![]() The blue-print process was characterized by light. Invented in the 19th century, the process allowed rapid and accurate reproduction of documents used in construction and industry. Or, apply the law of cosines immediately. Or, use the triangle thats already there, having 2 angles equal to (180-22.5)/2 degrees, and apply the law of sines. By using the Reference Circle you can define at what elevation the second floor should be. A blueprint is a reproduction of a technical drawing, documenting an architecture or an engineering design, using a contact print process on light-sensitive sheets. Bisect the angle to get 2 right triangles with known hypotenuse and angles, then use sin to get the sides opposite the 22.5/2 degree angles. If your lower floor has varying wall heights then when you assemble your floors the lowest point of your second floor will be at the elevation of the tallest wall on the first floor. Computer functions are indicted by a hexagon and programmable logic controller (PLC) functions are shown as a triangle inside a square. Shared control/display elements are circles surrounded by a square. ![]() Basically this means there are different methods of showing the same part. The Reference Circle will also affect the elevation of your assembled floors. Discrete instruments are indicated by circular elements. Projections are different ways of representing parts on a blueprint. All three corners must lie on the larger circles, and two edges must be tangents to the smaller one. In blueprints, it is a small circle with a 'T' inside of it. 2.5.13 Let (triangle,ABC ) be a right triangle. Show that the circumscribed and inscribed circles of (triangle,ABC ) have the same center. Use a ruler and a protractor to measure the sides (a, b, c) and the angles (A, B, C) of the triangle. Then draw a larger circle with radius 625 625 around that same center. 2.1.10 Draw a circle with a radius of 2 inches and inscribe a triangle inside the circle. The Reference Circle has a special property that the others do not. Here is how you could construct this situation: You could start by drawing the circle, with radius 350 2 175 350 2 175 around any point. If 'Drawing A' uses a Triangle Reference Point and 'Drawing B' uses the Square Reference Point and you perform one of the above mentioned functions then the reference points will have no effect. Any of these can be used but you must use the same type on each drawing you want to overlay, merge, or assemble. The four Reference Point types are Reference Circle, Reference Triangle, Reference X, and Reference Square. They can also be used as a means for assuring an exact placement when you merge two drawings together. Reference Points can be used to align drawings when you Overlay them or Assemble them for 3D. Understanding how these work can make your life much easier. 3) circle with two lines through it like lollipop with GFCI next to it. ![]() 2) circle with two lines through it like lollipop. 1) circle with a line through it like lollipop. SoftPlan has 4 different Reference Points available. Match the common electrical blueprint symbols to the proper description. ![]()
