![]() ![]() Carpenter’s RuleĪ carpenter’s rule is also called a folding rule. They are utilized in metalwork, carpentry and construction. In regions where the metric system is prevalent, these instruments are called meter sticks. Yardsticks have metric or imperial measurements. Yardsticks are thin and straight-edged pieces of metal or wood that can measure objects within a yard. This is an advantage because distance markings lie closer to the surface that you are measuring.ĭue to their accuracy, steel rules are a popular choice for technical drawing, geometry and engineering. Since steel is denser than wood, steel rules are thinner than desk rulers. They can be flexible or rigid and have a length ranging from 6 to 12 inches. ![]() Steel rules are flat and have straight edges. Steel RuleĪ steel rule is quite similar to a desk ruler. ![]() They are often about 30 cm in length.ĭesktop rulers are primarily used for drawing and geometry. They have traditionally been made from wood, but nowadays plastic varieties are extremely common. The desk ruler is probably the first thing that comes to mind when you hear the word ‘ruler’. Let’s take a look at the different kinds of rulers and their uses. But, there are many other varieties out there as well. The most commonly used ruler is 12 inches long. These rulers have many uses in printing, carpentry, engineering, geometry and technical drawing. They are also made from a range of materials, which includes plastic, metal and wood. Rulers are also referred to as line gauges. It possesses a straight edge with numbered markings for measuring distances. Understanding Different Ruler Types and Why They Are Useful for YouĪ ruler is a measuring instrument that comes in different materials, shapes and sizes. Flexible Stainless Steel Rulers w/ Cork Backing.Customized Fan Style Multi-Ratio Rulers.Calibrated Certified Rulers Traceable to NIST.Customized Pregnancy Due Date Calculators.Customized Catheter French Scale Rulers.Referring to this implementation should give you an idea of how to go about creating custom ruler types. The appended schema of the HorizontalRuler class is a part of the 'Ruler.cs' file that ships with the Essential Diagram source version. This is done by overriding the .Controls.Diagram control's Diagram.CreateView() method and returning the View subclass that uses your custom rulers. The final step is to instruct the Diagram control instance to use this subclassed View type. This is done by subclassing the .View class used by the Diagram control, overriding the View's CreateHorizontalRuler()/CreateVerticalRuler() methods, and returning instances of your custom ruler types. Once the custom ruler implementation is co mplete, the next step is to instruct your Diagram control instance to use this Ruler type. To customize the diagram rulers, you will have to subclass one of the default ruler classes or the base Ruler type and implement the requisite drawing algorithm from an override of the Ruler.Draw(Graphics) method that is summoned by the View for drawing the ruler. The .View class that implements the diagram control's 'View' component hosts the two rulers and uses them for rendering the ruler gradations while drawing the diagram document. How do I create custom rulers for use in my Diagram?Įssential Diagram uses two classes - .HorizontalRuler and .VerticalRuler - that derive from the base .Ruler class for implementing the standard horizontal and vertical rulers. ![]()
