• Ref. Geometry >> Create >> Plane >> Pick Vector & Point command adds a reference plane by selecting( picking ) a reference vector and a point or a reference point.
• The selected reference vector and the point are placed on the reference plane to be added.

Step   

Execute Ref. Geometry >> Create >> Plane >> Pick Vector & Point command as follows:

1. Select Ref. Geometry >> Create >> Plane >> Pick Vector & Point from the menu or click the corresponding icon from the Reference toolbar.

2. Select a reference vector to be normal of plane.

3. Select a point on a shell. distance from Ref.Vector to Ref.Point will be U-vector of Ref.Plane.

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

• 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.
