Haochen CAD tutorial GPS line number naming rules for overhead lines
When using Haochen CAD overhead lines to optimize the design of software design lines, we often need to apply GPS data. GPS data not only has the coordinates of the measuring points (X, Y, Z axis coordinates), but also requires a little number of naming rules, such as straight rods, corner bars, houses and other types of point names. Let's take a look at how to name the GPS points after importing the measured GPS data into the Haochen CAD overhead line optimization design 2011.
1, the naming rules of the name
The named length of the corner must be less than 5 lengths, and the name of the straight pile and other broken step points must be greater than or equal to 5 lengths, such as the named position of the broken step point j1—101, j1—102gl, j1-1031, and the straight pile is j1 -z1 (lowercase), where j1 is the corner name can be arbitrarily replaced with other corner names, such as j2, j3... Straight piles must be named with the letter z.
2, the naming rules of the house
At the end of the point name, the letter f (lowercase) is added. The first corner of the house ends with f1, the second corner points with f2, and the third ends with f3. There are two ways to draw a house: one is the two-point method, the other is the common method, and the other is the three-point method. The 2-point method is to add the width of the house after the first corner of the room. For example, j1-101f18 and j1-101f2 represent an 8m wide house, and j1-102f112 and j1-102f2 represent a 12m wide house. The 3 point room is to add f1, f2, and f3 respectively after the corner of the corner. For example, j1-103f1, j1-103f2, and j1-103f3 represent a 3 point room (see Figure 1).

3. The naming method of spanning
Add the letter v (lowercase) at the end of the name, and then add the voltage level code after the v to the height of the span. For example, j1-104, j1-104v388 represents a 380v span of 8m in height. Where j1-104 is the direction of the span, j1-104v388 is the cross-section point, 38 is the voltage level code, and 8 is the height (Figure 2).

Among them, the voltage level and the voltage code have their own corresponding relationship (Figure 3)
