Reverse Engineering Printed Wiring Card
Sometimes it’s useful to fill large areas with solid copper when reverse engineering Printed wiring card. The way to do this is with polygons. Polygons can be created in either the polygon mode or the rectangle mode. In the polygon mode, you’ll have to define each corner of the polygon with a mouse click (Btn1 ) when reverse engineering Printed wiring card. When the last point is clicked exactly on top of the starting point, the polygon is finished. Since this can be hard to do, the Shift-P key will enter the final point for you, closing the polygon. If the 45 degree angle restriction is turned on and you try to close the polygon when it is not possible, you’ll get a warning instead. If you haven’t finished entering a polygon, but want to undo one (or more) of the points that you’ve already defined, use the undo command (U key) before reverse engineering Printed wiring card.
Printed wiring card Reverse Engineering can handle arcs of any angular extent, but when you create an arc with the Arc tool, it will be a quarter circle (this means they always bend a right angle). Arcs are very similar to lines otherwise. They are created on the active layer and have the same thickness that new lines will have. The various clicks for creating lines work pretty much the same way for creating arcs from Printed wiring card Reverse Engineering. In order to make the arc curve in the desired direction, drag the mouse along the tangent line from the starting position towards the end position. If the grid is too coarse, it may not be possible to distinguish whether you’ve moved over then up, or up then over, so if you can’t seem to make the arc go in the direction you want, try pressing the Shift key while drawing the arc from Printed wiring card Reverse Engineering. Decreasing the grid spacing may also help. Alternatively you can draw the wrong arc, then rotate and move it where you want. Like the Line tool, after an arc is drawn a new starting point is established at the end point.
Whenever a starting point is established by either the Line or Arc tools it will be retained if you switch directly between the tools (e.g. F2 key for Lines, F8 key for Arcs if Printed wiring card Reverse Engineering. Arcs can either touch or clear polygons just like lines do. Of course connection searches, undo and all the other features you’d expect work with arcs too.
