Lesson 3. Drawing a sin or zigzag in AutoCAD
Continuing with the lesson the previous day, today we begin acquainted with the arc command, long curvy lines to draw a sinusoidal or zig zag shape.(Note: under each post can file for you to download and practice).
1. The first, command of arc be part of a circle with a radius of a given, we type A (Arc) with the aim of drawing successive curves create beautiful sinusoida.
With 7 points given, now we giờ ta đi drawing consecutive curves to create a sinusoidal, you are ready.
Typing A/Enter, select the first point, select the second point and select the third point, here we draw arc base on 3 point given .
Doing the same with points 3, 4, 5, we are arcs.
Point 5, 6, 7 nexting.
This is irregular the sinusoidal due to different radius.
Continuing with drawing arcs symmetrical.
Typing A/Enter. Selecting the first point, next typing 500 Tab 45/Enter.
Continuing with next point (500; –45º).
We will be shown below.
Next, you create multiple contiguous, how to create beautiful the sinusoidal as image below.
