# Point option in Rapidform XOR

Selection – If you select entities, the application show each entity’s name.
l Definition – You can create one reference point on the specified position.

l Extract– You can extract an average reference point from selected entities.

 Entity can be; Mesh, Region, Poly – Faces, Poly – Vertices, Ref. Polyline, 2D Curve, 3D Curve, Body Edge, Body Face Remove Outlier– If you select None, no outlier remove option will be used. If you select N*Sigma, you need to input N value into the box on the right. The fitting will be done by excluding fitting data whose error is bigger than N times of the standard deviation. If you select Ratio, you need to input a ratio value into the box on the right. The fitting begins with sorting the fitting data according to the error. Then only the data fall into the ratio will be used in the fitting. If you select Absolute Distance, you need to input a distance value into the box on the right. The fitting will be done by excluding the fitting data outside of this distance. If you select Sampling Ratio, the fitting will be done using fitting data sampled according to the specified value.

Use Only Effective Data – Effective data means sampled data and outlier removed data. If checked, only the effective data will be used in the fitting.

l Find Circle Center– You can extract an average reference point from selected entities.

 Entity can be; Mesh, Region, Poly – Faces, Poly – Vertices, Ref. Polyline, 2D Curve, 3D Curve, Body Edge, Body Face Fitting Type– If Fitted is selected, the reference point will be created by doing standard best-fit on the vertices. If Min Boundary is selected, among many reference points that pass the vertices inside the fitting zone, the one that parallels to the best-fit one and is most distant to it along its negative direction will be the reference points. If Max Boundary is selected, among many reference points that pass the vertices, the one that parallels to the best-fit one and is most distant to it along its positive direction will be the reference point. Remove Outlier– If you select None, no outlier remove option will be used. If you select N*Sigma, you need to input N value into the box on the right. The fitting will be done by excluding fitting data whose error is bigger than N times of the standard deviation. If you select Ratio, you need to input a ratio value into the box on the right. The fitting begins with sorting the fitting data according to the error. Then only the data fall into the ratio will be used in the fitting. If you select Absolute Distance, you need to input a distance value into the box on the right. The fitting will be done by excluding the fitting data outside of this distance. If you select Sampling Ratio, the fitting will be done using fitting data sampled according to the specified value.

Project on Plane– If you check this option, center point will be projected on selected plane.

Fix Radius – You can fix radius of cylinder. This can be reference to find cylinder axis.

Circularity – You can select solid edge, circle or arc.

User Defined – You can specify radius of circle.

l Find Slot Center– You can extract an average reference point from selected entities.

 Entity can be; Mesh, Region, Poly – Faces, Poly – Vertices, Ref. Polyline, 2D Curve, 3D Curve, Body Edge, Body Face l Find Rectangle Center– You can extract an average reference point from selected entities.

 Entity can be; Mesh, Region, Poly – Faces, Poly – Vertices, Ref. Polyline, 2D Curve, 3D Curve, Body Edge, Body Face l Find Polygon Center– You can extract an average reference point from selected entities.

 Entity can be; Mesh, Region, Poly – Faces, Poly – Vertices, Ref. Polyline, 2D Curve, 3D Curve, Body Edge, Body Face Rounded Corner– If you want to find rounded corner polygon, check this option.

Num. Of Edges– Specify a number of edges of polygon.

l Find Sphere Center– You can extract an average reference point from selected entities.

 Entity can be; Mesh, Region, Poly – Faces, Poly – Vertices, Ref. Polyline, 2D Curve, 3D Curve, Body Edge, Body Face l Projection – You can project a point onto selected entity.

 Point can be; Ref.Point, Curve Point, Body Vertex, Picked Point Entity can be; Any Entity except Poly – Faces and Poly – Vertices l Pick Multiple Points – You can create reference point by picking one or more points.

 Point can be; Ref.Point, Curve Point, Body Vertex, Picked Point, Spherical Region / Face, Circular 2D Sketch / Body Edge, Arc 2D Sketch / Body Edge

l N Division– You can create several reference points dividing a picked entity into several sections equally. You need to select only curve(s) or a vector and mesh.

 Curve can be; 2D Curve, 3D Curve, Body Edge Vector can be; Ref.Vector Mesh can be; Mesh, Region, Poly – Faces, Poly – Vertices

a) Uniform – Specify Number that you want to create. b) Offset – Specify Number and Distance that you want to create. l Between 2 Points – You can create a point between two points. You have to specify Ratio to decide position between two points. Point can be; Ref.Point, Curve Point, Body Vertex, Picked Point, Spherical Region / Face, Circular 2D Sketch / Body Edge, Arc 2D Sketch / Body Edge l Intersect 2 Lines– You can create reference point from the intersection of two reference vectors.

 Curve can be; Ref.Vector, 2D Curve, 3D Curve, Body Edge l Intersect Line and Face– You can create reference point from the intersection of a curve and face. You need to select reference vector or edge and reference plane or face.

 Curve can be; Ref.Vector, 2D Curve, 3D Curve, Body Edgy Face can be; Ref.Plane, 2D Sketch, Body Face l Intersect 3 Planes– You can create reference point from the intersection of three selected planes. You need to select reference planes or planar faces.

 Plane can be; Ref.Plane, 2D Sketch, Planar Body Face, Planar Region Check Orthogonal – If you check this option, the application creates a point only when 3 planes are orthogonal.
