Preprocessing Operations

This section introduces the following preliminary processing operations before machining:

Preprocess with One Click

This operation is used to preliminarily process objects with one click automatically.

To preprocess with one click, do the following:

Select the target objects.
To open Instant Pre-process dialog box, do one of the following:
- In common tool bar, click .
- In menu bar, click Object → Shape Pre-process → Instant Pre-process.
- In drawing window, right click and select Instant Pre-process.
Instant Pre-process dialog box pops up:
Check the target items and set values of parameters.

Simplify Polyline: reduce the number of extra control points on a polyline, so as to improve machining efficiency. A control point is a member of a set of points used to determine the shape of a curve.

Mark Mini-Circles: change cutting tiny circle into piercing.
Optional: Check Apply When Importing, the system processes the objects automatically according to the selections above after importing a toolpath file.

This operation is used to delete overlapping objects that are similar.

To delete overlapping objects, do the following:

Select the target objects.
Click Object → Shape Pre-process → Delete Overlaps. Delete Overlaps dialog box pops up.
Enter tolerance.

The system automatically deletes similar objects within the tolerance and saves one object.

This operation is used to delete self-overlapping lines on an object.

To delete self-overlapping lines, do the following:

Select the target lines.
Click Object → Shape Pre-process → Delete Selfoverlaps. Delete Self-overlaps dialog box pops up.
Enter tolerance.

The system automatically deletes self-overlapping lines within the tolerance and saves one line.

Result of deleting self-overlapping lines shows as follows:

This operation is used to make polylines flat and even, so as to improve machining efficiency.

To smooth polylines, do the following:

Select the target polylines.
Do one of the following:
- In menu bar, click Object → Shape Pre-process → Smooth Curve.
- In drawing window, right click and select Smooth Curve.

This operation is used to divide self-intersecting polylines and trim extra lines.

To trim self-intersecting polylines, do the following:

Select the target polylines.
Click Object → Shape Pre-process → Trim Intersection. Inter Trim dialog box pops up:
Enter the value of length.

The system automatically trims lines of which the length is within the value and divides a polyline into several objects.

Result of trimming self-intersecting polylines shows as follows:

This operation is used to turn text into polylines, so as to edit part of the text.

To turn text into polylines, do the following:

Select the target text.
Do one of the following:
- In menu bar, click Object → Shape Pre-process → Text to Polylines.
- In drawing window, right click an select Text to Polylines.

This operation is used to turn closed polylines shaped like circles into circles.

To turn polylines into circles, do the following:

Select the target polylines.
To open Polyline to Circle dialog box, do one of the following:
- In menu bar, click Object → Shape Pre-process → Polylines to Circle.
- In drawing window, right click and select Polyline to Circle.
Polyline to Circle dialog box pops up:
According to the schematic diagram, enter values of Tolerance and Relative Error.

After successfully turning polylines into circles, the following dialog box pops up:

Result of turning polylines into circles shows as follows:
