A primitive called disk is a round plane with a certain radius and orientation

To create a Disk in the Main Menu select New Entity - > Primitives - > Disk

There are 3 algorithms to create a Disk in 3D space.
The Result of each operation will be a GEOM_Object (face).

Firstly, you can create a Disk at the origin of coordinates defining its radius and selecting the orientation of its axis with radio buttons (OXY, OYZ or OZX).This means that the Disk will lie in "OXY", "OYZ" or "OZX" plane correspondingly.
TUI Command: geompy.MakeDiskR(Radius, Orientation)
Arguments: Name + 2 values (Dimensions at origin: radius and orientation).

Secondly, you can define a Disk by a Center Point, a Vector defining the normal of a circle and a Radius.
TUI Command: geompy.MakeDiskPntVecR(Point, Vector, Radius)
Arguments: Name + 1 vertex (for the center) + 1 edge (for the direction) + Radius.

Finally, you can define a Disk by three Points that lie on its boundary.
TUI Command: geompy.MakeDiskThreePnt(Point1, Point2, Point3)
Arguments: Name + 3 points which will form the disk.

Example:

Our TUI Scripts provide you with useful examples of creating Primitives.
