ACD/ChemSketch Tutorial 78 Creating Graphical Objects 9.2.1 Drawing a Curve This section describes how to draw a curve: 1. Switch to the Draw mode by clicking on the General toolbar. 2. Form the File menu, choose New to start a new document. 3. On the Drawing toolbar, click Polyline 5. Release the mouse button. 6. Move the mouse up to draw the first segment of the curve. 7. Drag horizontally to the right to stretch the control lines. By changing the length of the control lines you can modify the curve segment. 8. Release the mouse button. 9. Move the mouse down to draw the next segment. . 4. Drag horizontally to the right from the starting point of the curve to stretch the control line. horizontally horizontally 10.Repeat the above steps to draw the next two segments. 11.Right-click to finish drawing the curve. Tip When drawing with the Polyline tool, it is helpful to remember that a “click” will create an endpoint, a cusp, or a sharp angle, and a “drag” will create a curve: ACD/ChemSketch Tutorial 79 Creating Graphical Objects 9.2.2 Modifying a Curve The first time you draw with the Polyline tool you might have some trouble getting the curve to turn out the way you want. For example, the first attempt might produce something like this: 1. If the curve is not already selected, click Select/Move/Resize 2. On the Editing toolbar, click Edit Nodes can be modified: and then click the curve. . This will show all the nodes of the polyline that 3. Click the third node, and you will see the node selected and the control lines appear: 4. Drag the control lines, then select and modify the other nodes until the curve looks as you like. Tip When using the Edit Nodes tool, you can manipulate nodes using the buttons on the Node toolbar that appears. For example, you can select several nodes by clicking on them when holding down SHIFT, and then align them by choosing the corresponding button on the toolbar. 9.2.3 Drawing the X and Y axes To accomplish drawing of a reaction diagram, the axes are required. Make sure that the Line and Arrow tools are active. , choose the one-way arrow . 1. From the Tools menu, choose Arrow Style Panel. On the Arrow panel that appears, from the Arrow Type drop-down list 2. From the Options menu, choose Snap on Grid and/or Show Grid to make your drawing easier. 3. Click at the origin of coordinates and drag the mouse up vertically to draw the Y-axis. ACD/ChemSketch Tutorial 80 Creating Graphical Objects 4. Click at the origin of coordinates and drag the mouse horizontally to the right to draw the Xaxis. 5. Add inscriptions Energy and Reaction Coordinate using the Text tools. and Rotate 90° Here’s a challenge. Use the Text tool to print a word in the workspace. Select it and change its font size to, say, 36 points, and its color to yellow. Now use the Polyline tool to write the word over top. (Hint: “write” the word as tool liberally.) best as you can and then use the Edit Nodes C hemistry 6. On the General toolbar, click New Page . 9.3 Drawing Different Kinds of Orbitals This section is based on the movie orbital.exe which can be downloaded from our Web site or found in the Movies folder. 9.3.1 Drawing a p-orbital We are going to draw the following orbital: Make sure you are in the Draw mode and, on the Drawing toolbar, click Polygon . 1. Drag horizontally to the right from the starting point of the orbital to stretch the control line. ACD/ChemSketch Tutorial 81 Creating Graphical Objects 2. Release the mouse button. 3. Move the mouse down to draw the body of the orbital. 4. Click to fix the orbital. Note If the shape of the curve is not what you want, use the Edit Nodes tool. 5. Right-click twice to finish drawing the orbital and to quickly switch to the Select/Move/Resize tool. Point to the selected orbital; and drag it down holding down CTRL to make a copy of the drawn orbital. 6. On the Editing toolbar, click Flip Top to Bottom Align the segments by moving them. to flip the lower segment of the orbital. Tip To align the elements more precisely, make sure that the Snap on Grid is not selected on the Options menu. 7. Click the gray color on the Color Palette to change the fill color of the orbital segment. Tip To quickly center the orbital segments, select them and click Center Horizontally . . Now you 8. Select both segments of the orbital and, on the Editing toolbar, click Group can manipulate the segments as a single object, e.g., rotate using the Select/Move/Rotate tool. 9.3.2 Drawing a d-orbital In this section, we will d...
