2. MODELING

CHAPTER 2 "MODELLING" 113 6.2.1 Metal frames Select the "Geometry" based on the drawing and the x and z iterations. The structural elements that will take part in the construction must have the corresponding checkbox. For each structural element, select the corresponding cross-section. Click on the default cross- section and in the dialog box select your own cross-section. OBSERVATION: Whenever you modify a default cross-section, in the dialog box specify the layer to which it will belong. It is important to have the correct correspondence of the elements in the layers so that you can take advantage of the program commands that act globally (for each layer) and save a lot of time. In order to calculate the number of pegs, enter in cm: "Offset": the distance of the first peg from the headstock, "Max distance": the maximum distance between the pegs and select "Calculate". The program automatically calculates the number of stripes per stripe. Alternatively, enter the two numbers (left and right) directly. Calculate the number of μηκίδων (see previous) and uncheck the checkboxes of μηκίδων in the directions that do not exist. It is possible to install thimbles of different cross-sections per direction. Just select the default cross-section and in the dialogue box set the new one.
