Example: Positioning a part by matching points

In this example, you will position part 4 by matching three points. The first pair of points (1 and 1') will lie directly on each other. The second pair of points (2 and 2') will determine a line on each part and these lines will be positioned directly on each other. And the third pair of points (3 and 3') will determine a surface on each part. These surfaces will lie on each other.

1. Click Structure and then, in the Part & Assembly group, click the arrow next to Position.

2. Click Dynamic. The Position dialog box opens.

3. Click part 4. Creo Elements/Direct Modeling displays the positioning options.

4. Click Other and select Match 3 Points.

5. Click point 1 on the part to be moved.

6. Click point 1' on the fixed part. Creo Elements/Direct Modeling uses the first pair of points to specify the two origins. The move point will be positioned so it lies on the fixed point.

7. Click point 2 on the part to be moved.

8. Click point 2' on the fixed part. Creo Elements/Direct Modeling uses the second pair of points to define two imaginary lines. One line connects the two points on the part to be moved. The other line connects the two points on the fixed part. These lines will be positioned so they lie on each other.

9. Click point 3 on the part to be moved.

10. Click point 3' on the fixed part. Creo Elements/Direct Modeling uses the third pair of points to define two imaginary surfaces. The three move points define a plane which will lie on the plane defined by the three fixed points.

11. You can now continue using the positioning options or click to complete the operation.
