Using a Scale Ruler;
Using a Scale Ruler; What is Scale and why do we use it. Designers and Architects use ‘scale’ so they can draw on paper a small replica of the real space, building or layout as it will be when built, but in miniature, so that everything is in proportion and you can carry the drawings around and work on them. There are different scales you can use giving you larger scale drawings or small scale. An example of this is if you look at the Deeds of your house you should find a ‘site location plan to scale’ at possibly 1:500. It just shows the outline of your property in relation to other buildings and roads etc It does not show detail of the building but … will show out-houses or drive ways. It also has a red line around your boundary which confirms the land your property will occupy and forms part of your contract on purchase. Architects will often use a scale of 1:100 to draw up an outline of a new building and it will show details of how the property is divided up into rooms, stairs entrances and different floor levels. Using the scale of 1:50 you can put a lot more detail in, showing basic furniture layouts within the rooms and identifying bathrooms and kitchens with fitted units shown and changes of ceiling height, floor levels and is often used for planning applications with a site plan or a plan at 1:100 depending on the type of application and the details required. -

Handout 1.Tools
HANDOUT 1.TOOLS: A tool is an object made to help the man constructing, repairing, or modifying other objects. E.g.: Wrench Drill Hammer Screwdriver L We can classify them in tools and power tools, power tools are those that have a motor (e.g.: a drill) All the different tools have different uses, we have to use them properly for the use they have been designed. 1. Draw a tool you know, find the name and the use of it in English and Catalan and write it under your drawing. Use the dictionary and the help of your classmates and the teacher. English Catalan Name: Nom: Operation: Acció: 2.
