measuring between points on items

1. Ensure the Measure Tools control bar is displayed as outlined above.

2. To simply measure the distance between two points, choose the Point to Point measurement type

on the Measure Tools control bar and click on the start point and then the end point with the

left mouse button.

3. To lock the start point and then click on multiple different end points, choose the Point to Multiple

Points measurement type on the Measure Tools control bar and click on the start point. Every

other click after the start point will then register a new end point, but you can right click to reselect a

start point.

4. To measure the distance along a path or route, choose the Point Line measurement type on

the Measure Tools control bar and simply click on a series of points along the path. The Distance

will display the total distance along the path from the start point. Right clicking will enable you to

select a new start point.

5. To calculate the sum total of several point-to-point measurements, choose the Accumulate

measurement type on the Measure Tools control bar and click on start and end points

alternately. The Distance will show the sum of all point-to-point measurements since the first start

point. Right clicking will enable you to reset the distance to zero and restart the calculation.

6. To calculate an angle between two lines, choose the Measure Angle measurement type on the

Measure Tools control bar and click on a point on the first line, followed by the intersection of the

two lines, followed by a point on the second line. The Angle will show the angle between the three

points. Right clicking will enable you to select a new first point.

7. To calculate an area on a plane, choose the Measure Area measurement type on the Measure

Tools control bar and simply click on a series of points to describe the perimeter of the area you wish

to calculate. The Area will show the area of the perimeter described since the first point, as projected

onto the plane of the viewpoint. This means that all your points should lie on the same plane for your

area calculation to be perfectly accurate. Right clicking will enable you to select a new first point.
