You may want to include graphical elements or text in your schematic design. PADS Maker Schematic allows you to add boxes, circles, lines, arcs, and text to a schematic.
Introduction to Graphical Objects
The procedure is similar for adding all graphical objects to a schematic:
- Go to the Add menu and select Arc, Box, Circle, or Line/Polyline. The Line/Polyline option allows you to not only create singular lines, but also to create complex objects such as polygons.
- Click-and-drag on the schematic where you want the object to be placed.
- For Arcs: Press left mouse button and drag while holding down space bar to set the arc. Another option is to press left mouse button, and while dragging also depress right mouse button at the same time. After placing the initial line, press Space or right-click to define arc depth. Release the left mouse button to finalize the arc.
After placing an object, you can define Color, Line Style, Line Width, and Fill Type in the Properties window.
Notice that next to each Graphical Object is a letter identifying its short-cut. For example, to create an arc, you can either choose Arc from the drop-down menu, or you can type Shift+A.
1. After choosing the Add>Circle, click and drag where you want your circle to be. Notice the cursor for the Circle object circled in red below.
2. Now left-click on the mouse, and drag your circle to its desired size. Notice the grab bars connected to the four sides of your Circle. You can use these to resize your object.
The procedure for creating Arcs and Polygons (using Line/Polyline) is a bit different.
- To create an Arc, go to Add menu in your toolbar and select Arc. Then you will see the Arc cursor as shown below.
2. Left-click and drag the Arc line until you achieve the desired length of your Arc.
3. To establish Arc depth, you have one of two options. You can hold the Space bar, and then drag your Arc line left or right while continuously holding down the left-click mouse button until you establish your desired depth.
4. Once you have your desired depth defined, release the left-click mouse button to finalize your Arc. Alternatively, after establishing the length of your Arc line, you can press and hold the right-click mouse button once, and then while holding down the left-click mouse button, drag your mouse left or right until you reach the desired depth.
5. Again, once your desired Arc is defined, releasing the left-click mouse button will finalize your Arc.
Notice that once your Arc is finalized, you will have three grab bars from which to choose if you want to manipulate your image further. Hovering over one of the grab bars will reveal red X's over all three grab bars indicating alternate points of manipulation.
To create a Polygon, you must select Line/Polyline from the Add option in your toolbar. The Line/Polyline option will allow you to create simple lines or to create polygons by creating and connecting various lines.
- To create a triangle, select Line/Polyline to reveal the line cursor.
- Now left-click and drag that cursor to the desired length of one side of my triangle.
- To complete the line, release the left-click mouse button.
Add line two.
And line 3.
With Polygons, you have properties that you can change in addition to those mentioned below. See Polygon Properties.
- To add text to a schematic, click Add > Text.
- Click on the location where you would like to add the text, and fill in the blank field at the prompt.
3. Next click on where you want your text box to appear. It will be small at first, but you can scale it by right-clicking on the text box and selecting Scale. However, if you want to keep the text small, you can simply forward scroll on your mouse to zoom in. See Manipulate Text for more details.
4. Now double click on your left mouse button to change the text.
Adjusting Graphical Properties
To determine the outline and fill color, select the desired color from the drop-down box next to Color under Properties.
You may select Line Style and choose from the drop-down list whether you want a Solid, Dot, Dash, or some other outline style.
Line Width can similarly be changed via the drop-down box.
And finally, you can choose your Fill Style. In this case, I will choose Solid.
You can change the text under Properties and Text. Simply click in the space next to Text and enter what you want. Once done, hit return to see the change.
You can also change the text's Color, Font, and Size as you can for the Graphical Objects.
To change Polygon properties, first click in the middle of your Polygon to select it. Be careful not to just select one line if you want the entire object changed. As with the other objects, you can also change the Polygon's Color, Line Style, and Line Width. However, now you have the added option of adding Arrows to the Starting Cap and Ending Cap of any or all sides of your Polygon.
- After selecting your entire Polygon, click on the side you want to add an arrow to.
- Next add an arrow type at your Starting and/or Ending Cap(s).
3. You can add additional arrows to the Ending and/or Starting Cap(s) of each one of your lines by selecting those lines individually rather than selecting the entire polyon before adding the arrow property.
For options on manipulating any of your objects, you can hover over one of them and right-click. This will reveal a variety of options for changing your object. The following can be used for any Graphical Object, but I will use the Arc object as an example.
The following demonstrates the effect of selecting Rotate on the Arc object.
The following demonstrates the effect of selecting Flip on the Arc object.
The following demonstrates the effect of selecting Mirror on the Arc object.
If you select Scale, you will be given a pop-up allowing you to enter a Scale factor. The Scale factor determines how much the object is to be made larger or smaller. For example, if you enter "2", then your object will be doubled in size. However, if you enter "0.5", your object will be halved in size.
Rotate About and Move Point of Origin
Additionally, you can manipulate any object by rotating it about its point of origin. This point of origin can also be moved so that the object can be rotated about a different point.
- To move the origin point, hover over the circle that indicates the point at which you will drag and rotate your object.
2. To rotate, hover over and left-click the end-point circle and drag it to the desired location as shown below.
3. To move the origin of rotation, first hover over the endpoint circle to reveal the origin of rotation. The origin of rotation will be the circle with the cross-hairs.
4. Next, hover over the origin of rotation. This will reveal a hand icon which will allow you to drag the origin of rotation. Left-click and drag the origin of rotation wherever you want it.
5. To rotate the object, left-click and drag the top circle as shown below.
6. The origin of rotation can be placed anywhere, whether on the actual object or not.
You can move any Graphical Object to another part of the schematic by clicking on it and moving its dashed box.
The rules for finding the origin of rotation and rotating the Text object are the same as it is for Graphical Objects. With Text objects, however, you have the added ability to change the Rotation and Origin under the Properties table.
To enlarge your text, you can scale it by right-clicking on the text box and selecting Scale.
Or to keep your text small, as you are much more likely to want to do, but still have the text more visible to you, simply scroll forward on your mouse scroll button.
