Point command allows you to add reference point.

1.

Click  button on the Default toolbar, or click Insert > Ref.Geometry > point.

2.

Change method to Extract.

3.

Click Region in the Select Filter toolbar and select the region like below image.

4.

Click OK button. XOR extracts an average point from selected region.

l Selection – If you select entities, XOR 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 area of a mesh model. You need to select mesh, region, poly-face, poly-vertex, polyline, curve or face.
Selection Entities: N*(Mesh or Region or Poly Faces or Poly Vertices or Poly Line or 2D Curve or 3D Curve or Body Edge or 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 find a center point of circle from selected area of a mesh model. You need to select mesh, region, poly-face, poly-vertex, polyline, curve or face.
Selection Entities: N*(Mesh or Region or Poly Faces or Poly Vertices or Poly Line or 2D Curve or 3D Curve or Body Edge or Body Face).

Fitting Type - If Fitted is selected, the reference vector will be created by doing standard best-fit on the vertices. If Min Boundary is selected, among many reference vectors 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 vector. If Max Boundary is selected, among many reference vectors 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 vector.

       <Fitted>             <Min Boundary>        <Max Boundary>

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 find a center point of slot from selected area of a mesh model. You need to select mesh, region, poly-face, poly-vertex, polyline, curve or face.
Selection Entities: N*(Mesh or Region or Poly Faces or Poly Vertices or Poly Line or 2D Curve or 3D Curve or Body Edge or Body Face).

l Find Rectangle Center – You can find a center point of rectangle from selected area of a mesh model. You need to select mesh, region, poly-face, poly-vertex, polyline, curve or face.
Selection Entities: N*(Mesh or Region or Poly Faces or Poly Vertices or Poly Line or 2D Curve or 3D Curve or Body Edge or Body Face).

l Find Polygon Center – You can find a center point of rectangle from selected area of a mesh model. You need to select mesh, region, poly-face, poly-vertex, polyline, curve or face.
Selection Entities: N*(Mesh or Region or Poly Faces or Poly Vertices or Poly Line or 2D Curve or 3D Curve or Body Edge or 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 find a center point of sphere from selected area of a mesh model. You need to select mesh, region, poly-face, poly-vertex, polyline, curve or face.
Selection Entities: N*(Mesh or Region or Poly Faces or Poly Vertices or Poly Line or 2D Curve or 3D Curve or Body Edge or Body Face).

l Projection – You can project a point onto selected entity. You need to select point and reference plane, reference vector, reference coordinate or face.
Selection Entities: N*((ref. point or curve point or body vertex or picked point) and not(poly faces or poly vertices)).

l Pick Multiple Points – You can create reference point by multiple picking.
Selection Entities: N*(ref. point or curve point or body vertex or picked point).

l N Division – You can create several reference points dividing a picked entity into several sections equally and perpendicularly. You need to select edge or reference vector.
Selection Entities: N*(2D Curve, 3D Curve, Body Edge) or (Ref. Vector and N * (Mesh or Region or Poly Faces or 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.
Selection Entities: 2 * (Ref. Point or Curve Point or Body Vertex or Picked Point).

<Ratio: 0.2>          <Ratio: 0.5>           <Ratio: 0.8>

l Intersect 2 Lines– You can create reference point from the intersection of two reference vectors.

l Intersect 3 Planes – You can create reference point from the intersection of three selected reference planes. You need to select reference planes or planer faces.
Selection Entities: 3 * ((Ref. Plane or 2D Sketch) and (Body Face))

       Check Orthogonal – If you check this option, XOR creates a point only when 3 planes are orthogonal.
