To Delete Points from a Scan Set

Vérification de fabrications > VERIFY > Working with Scan Sets > To Delete Points from a Scan Set

1. Choose Delete Pnts from the SCAN SET menu. The SEL SCAN menu appears, listing all the active scan sets in the assembly. If you place the pointer on one of the listed scan sets, a bounding box of the same color appears on the scan set in the assembly.

2. Select one of the scan sets. The FILTER PnTS menu appears with the following options:

◦ Reduce—Reduces the number of points in the scan set according to defined criteria

◦ Remove—Permanently removes points from the scan set according to defined criteria

◦ Whole Set—Applies the point reduction to the whole set of scan points

◦ Pick Box—Creates a box after you pick two points on the scan set to act as diagonal corners of a rectangular box. The points contained in the box are deleted

◦ Near Plane—Do one of the following:

▪ Select an assembly datum plane.

▪ Pick three points to define a plane. The plane is then displayed on the assembly.

▪ Enter a tolerance around the plane. Points in the resultant 3D space are deleted.

◦ Half Space—Select an assembly datum plane or pick three points to define a plane. The plane is displayed on the assembly. Enter a tolerance around the plane. An arrow appears on the assembly, normal to the plane. The DEL DIR menu also appears. Click Flip to flip the arrow. Click OK to accept the direction shown. The system then removes all the points on the arrow side of the plane plus all the points that are within the specified tolerance on the other side of the plane.

▪ Done—Deletes the selected points and return to the SCAN SET menu.

▪ Quit—Ignores the selections made and returns to the SCAN SET menu.

3. Use the menu commands, in any order, to delete as many sets of points as you want. As you define each set, the system highlights it in red.

4. When you have finished, click Done to return to the SCAN SET menu. The system then removes the points in the selected areas.

You can also use pick boxes to exclude sets of points from the fit features. You can also export a transformed scan set to a file and create the coordinates that you want. You can use this file within Creo Parametric or export it to third-party software for further processing.
