A Sample Best Fit Alignment Graphical Analysis

This graphical analysis of the 3D Best Fit alignment displays this information in the Report window:

- Header - This contains various values used in the Best Fit alignment: Method, Standard Deviation, Mean, Translation offsets, Rotation offsets, Max iterations, Iterations.

- Vertical Axis - This shows the amount of deviation after the alignment.

- Horizontal Axis - This displays the IDs of the points used in the alignment.

### Quick Start: Align Toolbar

Quick Start Align toolbar

The Align toolbar allows you to create alignments from specific feature types by using these procedures.

Icon | Description | Quick Start Procedure
| Plane, Line, Line alignment | Select or measure a Plane to level to, and click Next. Select or measure a Line to rotate to, and click Next. Select or measure a second Line. The origin is created by translating the part to the two lines. Click Finish to insert the alignment.
| Plane, Line, Circle alignment | Select or measure a Plane to level to, and click Next. Select or measure a Line to rotate to, and click Next. Select or measure a Circle. The circle's center, projected onto the line is where PC-DMIS will set the alignment's origin. Click Finish to insert the alignment.
| Plane, Circle, Circle alignment | Select or measure a Plane to level to, and click Next. Select or measure the first Circle feature. Click Next. Select or measure the second Circle feature. PC-DMIS rotates the alignment to the line created from the centers of the two circles. It then uses the first circle's center, to set the alignment's origin. Click Finish to insert the alignment.
| Plane, Line, Point alignment | Select or measure a Plane to level to, and click Next. Select or measure a Line to rotate to. Click Next. Select or measure a Point for the alignment's origin. Click Finish to insert the alignment.
| Cylinder, Line, Point alignment | Select or measure a Cylinder, and click Next. Select or measure a Line. Click Next. Select or measure a Point. PC-DMIS levels the alignment to the surface where you clicked the point, rotates the alignment to the line, and sets its XY origin in the center of the cylinder. Click Finish to insert the alignment.
| Six Points Best Fit alignment | Follow the on-screen prompts to select or measure six points. A typical procedure would be to measure three points on the top surface to level to the Z Axis. Measure two points on the front surface to rotate to the X Axis. Then measure one point to define the origin for the Y axis. Click Finish. This will establish the correct origin for the alignment. PC-DMIS inserts the Best Fit 3D Alignment. Following execution, PC-DMIS will display a 3D Alignment Best Fit Graphical Analysis in the Report window.
