To create an \b Arc in the <b>Main Menu</b> select <b>New Entity - >
|
|
Basic - > Arc</b>
|
|
|
|
\n There are 2 algorithms to create an \b Arc in the 3D space.
|
|
\n The \b Result of each operation will be a GEOM_Object (edge).
|
|
|
|
\n Firstly, you can define an \b Arc by three \b Points that lie on it,
|
|
where Point1 is the starting point, Point2 is a middle point of the
|
|
arc and Point3 is the ending point of the arc.
|
|
\n <b>TUI Command:</b> <em>geompy.MakeArc(Point1, Point2, Point3)</em>
|
|
\n <b>Arguments:</b> Name + 3 vertices.
|

|
|
|
|
\n Secondly, you can define an \b Arc by \b Center, \b Start and \b End
|
|
points. The arc is built from the \b Start point to the \b End point. The
|
|
radius of the arc is defined by the distance between the \b Center point
|
|
and the \b Start point. The \b End point defines the angle of the arc. If
|
|
the distance between the \b Center point and the \b End point is not equal
|
|
to the radius, the arc will be built anyway.
|
|
\n \b Reverse radio button allows to change the direction of the arc.
|
|
\n <b>TUI Command:</b> <em>geompy.MakeArcCenter(Center Point, Start
|
|
Point, End Point, boolean Sense)</em>
|
|
\n <b>Arguments:</b> Name + 3 vertices + Boolean.

|
Finally, it is possible to create an <b>Arc of Ellipse</b>, which is also done by three points:
|
|
the Arguments <b>Point 1</b>, <b>Point 2</b> and the <b>Center Point</b>. The arc is built on the Ellipse that
|
|
lies in the plane defined by the three points, with the center in the <b>Center point</b>.
|
|
The major radius of the Ellipse is defined by the distance between the <b>Center Point</b> and
|
|
the most remote Argument point. The minor radius is defined by the shortest distance between the
|
|
other Argument point and the major radius.
|
|
\n <b>TUI Command:</b> <em>geompy.MakeArcOfEllipse(Center Point, First Point, Second Point)</em>
|
|
\n <b>Arguments:</b> Name + 3 vertices.
