Printed Wiring Card Reverse Engineering Insertion Mode

Printed Wiring Card Reverse Engineering can not only restore PCB board schematic diagram, layout drawing, gerber file and BOM out from its phsysical sample, but also optimize the printed circuit board layout design for a better performence over its electronics;

Insert mode provides the capability of inserting new points into existing polygons or lines. The 45 degree line clipping is now enforced when selected. Press and hold the shift key while positioning the new point to only clip the line segment to the nearer of the two existing points to 45 degrees.

You can also toggle the 45-degree clipping in the middle of a point insertion by pressing the <Key>. If the shift key is not depressed and the 45 degree line clipping mode is on, both new line segments must be on 45 degree angles – greatly restricting where the new point may be placed. In some cases this can cause confusion as to whether an insertion has been started since the two new lines may be forced to lie parallel on top of the original line until the pointer is moved far from the end points.

Printed wiring card Reverse Engineering can remove objects, change their size or moving them only applies to objects that are visible when the command is executed.

There are several keystrokes and button events referring to an object without identifying its type. Here’s a list of them:

<Btn1> creates (or deletes) an object depending on the current mode.

<Key>BackSpace or <Key>Delete removes the visible object at the cursor location. When more than one object exists at the location, the order of removal is: via, line, text, polygon and element. The drawn layer order also affects the search – whatever is top – most (except elements) is affected before lower items. Basically all this means that what is removed is probably just what you expect. If for some reason it isn’t, undo and try again.

Only one object is removed for each keystroke. If two or more of the same type match, the newest one is removed. Use <Key>s and Shift<Key>s to change the size (width) of lines, arcs, text objects, pins, pads and vias, or to toggle the style of polygons (whether pins and vias automatically have clearances).

<Key>n changes the name of pins, pads, vias, the string of a text object, or the currently displayed label of an element.

<Key>m moves the line, arc, or polygon under the cross hair to the active layer if it wasn’t on that layer already before Printed wiring card Reverse Engineering.

<Key>u (undo) recovers from an unlimited number of operations such as creating, removing, moving, copying, selecting etc. It works like you’d expect even if you’re in the midst of creating something. Shift<Key>r restores the last undone operation provided no other changes have been made since the undo was performed.

<Key>tab changes the board side you are viewing.
