The first step is to draw a base element, an AND gate block. This drawing will serve later as a collection of available symbols and you should not only draw the symbols but fully detail them as well. In addition you should probably activate Display grid and Guides when moving as well as Snap to grid (see Positioning objects with snap functions). These values are all random values and you would normally substitute values that suit your own needs.įor the drawing we used a measurement unit of millimeters, a grid spacing of 5 mm, and a grid subdivision of 4 points. The connections to the symbols should have a length and separation of at least 5 mm. So that the edges of the building block symbols do not coincide with the wiring, they should be 8 mm wide and 8 mm high. Logic Symbol library Working with the Position and Size dialog The logic symbols shown below form the building block library for our scale drawing. The exact meaning of the individual symbols is not described here as we are only interested in the drawing techniques used to produce the diagram. The example used for this chapter is a drawing of a Logic Circuit Diagram. 4.8.2 Transform a curve into a polygon or a polylineĭraw is not a CAD (computer-aided design) program but a graphics program with which you can produce drawings to a scale.4.8.1 Transform a polygon or a polyline into a curve.4.8 Transform complete curves, polylines and polygons.4.7.2 Transform a Bézier curve into a straight segment.4.7.1 Transform a straight segment into a Bézier curve.4.7 Transformation between straight line and Bézier curve.4.4 Drawing a succession of Bézier curves.3.1 Configuring text elements with styles.1.4 Drawing a logic circuit diagram using the Gallery.1.3 Copying individual pictures to the Gallery.1.1 Working with the Position and Size dialog.
