Automatic Chaining of New Contours to Existing Ones

Description

When creating a new contour, this will optionally be chained to existing contours in the drawing. This options is controlled by a new Drafting default keyword AUTO_CHAIN with values "Yes" or "No" (system default).

The system will compare the start and ending points of a new contour with the ones of existing contours structurally belonging to the same component as the created one. If any of them coincides with the start/ending points of the new contour it will be chained to the new contour. Note that at most two contours can be chained to the new geometry, one in the beginning and one in the end.

The criterion for an existing contour to be chained to the created one is thus:

• AUTO_CHAIN is set to "Yes"

• The existing contour belongs to the same component as the created one

• The existing contour is not closed

• The start or ending points of the existing contour coincides (zero tolerance) with the start/ending points of the created contour

The Automatic Chain concept is implemented in the following functions:

• Insert/Polyline

• Insert/Staircase

Benefits

This will improve productivity. Instead of invoking the Modify/Chain function as post-action, the chaining is performed automatically as new contours are created.
