3.4 Coordinates and Transformations

This lesson is an overview of the Object Coordinates and Transformation dockers. These dockers aid in the more technical and precise creation and manipulation of objects, giving you greater control over your documents.

3.4 Coordinates and Transformations

Welcome to Getting Started with CorelDRAW. I'm Mary Winkler for tuts+. In this lesson, we'll review the object coordinates and transformation dockers. These dockers aid in the more technical and precise creation and manipulation of objects. In our working document, go to Window, Dockers, Object Coordinates. In this docker, you'll notice options to create and place a variety of objects. Rectangles, circles, polygons, stars, line segments, and curves. This docker allows you to be incredibly precise about the creation and placement of an object. Let's test it out now. Select rectangle and note the options for choosing the rectangle origin point placed within the document on the x and y axis of the page. In the objects dimensions itself, hit create object to make an object. Note that if you remove the object that you just created, newly created ones will appear from it's current position. This can help speed up your object creation process if you want to change where objects are placed or duplicate objects and create new ones from a different starting point. Use the arrows to manipulate the next objects position and dimensions. Or enter numbers in yourself if you have an idea of what values you want for the object. There's also options to manipulate the bounding box itself. Which allows you to scale a single side of an object at a time, versus focusing on each axis. Switch to circles or polygons to get a feel for the creation and placement process as well. I've found that these basic shapes have similar options that once you get a hang of one, you'll understand how to create all of them. Let's check out the line and curve options. Like the other shapes, you can adjust it's dimensions and placement. X and Y1 adjust the lines placement within the page while X and Y2 adjust the line's length and angle. You can also quickly change the line's overall size and angle under object size. Hit Create Object to create new line. The last feature of this docker is the multi-point curve. In order to create a line or curve, you'll need to hit Add Point and enter in your point's coordinates by clicking on X and Y in turn. Then you'll have to add another point and once again enter in that point's coordinates. If you keep clicking add point, each point will appear on the same spot on your page. Create a few points with different coordinates and watch as your multi-line object takes form. Then close the object by hitting Auto Close, Open Curve. The placement and creating of precise objects is rather easy with the object coordinates docker. Let's check out the other docker featured in this lesson, the transformation docker. Head over to Window, Transformations, Position. This will open the transformations docker starting with the position options. Draw a shape with an object tool like a rectangle and test out the placement of the selected object or object copies. Similar to the object coordinates docker, this docker places and manipulates objects. I've entered in arbitrary numbers for the X and Y coordinates. Chosen two copies, and hit apply. With this option, you can move your selected objects or choose where copies of that object will be placed in succession. Next up we have Rotate, which rotates an object or successive copies of said object. Like placement before it, enter an arbitrary degree to test it out. Enter in zero copies to rotate the selected object. Or choose a low number to get a feel for rotating copies of an object. You can also adjust the center of the rotation X and Y coordinates. Third in the list is scale and mirror. This option allows you to re-size an object by a percentage, and mirror it too. Hitting Apply multiple times re- sizes the object by the same percentage again and again. If you add copies, you'll created multiple objects that are successively smaller than the last based on that percentage. You can also mirror objects, as well. This is best shown with an asymmetrical object. I'll draw something quick with the Freehand tool and keep my scale at 100%. Toggle Horizontal Mirror on and Vertical Mirror off and a mirrored copy of the shape is created once I hit apply. Next up is size. Instead of re-sizing based on a percentage, size re-size is according to the dimensions you specify. It's a fairly straightforward setting and I encourage you to spend more time with it if you want. But we're gonna move on to the final options in the transformation docker. Skew is an option that slants a selected object horizontally, vertically or both. Entering an arbitrary number for the degree in either X or Y and hit apply. Like size, skew is fairly straightforward in it's functions. You can create skewed copies of your object or skew the object itself. Whatever you do, know that you've gotten through the transformation docker and have a better handle on creating and manipulating objects in a precise and calculated manner. Thank you so much for watching this lesson on the Object Coordinates and Transformation Dockers. In our next lesson, we'll go over the text docker and all it has to offer.
