Vector command allows you to add reference vector.

1.

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

2.

Change method to Find Cylinder Axis.

3.

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

4.

Click OK button. XOR finds a center vector of cylinder region.

l Selection – If you select entities, XOR show each entity’s name.

l Definition – You can create one reference vector with specified position and direction.

a) Position & Direction – You can create one reference plane with specified position and normal.

         Position - Specifies the coordinates of the starting point of the to-be-created reference vector. You may directly input the coordinates into the X, Y, Z boxes or you may pick a point and its coordinates will be displayed inside the X, Y, Z boxes automatically.

         Direction - Specifies the direction of the reference vector.

b) Start & End – You can create one reference vector by connecting two specified points..

Start Position and End Position- Specifies the coordinates of the starting point and the ending point of the to-be-created reference vector. You may directly input the coordinates into the X, Y, Z boxes or pick a point and its coordinates will be displayed inside the X, Y, Z boxes automatically.

l Extract – You can extract reference vector from selected entity.
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.

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.

Project On Plane - Creates reference vector by projecting to a selected reference vector along the vector's normal direction.

l Find Slot Axis – You can find a slot axis form selected area of a mesh model.
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 Cylinder Axis – You can find a cylinder axis from selected area of a mesh model.
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).

       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 cylinder.

       Initial Axis - If you check this option, XOR search the most suitable normal of selected item.

Fix Axis - It is used to set the axis of reference vector using Vector or User Defined direction.

l Find Cone Axis – You can find a cylinder axis from selected area of a mesh model.
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 reference vector onto selected entity.
Selection Entities: (Ref. Vector) and ((Ref. Plane or 2D Sketch) and (Body Face)).

l Pick Multiple Point - You can create reference vector by picking multiple points.
Selection Entities: 2 *(Ref. Point or Curve Point or Body Vertex or Picked Point).

l Pick Point & Line – You can create reference vector by picking a point and selecting a line.
Selection Entities: ((Ref. Point or Curve Point or Body Vertex or Picked Point) and ((Ref. Vector and (2D Curve or 3D Curve or Body Edge)) or ((Ref. Plane or 2D Sketch) and (Body Face)))

l Intersect 2 Planes – You can create one reference vector from the intersection of two selected entities.
Selection Entities: 2 * ((Ref. Plane or 2D Sketch) and (Body Face))

l Average – You can create one reference vector by averaging several selected entities.
Selection Entities: 2 * (Ref. Vector and (2D Curve or 3D Curve or Body Edge)).

l Cross 2 Lines – You can create one reference vector by selecting 2 crossing lines.
Selection Entities: 2 * (Ref. Vector and (2D Curve or 3D Curve or Body Edge)).

l Revolving Axis – You can find revolving axis from selected area of mesh.
Selection Entities: N * (Mesh or region or Poly Faces or Poly Vertices).

l Extrusion Axis – You can find extrusion axis from selected area of a mesh model.
Selection Entities: N * (Mesh or region or Poly Faces or Poly Vertices).

l Pattern Revolving Axis – You can find a revolving axis made by pattern. You need to select two more regions.
Selection Entities: >=2 * (Mesh or region).

l Pattern Translation Axis – You can find a translation axis made by pattern. You need to select two more regions.
Selection Entities: >=2 * (Mesh or region).
