• Measure >> Distance >> Point / Point >> Along Line command measures the length of the straight line which connects two points.

Step   

Execute Measure >> Distance >> Point / Point >> Along Line command as follows:

1. Select Measure >> Distance >> Point / Point >> Along Line from the menu or click the icon from the Measure toolbar.

2. Select two points in any order. ( See Selecting point ) 

During picking points,  User can select point entity on RMB menu as below fig.

 

Point : Any point on polygon face

Vertex : Scanned point

Ref.Point : User made Ref.Point 

Point On Surface : any point on NURBS surface

Point On Curve : any point on NURBS Curve

3. The result appears on the lower left side of the workspace window as follows.

Point 1 and Point 2 are coordinates of two selected points respectively.

Distance is the linear distance between two points.

Displacement is the displacement between the two points, that is, vector Point 2 - Point 1.

• When select two points, they do not need to belong to the same shell.

• Point on Surface option cannot be applied to surfaces without mesh or if rendering never been executed once. Because picking point algorithm uses rendering information. So Point on Surface option can be applied to TRUE COLOR display mode with rendering information only.
