The diagonal (BD) of the rectangle forms its hypotenuse. In the given figure, ADB forms a triangle right-angled at A. If we know the length and width of a rectangle, we can use Pythagorean Theorem to find the length of its diagonal. The diagonals of a rectangle are the same in length. In the given figure, the two diagonals of the rectangle are AC and BD. The line segments that join the opposite corners of a rectangle are called diagonals. Rectangles are special case of paralleograms. A parallelogram is a quadrilateral whose opposite sides are equal and parallel. Since, a rectangle has parallel sides, we can also call it a right-angled parallelogram.A quadrilateral is a 4-sided closed shape. Since, all the angles of a rectangle are equal, we also call it an equiangular quadrilateral.When a dimension is switched from driven to driving, it changes the geometry if changing a driven dimension to driving causes the sketch to be over-constrained, red indicators appear as usual.This work mode creates an invisible rectangle window, which offers nearest point for selection. When I right click to choose the 'length' option it is greyed out. Construction lines do not change size of a drawing. Driven dimensions reflect the value of the implied dimensions it does not change geometry. I am trying to draw a polygon with very specific dimensions in ArcMap 10.4.You are able to add driven dimensions anywhere a driving dimension can be added.When a dimension added to a sketch over-defines the sketch, the dimension is automatically made 'driven'.Driven dimensions appear light gray and are able to be edited (toggle a driven dimension to driving and then edit, if necessary).Driving dimensions appear black and can be edited.Tap the button to switch to the opposite type of dimension. The button says what type of dimension you have selected. Double tap a dimension to open the Number pad, then tap the Driven/Driving button to switch the dimension type. Driven dimensions are useful for maintaining design intent, such as keeping a clearance or wall thickness above a certain value.Note that you can enter a negative dimension into the dimension box and this will flip the sketch. If you'd like to enter a precise dimension, click on the dimension box, enter the precise dimension, and then click the Enter key. When you drag upward you'll notice that the dimension is created. Then, select the entity to which you want to create a dimension. To start, click on the Dimension icon on the sketch toolbar. You can also use the Show dimensions command in the context menu - the right mouse button - of a sketch, to view existing dimensions. You have the ability to use the Measure tool to measure anything in the graphics area, and some tools allow you to dimension as you sketch. Dimensions are expressed as width by length by height or depth in three. Notice that this second X,Y coordinate established the width (4 units wide) and height (6 units high) of the rectangle and completed the command. For example, a dimension of a rectangular room on a blueprint, 14 11' X 13 10' equates to a room size of 14 feet, 11-inches wide by 13 feet, 10-inches long. Rectangle command offers one option for Dimension, no dialog windows. To complete the rectangle we need to specify the coordinates for the opposite corner to the starting point. You can specify dimensions as driven (reference) or driving. Dimensions in blueprints represent the size of an object in two- or three-dimensional space. This tool can be used to add horizontal, vertical, shortest distance, angular, diametrical, arc length, or radial dimensions to sketch geometry and between sketch geometry and planes. This video will show you how to use the Dimension sketch tool.
