CHAPTER 11 'FORMWORK' 41 δ. Angle degrees : Calculate and plot the size of an angle in degrees. The indicated dimension is in the form of an arc between the sides of the indicated angle. Mode of Use : 1. You activate the command "DIMENSIONS>> Angle Fates". 2. Select with the mouse the position where the dimension will be drawn. The program will draw an arc with a radius defined by the point you indicate and the vertex of the corner. 3. You select the two half-lines (sides of the corner) that you want to dimension. The program will dimension the angle defined between the first and second semi-line in the order defined. Positive angle direction is counterclockwise. If the option is activated in the "Parameters - Dimensions", then before entering the dimension of the angle you will be asked to confirm it in a dialog box that opens. ε. Arc: Length: The length of the arc is calculated and displayed. The dimension line is an arc concentric with the drawn one at the position indicated with the mouse. Radius: Enter the length of the radius of the circle of which the drawn arc is a part. Draw the radius from the center of the arc to a point in the direction indicated with the mouse. I= : Similar to Length option. Here the calculated dimension is entered in form l=a, where a is the length of the arc, and an arrow is drawn indicating the arc being dimensioned. R=: Similar to the previous option except that the length of the radius is indicated here. How to use : 1. Activate the command "DIMENSIONS>> Arc dimensions" (Length, Radius, l or r). 2. Use the mouse to point to a point on the screen where the dimension will be drawn. This can be inside or outside the arc. 3. You select the arc you want to dimension and immediately the dialog box for confirming the dimension opens, if the corresponding option in the dimension parameters is enabled. Pressing the button displays the calculated dimension. f. Circle - Horizontal/Vertical/Night: The dimension you enter refers to the diameter of the circle you indicate and is drawn parallel to the horizontal or vertical axis or in a random position respectively, at the point you select with the mouse. Circumference l = : Write the length of the circumference of the circle in the form l=a, and draw an arrow indicating the circle dimensioned. Radius r : Similar to the previous option except that the radius of the circle is indicated here.
